Spectral functions of the honeycomb lattice with both the Hubbard and long-range Coulomb Interactions
Ho-Kin Tang, Indra Yudhistira, Udvas Chattopadhyay +4
The absence of screening of the non-local Coulomb interaction in Dirac systems at charge neutrality leads to the breakdown of the Fermi liquid and divergence of the Fermi velocity.…
Engineering many-body quantum Hamiltonians with non-ergodic properties using quantum Monte Carlo
Nyayabanta Swain, Ho-Kin Tang, Darryl Chuan Wei Foo +5
We present a computational framework to identify Hamiltonians of interacting quantum many-body systems that host non-ergodic excited states. We combine quantum Monte Carlo simulati…
Response to Comment on "The role of electron-electron interactions in two-dimensional Dirac fermions"
Ho-Kin Tang, J. N. Leaw, J. N. B. Rodrigues +4
Hesselmann {\it et al}.~question one of our conclusions, namely, the suppression of Fermi velocity at the Gross-Neveu critical point for the specific case of vanishing long-range i…
Interaction driven metal-insulator transition in strained graphene
Ho-Kin Tang, E. Laksono, J. N. B. Rodrigues +3
The question of whether electron-electron interactions can drive a metal to insulator transition in graphene under realistic experimental conditions is addressed. Using three repre…
