Plasmon excitations in half-filled graphene: A Comparative study between Quantum Monte Carlo and Random Phase Approximation
Adrien Reingruber, Maksim Ulybyshev, 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…
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…
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…
The shear viscosity of interacting graphene
Kitinan Pongsangangan, Pedro Cosme, Emanuele Di Salvo +1
One of the hallmark properties of fluids is their shear viscosity which is, among other things, responsible for parabolic flow profiles through narrow channels. In recent years, th…
Hydrodynamics of charged two-dimensional Dirac systems II: the role of collective modes
Kitinan Pongsangangan, T. Ludwig, H. T. C. Stoof +1
We study the hydrodynamic properties of ultraclean interacting two-dimensional Dirac electrons with Keldysh quantum field theory. We study it from a weak-coupling and a strong-coup…
Hydrodynamics of charged two-dimensional Dirac systems I: thermo-electric transport
Kitinan Pongsangangan, T. Ludwig, H. T. C. Stoof +1
In this paper we study thermo-electric transport in interacting two-dimensional Dirac-type systems using a phenomenological Boltzmann approach. We consider a setup that can accommo…
Chiral symmetry breaking through spontaneous dimerization in kagomé metals
Riccardo Ciola, Kitinan Pongsangangan, Ronny Thomale +1
Due to an uprise in the variety of candidate compounds, kagome metals have recently gained significant attention. Among other features, kagome metals host Dirac cones as a key band…
Thermo-electric response in two-dimensional Dirac systems: the role of particle-hole pairs
Kitinan Pongsangangan, Simonas Grubinskas, Lars Fritz
Clean two-dimensional Dirac systems have received a lot of attention for being a prime candidate to observe hydrodynamical transport behavior in interacting electronic systems. Thi…
