text: The ability of primordial gas to cool in proto-galactic haloes exposed to
Lyman-Werner (LW) radiation is critically dependent on the self-shielding of H_2.
We perform radiative transfer calculations of LW line photons, post-processing
outputs from three-dimensional adaptive mesh refinement (AMR) simulations of haloes
with T_vir > 10^4 K at redshifts around z=10. We calculate the optically thick
photodissociation rate numerically, including the effects of density, temperature,
and velocity gradients in the gas, as well as line overlap and shielding of H_2
by HI, over a large number of sight-lines. In low-density regions (n<10^4 cm^-3)
the dissociation rates exceed those obtained using most previous approximations
by more than an order of magnitude; the correction is smaller at higher densities.
We trace the origin of the deviations primarily to inaccuracies of (i) the most
common fitting formula (Draine & Bertoldi 1996) for the suppression of the dissociation
rate and (ii) estimates for the effective shielding column density from local
properties of the gas. The combined effects of gas temperature and velocity gradients
are comparatively less important, typically altering the spherically averaged
rate only by a factor of less than two. We present a simple modification to the
DB96 fitting formula for the optically thick rate which improves agreement with
our numerical results to within approx. 15 per cent, and can be adopted in future
simulations. We find that estimates for the effective shielding column can be
improved by using the local Sobolev length. Our correction to the H_2 self-shielding
reduces the critical LW flux to suppress H_2-cooling in T_vir>10^4 K haloes by
an order of magnitude; this increases the number of such haloes in which supermassive
(approx. M=10^5 M_sun) black holes may have formed.

text: At optical frequencies the radiation produced by a source, such as a laser,
a black body or a single-photon emitter, is frequently characterized by analysing
the temporal correlations of emitted photons using single-photon counters. At
microwave frequencies, however, there are no efficient single-photon counters
yet. Instead, well-developed linear amplifiers allow for efficient measurement
of the amplitude of an electromagnetic field. Here, we demonstrate first- and
second-order correlation function measurements of a pulsed microwave-frequency
single-photon source integrated on the same chip with a 50/50 beam splitter followed
by linear amplifiers and quadrature amplitude detectors. We clearly observe single-photon
coherence in first-order and photon antibunching in second-order correlation function
measurements of the propagating fields.

text: Superconducting circuits have been successfully established as systems to
prepare and investigate microwave light fields at the quantum level. In contrast
to optical experiments where light is detected using photon counters, microwaves
are usually measured with well developed linear amplifiers. This makes measurements
of correlation functions - one of the important tools in optics - harder to achieve
because they traditionally rely on photon counters and beam splitters. Here, we
demonstrate a system where we can prepare on demand single microwave photons in
a cavity and detect them at the two outputs of the cavity using linear amplifiers.
Together with efficient data processing, this allows us to measure different observables
of the cavity photons, including the first-order correlation function. Using these
techniques we demonstrate cooling of a thermal background field in the cavity.

text: A wide range of experiments studying microwave photons localized in superconducting
cavities have made important contributions to our understanding of the quantum
properties of radiation. Propagating microwave photons, however, have so far been
studied much less intensely. Here we present measurements in which we reconstruct
the quantum state of itinerant single photon Fock states and their superposition
with the vacuum by analyzing moments of the measured amplitude distribution up
to fourth order. Using linear amplifiers and quadrature amplitude detectors, we
have developed efficient methods to separate the detected single photon signal
from the noise added by the amplifier. From our measurement data we have also
reconstructed the corresponding Wigner function.

text: Creating a train of single photons and monitoring its propagation and interaction
is challenging in most physical systems, as photons generally interact very weakly
with other systems. However, when confining microwave frequency photons in a transmission
line resonator, effective photon-photon interactions can be mediated by qubits
embedded in the resonator. Here, we observe the phenomenon of photon blockade
through second-order correlation function measurements. The experiments clearly
demonstrate antibunching in a continuously pumped source of single microwave photons
measured by using microwave beam splitters, linear amplifiers, and quadrature
amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering
in Mollow-triplet-like spectra.

text: Continuous variable entanglement between two modes of a radiation field is
usually studied at optical frequencies. Here we demonstrate experiments that show
the entanglement between microwave photons of different energy in a broadband
squeezed beam. We use a Josephson parametric amplifier to generate the two-mode
correlated state and detect all four quadrature components simultaneously in a
two-channel heterodyne setup using amplitude detectors. Analyzing two-dimensional
phase space histograms for all possible pairs of quadratures allows us to determine
the full covariance matrix, which is in good agreement with the one expected for
a two-mode squeezed state.

text: Microwave cavities with high quality factors enable coherent coupling of distant
quantum systems. Virtual photons lead to a transverse interaction between qubits
when they are nonresonant with the cavity but resonant with each other. We experimentally
investigate the inverse scaling of the interqubit coupling with the detuning from
a cavity mode and its proportionality to the qubit-cavity interaction strength.
We demonstrate that the enhanced coupling at higher frequencies is mediated by
multiple higher-harmonic cavity modes. Moreover, we observe dark states of the
coupled qubit-qubit system and analyze their relation to the symmetry of the applied
driving field at different frequencies.

