text: We study the time evolution of the Nelson model in a mean-field limit in which
N nonrelativistic bosons weakly couple (with respect to the particle number) to
a positive or zero mass quantized scalar field. Our main result is the derivation
of the Bogoliubov dynamics and higher-order corrections. More precisely, we prove
the convergence of the approximate wave function to the many-body wave function
in norm, with a convergence rate proportional to the number of corrections taken
into account in the approximation. We prove an analogous result for the unitary
propagator. As an application, we derive a simple system of partial differential
equations describing the time evolution of the first- and second-order approximations
to the one-particle reduced density matrices of the particles and the quantum
field, respectively.

text: "It is a remarkable property of BCS theory that the ratio of the energy gap
at zero temperature Ξ\r\n and the critical temperature Tc is (approximately) given
by a universal constant, independent of the microscopic details of the fermionic
interaction. This universality has rigorously been proven quite recently in three
spatial dimensions and three different limiting regimes: weak coupling, low density
and high density. The goal of this short note is to extend the universal behavior
to lower dimensions d=1,2 and give an exemplary proof in the weak coupling limit."

text: We first review the problem of a rigorous justification of Kubo’s formula
for transport coefficients in gapped extended Hamiltonian quantum systems at zero
temperature. In particular, the theoretical understanding of the quantum Hall
effect rests on the validity of Kubo’s formula for such systems, a connection
that we review briefly as well. We then highlight an approach to linear response
theory based on non-equilibrium almost-stationary states (NEASS) and on a corresponding
adiabatic theorem for such systems that was recently proposed and worked out by
one of us in [51] for interacting fermionic systems on finite lattices. In the
second part of our paper, we show how to lift the results of [51] to infinite
systems by taking a thermodynamic limit.

text: Hartree–Fock theory has been justified as a mean-field approximation for fermionic
systems. However, it suffers from some defects in predicting physical properties,
making necessary a theory of quantum correlations. Recently, bosonization of many-body
correlations has been rigorously justified as an upper bound on the correlation
energy at high density with weak interactions. We review the bosonic approximation,
deriving an effective Hamiltonian. We then show that for systems with Coulomb
interaction this effective theory predicts collective excitations (plasmons) in
accordance with the random phase approximation of Bohm and Pines, and with experimental
observation.

text: In this paper we describe an intrinsically geometric way of producing magnetic
fields on S3 and R3 for which the corresponding Dirac operators have a non-trivial
kernel. In many cases we are able to compute the dimension of the kernel. In particular
we can give examples where the kernel has any given dimension. This generalizes
the examples of Loss and Yau [1].
