Scaling behavior in a multicritical one-dimensional topological insulator
M. Malard, H. Johannesson, W. Chen
A class of Aubry-André-Harper models of spin-orbit coupled electrons exhibits a topological phase diagram where two regions belonging to the same phase are split up by a multicriti…

Fidelity susceptibility near topological phase transitions in quantum walks
S. Panahiyan, W. Chen, S. Fritzsche
The notion of fidelity susceptibility, introduced within the context of quantum metric tensor, has been an important quantity to characterize the criticality near quantum phase tra…

Unifying topological phase transitions in noninteracting, interacting, and periodically driven systems
Paolo Molignini, R. Chitra, Wei Chen
Topological phase transitions track changes in topological properties of a system and occur in real materials as well as quantum engineered systems, all of which differ greatly in…
