DESCRIPTION:Title: T
he eigenvalues of one-particle Dirac operator with general charge distribu
tions\nby Mathieu Lewin as part of Munich-Copenhagen-Santiago Mathemat
ical Physics seminar\n\n\nAbstract\nFor heavy atoms and molecules\, relati
vistic effects have to be taken into account. The most precise option is t
o use the Dirac operator\, but it is then notoriously difficult to include
Coulomb potentials\, which scale the same as the kinetic energy. In this
talk I will discuss one-particle Dirac operators with the potential induce
d by an arbitrary charge distribution. I will particularly focus on min-ma
x formulas for the eigenvalues and on an important conjecture about the op
timality of the first Dirac eigenvalue. If true\, this conjecture would ha
ve an impact on the shape of the potential energy surface of molecules in
Dirac theory.\n

DESCRIPTION:Title:
Random Schrödinger operators with complex decaying potentials\nby Kon
stantin Merz (TU Braunschweig) as part of Munich-Copenhagen-Santiago Mathe
matical Physics seminar\n\n\nAbstract\nEstimating the location and accumul
ation rate of eigenvalues of Schrödinger operators is a classical problem
in spectral theory and mathematical physics. The pioneering work of R. Fr
ank (Bull. Lond. Math. Soc.\, 2011) illustrated the power of Fourier analy
tic methods - like the uniform Sobolev inequality by Kenig\, Ruiz\, and So
gge\, or the Stein-Tomas restriction theorem - in this quest\, when the po
tential is non-real and has "short range".\n\nRecently S. Bögli and J.-C.
Cuenin (arXiv:2109.06135) showed that Frank's "short-range" condition is
in fact optimal\, thereby disproving a conjecture by A. Laptev and O. Safr
onov (Comm. Math. Phys.\, 2009) concerning Keller-Lieb-Thirring-type estim
ates for eigenvalues of Schrödinger operators with complex potentials.\n\
nIn this talk\, we estimate complex eigenvalues of continuum random Schrö
dinger operators of Anderson type. Our analysis relies on methods of J. Bo
urgain (Discrete Contin. Dyn. Syst.\, 2002\, Lecture Notes in Math.\, 2003
) related to almost sure scattering for random lattice Schrödinger operat
ors\, and allows us to consider potentials which decay almost twice as slo
wly as in the deterministic case.\n\nThe talk is based on joint work with
Jean-Claude Cuenin.\n

DESCRIPTION:Title:
Random band matrices in the localization regime\nby Peter Hislop (Univ
ersity of Kentucky) as part of Munich-Copenhagen-Santiago Mathematical Phy
sics seminar\n\n\nAbstract\nThe problem of determining the local eigenvalu
e statistics (LES) for one-dimensional random band matrices (RBM) will be
discussed with an emphasis on the localization regime. RBM are real symmet
ric $(2N+1)\\times(2N+1)$ matrices with nonzero entries in a band of width
$2N\\alpha+1$ about the diagonal\, for $0\\leq \\alpha \\leq 1$. The nonz
ero entries are independent\, identically distributed random variables. It
is conjectured that as $N\\rightarrow \\infty$ and for $0\\leq \\alpha <\
\frac{1}{2}$\, the LES is a Poisson point process\, whereas for $\\frac{1}
{2}<α≤1$\, the LES is the same as that for the Gaussian Orthogonal Ense
mble. This corresponds to a phase transition from a localized to a delocal
ized state as α passes through $\\frac{1}{2}$. In recent works with B. Br
odie and with M. Krishna\, we have made progress in proving this conjectur
e for $0\\leq \\alpha <\\frac{1}{2}$.\nSome of the results by others for t
he delocalized state with $\\frac{1}{2}<\\alpha≤1$\nwill also be describ
ed.\n

Adiabatic evolution of low-temperature many-body quantum systems\nby G
iovanna Marcelli (Aalborg University\, Denmark) as part of Munich-Copenhag
en-Santiago Mathematical Physics seminar\n\n\nAbstract\nWe consider finite
-range\, many-body fermionic lattice models and we study the evolution of
their thermal equilibrium state after introducing a weak and slowly varyin
g time-dependent perturbation. Under suitable assumptions on the external
driving\, we derive a representation for the average of the evolution of l
ocal observables via a convergent expansion in the perturbation\, for smal
l enough temperatures. Convergence holds for a range of parameters that is
uniform in the size of the system. Under a spectral gap assumption on the
unperturbed Hamiltonian\, convergence is also uniform in temperature. As
an application\, our expansion allows us to prove closeness of the time-ev
olved state to the instantaneous Gibbs state of the perturbed system\, in
the sense of expectation of local observables\, at zero and at small tempe
ratures. Our strategy is based on a rigorous version of the Wick rotation
and fermionic cluster expansion.\nThis talk is based on a joint work with
R. L. Greenblatt\, M. Lange and M. Porta.\n

\, when we do not assume smoothness of the coefficients. How do we then ob
tain sharp semiclassical spectral asymptotics? The main focus of this talk
will be to present the ideas in the proof of sharp semiclassical spectral

Negative spectrum of Schrödinger operators with oscillating potentials\nby Larry Read (LMU\, Germany) as part of Munich-Copenhagen-Santiago Mat

Hankel operators with band spectra and elliptic functions\nby Alexande
r Pushnitski (King's College London) as part of Munich-Copenhagen-Santiago
Mathematical Physics seminar\n\n\nAbstract\nI will discuss spectral prope
rties of bounded self-adjoint Hankel operators H\, realised as integral op
erators on the positive semi-axis\, that commute with dilations by a fixed
factor. In analogy with the spectral theory of periodic Schroedinger oper
ators\, the Hankel operators H of this class admit the Floquet-Bloch decom
position\, which represents H as a direct integral of certain compact fibe
r operators. As a consequence\, operators H have band spectra (the spectru
m of H is the union of disjoint intervals). A striking feature of this mod
el is that flat bands (i.e. intervals degenerating into points\, which are
eigenvalues of infinite multiplicity) may co-exist with non-flat bands\;
I will discuss some simple explicit examples of this nature. Key to the sp
ectral analysis of this class of Hankel operator is the theory of elliptic
functions\; I will explain this connection. This is joint work with Alexa
nder Sobolev (University College London). ArXiv link: https://arxiv.org/pd
