Nonperturbative computation of thermal conductivity based on Path Integral Monte Carlo methods

Vladislav Efremkin, Stefano Mossa, Jean-Louis Barrat +1

The calculation of thermal conductivity in insulating solids at temperatures below the Debye temperature is problematic, due to the breakdown of classical and semi-classical approa…

Neural Wave Functions for High-Pressure Atomic Hydrogen

David Linteau, Saverio Moroni, Giuseppe Carleo +1

We leverage the power of neural quantum states to describe the ground state wave function of solid and liquid atomic hydrogen, including both electronic and protonic degrees of fre…

Approximation of magnetic SchrÃ¶dinger operators with $I^´$ -interactions supported on networks

Markus Holzmann

This paper deals with the approximation of a magnetic SchrÃ¶dinger operator with a singular $I^´$ -potential that is formally given by $(i \nabla + A)^{2} + Q + I^\pm I^´_{I^} £$ by SchrÃ¶dinge…

Weak coupling for SchrÃ¶dinger operators with complex potentials

Jussi Behrndt, Markus Holzmann, Petr Siegl +1

We study the discrete eigenvalues emerging from the threshold of the essential spectrum of one or two-dimensional SchrÃ¶dinger operators with complex-valued $L^{p}$ -potentials in a…

Jussi Behrndt, Markus Holzmann, Christian Stelzer-Landauer

This paper is devoted to the approximation of two and three-dimensional Dirac operators $H_{V I^´_{I^} £}$ with combinations of electrostatic and Lorentz scalar $I^´$ -shell i…

Jussi Behrndt, Markus Holzmann, Christian Stelzer

In this paper the approximation of Dirac operators with general $I^´$ -shell potentials supported on $C^{2}$ -curves in $R^{2}$ or $C^{2}$ -surfaces in $R^{3}$ , which may be…
