One of the intriguing properties characteristic to three-dimensional topological materials is
the topological magnetoelectric phenomena arising from a topological term called the θ …

We determine the phase diagram of the Kane-Mele model with a long-range Coulomb
interaction using an exact quantum Monte Carlo method. Long-range interactions are …

We show that a Wilson-type discretization of the Gross–Neveu model, a fermionic N-flavor
quantum field theory displaying asymptotic freedom and chiral symmetry breaking, can …

A sufficiently strong long-range Coulomb interaction can induce excitonic pairing in gapless
Dirac semimetals, which generates a finite gap and drives the semimetal-insulator quantum …

We study the effects of strong 1/r long-range Coulomb interactions in a Weyl semimetal. We
consider a three-dimensional (3D) Dirac fermion system on a lattice with a time-reversal …

We study the stability of Dirac semimetals with N nodes in three spatial dimensions against
strong 1/r long-range Coulomb interactions. We particularly study the cases of N= 4 and N …

We report on the mean-field study of the chiral magnetic effect (CME) in static magnetic
fields within a simple model of parity-breaking Weyl semimetal given by the lattice Wilson …

We review the application of lattice QCD techniques, most notably the Hybrid Monte Carlo
(HMC) simulations, to first-principle study of tight-binding models of crystalline solids with …

The phenomenon of particle production for quantum field theories in curved spacetimes is
crucial to understand the large-scale structure of a universe from an inflationary epoch. In …

The phase structure of two-dimensional topological insulators under a sufficiently strong
electron-electron interaction is investigated. The effective theory is constructed by extending …
