We use relativistic ab initio methods combined with model Hamiltonian approaches to
analyze the normal-phase electronic and structural properties of the recently discovered WP …

The bismuth monolayer has recently been experimentally identified as a novel platform for
the investigation of two-dimensional single-element ferroelectric system. Here, we model the …

A Dirac fermion emerges as a result of interplay between symmetry and topology in
condensed matter. Current research moves towards investigating the Dirac fermions in the …

Correlated Dirac semimetal phases emerge in lightly doped (Tb-or La-doped) Mott insulator
Sr 2 Ir O 4, where ad-wave symmetry-breaking order underlying a pseudogap plays a crucial …

We implement the equation of motion of the large-N Gross-Neveu model from strong-
interaction physics in photonic waveguide arrays and study one of its paradigmatic …

We performed angle-resolved photoemission spectroscopy (ARPES) experiments on an
electron-doped Sr 2 RhO 4 system Sr 2− x Ce x RhO 4 in order to investigate the electron …

The room temperature ferromagnetic phase of the cubic antiperovskite Mn 3 ZnC is
suggested from first-principles calculation to be a nodal line Weyl semimetal. Features in the …

Based on first-principles density functional calculations, we report the existence of both
nontrivial band topology and superconductivity in three metallic Si allotropes, termed C mcm …

Topological materials are an exciting new area of inquiry. These materials exhibit
fundamentally new and nonlocal phenomena including spin-polarized surface states. More …
