First Passage Problem: Asymptotic Corrections due to Discrete Sampling
Lars Fritz
How long a stochastic process survives before leaving a domain depends not only on its intrinsic dynamics but also on how it is observed. Classical first-passage theory assumes con…
Hydrodynamics in generalized electronic two-band systems
E. Di Salvo, P. Cosme, L. Fritz
In this paper, we derive the Euler and Navier-Stokes equations for electronic two-band systems in arbitrary dimension and with generic power-law dispersion relations. We focus on t…
Bulk Hydrodynamic Transport in Weyl Semimetals
Joan Bernabeu, Kitinan Pongsangangan, H. T. C. Stoof +1
The role of collective longitudinal modes, plasmons, in bulk hydrodynamic transport in Weyl semimetals is explored. In contrast to graphene, where these modes are gapless, plasmons…
Topological phases of the interacting Su-Schrieffer-Heeger model: An analytical study
E. Di Salvo, A. Moustaj, C. Xu +4
The interacting SSH model provides an ideal ground to study the interplay between topologically insulating phases and electron-electron interactions. We study the polarization dens…
Classification of mass terms in kagome semimetals
Simone Ciceri, Matteo Massaro, Lars Fritz
In the last years, kagome materials received massive attention by virtue of being candidate hosts for a large variety of quantum phases: spin liquids, unconventional superconductiv…
