Comparative study of plasmons in half-filled graphene via Quantum Monte Carlo and Random Phase Approximation
Maksim Ulybyshev, Adrien Reingruber, Kitinan Pongsangangan
Transport properties of strongly correlated materials have contributions from quasiparticle excitations such as electrons and holes as well as emerging collective excitations such…
Kinetic equation from Landau level basis: Beyond relaxation-time approximation
Kitinan Pongsangangan
The purpose of this paper is to formulate a kinetic theory describing transport properties of electrons in a uniform magnetic field of arbitrary magnitude. Exposing an electronic s…
Hydrodynamics of particle-hole symmetric systems: a quantum Monte Carlo study
Adrien Reingruber, Kitinan Pongsangangan, Fakher Assaad +1
The emergence of hydrodynamic behavior in electronic flow within clean, particle-hole-symmetric systems at half-filling is a non-trivial problem. Navier-Stokes (NS) equations descr…
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…
