Multi-critical Behavior in Topological Phase Transitions
S. Rufo, Nei Lopes, Mucio A. Continentino +1
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 consequenc…
Bosonic Dirac Materials on a honeycomb antiferromagnetic Ising model
Griffith M. A. R., S. Rufo, Minos A. Neto
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…
Finite Size Effects in Topological Quantum Phase Transitions
Mucio A. Continentino, Sabrina Rufo, Griffith M. Rufo
The interest in the topological properties of materials brings into question the problem of topological phase transitions. As a control parameter is varied, one may drive a system…
