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…
