text: "While Hartree–Fock theory is well established as a fundamental approximation
for interacting fermions, it has been unclear how to describe corrections to it
due to many-body correlations. In this paper we start from the Hartree–Fock state
given by plane waves and introduce collective particle–hole pair excitations.
These pairs can be approximately described by a bosonic quadratic Hamiltonian.
We use Bogoliubov theory to construct a trial state yielding a rigorous Gell-Mann–Brueckner–type
upper bound to the ground state energy. Our result justifies the random-phase
approximation in the mean-field scaling regime, for repulsive, regular interaction
potentials.\r\n"

text: We give a bound on the ground-state energy of a system of N non-interacting
fermions in a three-dimensional cubic box interacting with an impurity particle
via point interactions. We show that the change in energy compared to the system
in the absence of the impurity is bounded in terms of the gas density and the
scattering length of the interaction, independently of N. Our bound holds as long
as the ratio of the mass of the impurity to the one of the gas particles is larger
than a critical value m∗ ∗≈ 0.36 , which is the same regime for which we recently
showed stability of the system.

text: 'We consider an interacting, dilute Bose gas trapped in a harmonic potential
at a positive temperature. The system is analyzed in a combination of a thermodynamic
and a Gross–Pitaevskii (GP) limit where the trap frequency ω, the temperature
T, and the particle number N are related by N∼ (T/ ω) 3→ ∞ while the scattering
length is so small that the interaction energy per particle around the center
of the trap is of the same order of magnitude as the spectral gap in the trap.
We prove that the difference between the canonical free energy of the interacting
gas and the one of the noninteracting system can be obtained by minimizing the
GP energy functional. We also prove Bose–Einstein condensation in the following
sense: The one-particle density matrix of any approximate minimizer of the canonical
free energy functional is to leading order given by that of the noninteracting
gas but with the free condensate wavefunction replaced by the GP minimizer.'

text: We give a lower bound on the ground state energy of a system of two fermions
of one species interacting with two fermions of another species via point interactions.
We show that there is a critical mass ratio m2 ≈ 0.58 such that the system is
stable, i.e., the energy is bounded from below, for m∈[m2,m2−1]. So far it was
not known whether this 2 + 2 system exhibits a stable region at all or whether
the formation of four-body bound states causes an unbounded spectrum for all mass
ratios, similar to the Thomas effect. Our result gives further evidence for the
stability of the more general N + M system.

text: In this thesis we will discuss systems of point interacting fermions, their
stability and other spectral properties. Whereas for bosons a point interacting
system is always unstable this ques- tion is more subtle for a gas of two species
of fermions. In particular the answer depends on the mass ratio between these
two species. Most of this work will be focused on the N + M model which consists
of two species of fermions with N, M particles respectively which interact via
point interactions. We will introduce this model using a formal limit and discuss
the N + 1 system in more detail. In particular, we will show that for mass ratios
above a critical one, which does not depend on the particle number, the N + 1
system is stable. In the context of this model we will prove rigorous versions
of Tan relations which relate various quantities of the point-interacting model.
By restricting the N + 1 system to a box we define a finite density model with
point in- teractions. In the context of this system we will discuss the energy
change when introducing a point-interacting impurity into a system of non-interacting
fermions. We will see that this change in energy is bounded independently of the
particle number and in particular the bound only depends on the density and the
scattering length. As another special case of the N + M model we will show stability
of the 2 + 2 model for mass ratios in an interval around one. Further we will
investigate a different model of point interactions which was discussed before
in the literature and which is, contrary to the N + M model, not given by a limiting
procedure but is based on a Dirichlet form. We will show that this system behaves
trivially in the thermodynamic limit, i.e. the free energy per particle is the
same as the one of the non-interacting system.

text: We analyse the canonical Bogoliubov free energy functional in three dimensions
at low temperatures in the dilute limit. We prove existence of a first-order phase
transition and, in the limit (Formula presented.), we determine the critical temperature
to be (Formula presented.) to leading order. Here, (Formula presented.) is the
critical temperature of the free Bose gas, ρ is the density of the gas and a is
the scattering length of the pair-interaction potential V. We also prove asymptotic
expansions for the free energy. In particular, we recover the Lee–Huang–Yang formula
in the limit (Formula presented.).

text: The Bogoliubov free energy functional is analysed. The functional serves as
a model of a translation-invariant Bose gas at positive temperature. We prove
the existence of minimizers in the case of repulsive interactions given by a sufficiently
regular two-body potential. Furthermore, we prove the existence of a phase transition
in this model and provide its phase diagram.

text: Following an earlier calculation in 3D, we calculate the 2D critical temperature
of a dilute, translation-invariant Bose gas using a variational formulation of
the Bogoliubov approximation introduced by Critchley and Solomon in 1976. This
provides the first analytical calculation of the Kosterlitz-Thouless transition
temperature that includes the constant in the logarithm.

