Influence of interactions on the chiral effect in Dirac semimetal
Maksim Ulybyshev, M. A. Zubkov
We consider the 1D Su-Schrieffer-Heeger (SSH) model. It was recently shown that, for the noninteracting model in its Dirac semimetal phase, the linear response of the axial charge…
Strain-Tuned Incommensurate Kekulé Spiral Order in Twisted Bilayer Graphene: a Quantum Many-Body Study
Cheng Huang, Yves H. Kwan, Maksim Ulybyshev +3
The understanding of quantum many-body states in twisted bilayer graphene at the magic angle has been greatly improved both in experiment and in theory. However, away from the exac…
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…
Angle-Tuned Gross-Neveu Quantum Criticality in Twisted Bilayer Graphene: A Quantum Monte Carlo Study
Cheng Huang, Nikolaos Parthenios, Maksim Ulybyshev +4
The fascinating quantum many-body states in twisted bilayber graphene (TBG) at magic angle, due to the interplay of Coulomb interactions and the quantum metrics of flat bands, have…
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…