text: We report the first concurrent determination of conductance (G) and thermopower
(S) of single-molecule junctions via direct measurement of electrical and thermoelectric
currents using a scanning tunneling microscope-based break-junction technique.
We explore several amine-Au and pyridine-Au linked molecules that are predicted
to conduct through either the highest occupied molecular orbital (HOMO) or the
lowest unoccupied molecular orbital (LUMO), respectively. We find that the Seebeck
coefficient is negative for pyridine-Au linked LUMO-conducting junctions and positive
for amine-Au linked HOMO-conducting junctions. Within the accessible temperature
gradients (<30 K), we do not observe a strong dependence of the junction Seebeck
coefficient on temperature. From histograms of thousands of junctions, we use
the most probable Seebeck coefficient to determine a power factor, GS2, for each
junction studied, and find that GS2 increases with G. Finally, we find that conductance
and Seebeck coefficient values are in good quantitative agreement with our self-energy
corrected density functional theory calculations.

text: We measure electronic conductance through single conjugated molecules bonded
to Au metal electrodes with direct Au–C covalent bonds using the scanning tunneling
microscope based break-junction technique. We start with molecules terminated
with trimethyltin end groups that cleave off in situ, resulting in formation of
a direct covalent σ bond between the carbon backbone and the gold metal electrodes.
The molecular carbon backbone used in this study consist of a conjugated π system
that has one terminal methylene group on each end, which bonds to the electrodes,
achieving large electronic coupling of the electrodes to the π system. The junctions
formed with the prototypical example of 1,4-dimethylenebenzene show a conductance
approaching one conductance quantum (G0 = 2e2/h). Junctions formed with methylene-terminated
oligophenyls with two to four phenyl units show a 100-fold increase in conductance
compared with junctions formed with amine-linked oligophenyls. The conduction
mechanism for these longer oligophenyls is tunneling, as they exhibit an exponential
dependence of conductance on oligomer length. In addition, density functional
theory based calculations for the Au–xylylene–Au junction show near-resonant transmission,
with a crossover to tunneling for the longer oligomers.

text: We investigate the binding and energy level alignment of 2,3,5,6-tetramethyl-1,4-benzenediamine
(TMBDA) on Au(111) through a combination of helium atom scattering (HAS), X-ray
photoemission (XPS), and scanning tunneling microscopy (STM). We show that TMBDA
binds to step edges and to flat Au (111) terraces in a nearly flat-lying configuration.
Through combination of HAS and STM data, we determine that the molecules are bound
on step edges with an adsorption energy of about 1.2 eV, which is about 0.2 eV
stronger than the adsorption energy we measure on flat surface. Preferential bonding
to the under-coordinated Au atoms on step edges suggests that the molecules bind
to Au through the nitrogen lone pair. Finally, STM measurements on TMBDA in these
two different adsorption configurations show that the highest-occupied molecular
orbital is deeper relative to Fermi for the more strongly bound molecules on step
edges, confirming that the nitrogen bonds through charge donation to the Au.

text: Understanding the electrical properties of semiconducting quantum dot devices
have been limited due to the variability of their size/composition and the chemistry
of ligand/electrode binding. Furthermore, to probe their electrical conduction
properties and its dependence on ligand/electrode binding, measurements must be
carried out at the single dot/cluster level. Herein we report scanning tunneling
microscope based break junction measurements of cobalt chalcogenide clusters with
Te, Se and S to probe the conductance properties. Our measured conductance trends
show that the Co–Te based clusters have the highest conductance while the Co-S
clusters the lowest. These trends are in very good agreement with cyclic voltammetry
measurements of the first oxidation potentials and with density functional theory
calculations of their HOMO–LUMO gaps.

text: The conductance of individual 1,4-benzenediamine (BDA)–Au molecular junctions
is measured in different solvent environments using a scanning tunneling microscope
based point-contact technique. Solvents are found to increase the conductance
of these molecular junctions by as much as 50%. Using first principles calculations,
we explain this increase by showing that a shift in the Au contact work function
is induced by solvents binding to undercoordinated Au sites around the junction.
Increasing the Au contact work function reduces the separation between the Au
Fermi energy and the highest occupied molecular orbital of BDA in the junction,
increasing the measured conductance. We demonstrate that the solvent-induced shift
in conductance depends on the affinity of the solvent to Au binding sites and
also on the induced dipole (relative to BDA) upon adsorption. Via this mechanism,
molecular junction level alignment and transport properties can be statistically
altered by solvent molecule binding to the contact surface.

text: Controlling electron transport through a single-molecule device is key to
the realization of nanoscale electronic components. A design requirement for single
molecule electrical devices is that the molecule must be both structurally and
electrically connected to the metallic electrodes. Typically, the mechanical and
electrical contacts are achieved by the same chemical moiety. In this study, we
demonstrate that the structural role may be played by one group (for example,
a sulfide) while the electrical role may be played by another (a conjugated chain
of C═C π-bonds). We can specify the electrical conductance through the molecule
by modulating to which particular site on the oligoene chain the electrode binds.
The result is a device that functions as a potentiometer at the single-molecule
level.