of the change in critical temperature to our attention. We also thank the Erwin

text: In this paper we define and study the classical Uniform Electron Gas (UEG),
a system of infinitely many electrons whose density is constant everywhere in
space. The UEG is defined differently from Jellium, which has a positive constant
background but no constraint on the density. We prove that the UEG arises in Density
Functional Theory in the limit of a slowly varying density, minimizing the indirect
Coulomb energy. We also construct the quantum UEG and compare it to the classical
UEG at low density.

text: 'The existence of a self-localization transition in the polaron problem has
been under an active debate ever since Landau suggested it 83 years ago. Here
we reveal the self-localization transition for the rotational analogue of the
polaron -- the angulon quasiparticle. We show that, unlike for the polarons, self-localization
of angulons occurs at finite impurity-bath coupling already at the mean-field
level. The transition is accompanied by the spherical-symmetry breaking of the
angulon ground state and a discontinuity in the first derivative of the ground-state
energy. Moreover, the type of the symmetry breaking is dictated by the symmetry
of the microscopic impurity-bath interaction, which leads to a number of distinct
self-localized states. The predicted effects can potentially be addressed in experiments
on cold molecules trapped in superfluid helium droplets and ultracold quantum
gases, as well as on electronic excitations in solids and Bose-Einstein condensates. '

text: We consider a model of fermions interacting via point interactions, defined
via a certain weighted Dirichlet form. While for two particles the interaction
corresponds to infinite scattering length, the presence of further particles effectively
decreases the interaction strength. We show that the model becomes trivial in
the thermodynamic limit, in the sense that the free energy density at any given
particle density and temperature agrees with the corresponding expression for
non-interacting particles.

text: We consider the dynamics of a large quantum system of N identical bosons in
3D interacting via a two-body potential of the form N3β-1w(Nβ(x - y)). For fixed
0 = β < 1/3 and large N, we obtain a norm approximation to the many-body evolution
in the Nparticle Hilbert space. The leading order behaviour of the dynamics is
determined by Hartree theory while the second order is given by Bogoliubov theory.

text: We study the ionization problem in the Thomas-Fermi-Dirac-von Weizsäcker theory
for atoms and molecules. We prove the nonexistence of minimizers for the energy
functional when the number of electrons is large and the total nuclear charge
is small. This nonexistence result also applies to external potentials decaying
faster than the Coulomb potential. In the case of arbitrary nuclear charges, we
obtain the nonexistence of stable minimizers and radial minimizers.

text: We prove that a system of N fermions interacting with an additional particle
via point interactions is stable if the ratio of the mass of the additional particle
to the one of the fermions is larger than some critical m*. The value of m* is
independent of N and turns out to be less than 1. This fact has important implications
for the stability of the unitary Fermi gas. We also characterize the domain of
the Hamiltonian of this model, and establish the validity of the Tan relations
for all wave functions in the domain.

text: We consider the Bogolubov–Hartree–Fock functional for a fermionic many-body
system with two-body interactions. For suitable interaction potentials that have
a strong enough attractive tail in order to allow for two-body bound states, but
are otherwise sufficiently repulsive to guarantee stability of the system, we
show that in the low-density limit the ground state of this model consists of
a Bose–Einstein condensate of fermion pairs. The latter can be described by means
of the Gross–Pitaevskii energy functional.

text: We consider Ising models in two and three dimensions, with short range ferromagnetic
and long range, power-law decaying, antiferromagnetic interactions. We let J be
the ratio between the strength of the ferromagnetic to antiferromagnetic interactions.
The competition between these two kinds of interactions induces the system to
form domains of minus spins in a background of plus spins, or vice versa. If the
decay exponent p of the long range interaction is larger than d + 1, with d
the space dimension, this happens for all values of J smaller than a critical
value Jc(p), beyond which the ground state is homogeneous. In this paper, we give
a characterization of the infinite volume ground states of the system, for pÂ
>Â 2d and J in a left neighborhood of Jc(p). In particular, we prove that the
quasi-one-dimensional states consisting of infinite stripes (d = 2) or slabs
(d = 3), all of the same optimal width and orientation, and alternating magnetization,
are infinite volume ground states. Our proof is based on localization bounds combined
with reflection positivity.

text: We study the time-dependent Bogoliubov–de-Gennes equations for generic translation-invariant
fermionic many-body systems. For initial states that are close to thermal equilibrium
states at temperatures near the critical temperature, we show that the magnitude
of the order parameter stays approximately constant in time and, in particular,
does not follow a time-dependent Ginzburg–Landau equation, which is often employed
as a phenomenological description and predicts a decay of the order parameter
in time. The full non-linear structure of the equations is necessary to understand
this behavior.
