Abstract A proposal to study topological models beyond the standard topological classification and that exhibit breakdown of Lorentz invariance is presented. The focus of the investigation relies on their anisotropic quantum critical behavior. We stu

The ground state magnetic properties of the J 1 − J 1 ′ − J 2 spin- 1 ∕ 2 Heisenberg antiferromagnetic model with exchange anisotropies is studied on the square lattice. Independent exchange anisotropies are included for first and second neig

Topological phase transitions can be described by the theory of critical phenomena and identified by critical exponents that define their universality classes. This is a consequence of the existence of a diverging length at the transition that has be

Motivated by the recent proposal of Bosonic Dirac materials (BDM), we revisited the Ising model on a honeycomb lattice in the presence of the longitudinal and transverse fields. We apply linear spin-wave theory to obtain the magnon dispersion and its
