DOI: 10.1038/s41467-020-16871-9
Abstract: A state of matter with a multi-component order parameter can give rise to vestigial order. In the vestigial phase, the primary order is only partially melted, leaving a remaining symmetry breaking behind, an effect driven… read more here.

DOI: 10.1103/physrevb.100.104518
Abstract: Proximity induced superconducting states in the surface of magnetically doped topological insulators can host chiral Majorana modes. We consider a Josephson junction in that system with changing the chemical potential, which drives a topological phase… read more here.

Abstract: The quantum anomalous Hall effect (QAHE) has been experimentally observed in magnetically doped topological insulators at ultralow temperatures. Inhomogeneous ferromagnetism is considered to be one of the main factors that lead to the unexpected low… read more here.

DOI: 10.1103/physrevb.97.085151
Abstract: We report magnetotransport measurements on magnetically doped (Bi,Sb)$_2$Te$_3$ films grown by molecular beam epitaxy. In Hallbar devices, logarithmic dependence on temperature and bias voltage are obseved in both the longitudinal and anomalous Hall resistance. The… read more here.