text: We simultaneously measure conductance and force across nanoscale junctions.
A new, two-dimensional histogram technique is introduced to statistically extract
bond rupture forces from a large data set of individual junction elongation traces.
For the case of Au point contacts, we find a rupture force of 1.4 ± 0.2 nN, which
is in good agreement with previous measurements. We then study systematic trends
for single gold metal−molecule−metal junctions for a series of molecules terminated
with amine and pyridine linkers. For all molecules studied, single molecule junctions
rupture at the Au−N bond. Selective binding of the linker group allows us to correlate
the N−Au bond-rupture force to the molecular backbone. We find that the rupture
force ranges from 0.8 nN for 4,4′ bipyridine to 0.5 nN in 1,4 diaminobenzene.
These experimental results are in excellent quantitative agreement with density
functional theory based adiabatic molecular junction elongation and rupture calculations.

text: Understanding electron transport across π−π-stacked systems will help to answer
fundamental questions about biochemical redox processes and benefit the design
of new materials and molecular devices. Herein we employed the STM break-junction
technique to measure the single-molecule conductance of multiple π−π-stacked aromatic
rings. We studied electron transport through up to four stacked benzene rings
held together in an eclipsed fashion via a paracyclophane scaffold. We found that
the strained hydrocarbons studied herein couple directly to gold electrodes during
the measurements; hence, we did not require any heteroatom binding groups as electrical
contacts. Density functional theory-based calculations suggest that the gold atoms
of the electrodes bind to two neighboring carbon atoms of the outermost cyclophane
benzene rings in η2 fashion. Our measurements show an exponential decay of the
conductance with an increasing number of stacked benzene rings, indicating a nonresonant
tunneling mechanism. Furthermore, STM tip−substrate displacement data provide
additional evidence that the electrodes bind to the outermost benzene rings of
the π−π-stacked molecular wires.

text: Charge transport across metal–molecule interfaces has an important role in
organic electronics1. Typically, chemical link groups such as thiols2 or amines3
are used to bind organic molecules to metal electrodes in single-molecule circuits,
with these groups controlling both the physical structure and the electronic coupling
at the interface. Direct metal–carbon coupling has been shown through C60, benzene
and π-stacked benzene4,5,6,7, but ideally the carbon backbone of the molecule
should be covalently bonded to the electrode without intervening link groups.
Here, we demonstrate a method to create junctions with such contacts. Trimethyl
tin (SnMe3)-terminated polymethylene chains are used to form single-molecule junctions
with a break-junction technique2,3. Gold atoms at the electrode displace the SnMe3
linkers, leading to the formation of direct Au–C bonded single-molecule junctions
with a conductance that is ∼100 times larger than analogous alkanes with most
other terminations. The conductance of these Au–C bonded alkanes decreases exponentially
with molecular length, with a decay constant of 0.97 per methylene, consistent
with a non-resonant transport mechanism. Control experiments and ab initio calculations
show that high conductances are achieved because a covalent Au–C sigma (σ) bond
is formed. This offers a new method for making reproducible and highly conducting
metal–organic contacts.

text: Many membrane channels and receptors exhibit adaptive, or desensitized, response
to a strong sustained input stimulus, often supported by protein activity-dependent
inactivation. Adaptive response is thought to be related to various cellular functions
such as homeostasis and enlargement of dynamic range by background compensation.
Here we study the quantitative relation between adaptive response and background
compensation within a modeling framework. We show that any particular type of
adaptive response is neither sufficient nor necessary for adaptive enlargement
of dynamic range. In particular a precise adaptive response, where system activity
is maintained at a constant level at steady state, does not ensure a large dynamic
range neither in input signal nor in system output. A general mechanism for input
dynamic range enlargement can come about from the activity-dependent modulation
of protein responsiveness by multiple biochemical modification, regardless of
the type of adaptive response it induces. Therefore hierarchical biochemical processes
such as methylation and phosphorylation are natural candidates to induce this
property in signaling systems.

text: Maximally stable component detection is a very popular method for feature
analysis in images, mainly due to its low computation cost and high repeatability.
With the recent advance of feature-based methods in geometric shape analysis,
there is significant interest in finding analogous approaches in the 3D world.
In this paper, we formulate a diffusion-geometric framework for stable component
detection in non-rigid 3D shapes, which can be used for geometric feature detection
and description. A quantitative evaluation of our method on the SHREC’10 feature
detection benchmark shows its potential as a source of high-quality features.

text: "Natural objects can be subject to various transformations yet still preserve
properties that we refer to as invariants. Here, we use definitions of affine-invariant
arclength for surfaces in \r\n in order to extend the set of existing non-rigid
shape analysis tools. We show that by re-defining the surface metric as its equi-affine
version, the surface with its modified metric tensor can be treated as a canonical
Euclidean object on which most classical Euclidean processing and analysis tools
can be applied. The new definition of a metric is used to extend the fast marching
method technique for computing geodesic distances on surfaces, where now, the
distances are defined with respect to an affine-invariant arclength. Applications
of the proposed framework demonstrate its invariance, efficiency, and accuracy
in shape analysis."
