Phonon helicity induced by electronic Berry curvature in Dirac materials
Lun-Hui Hu, Jiabin Yu, Ion Garate +1
In two-dimensional insulators with time-reversal (TR) symmetry, a nonzero local Berry curvature of low-energy massive Dirac fermions can give rise to nontrivial spin and charge res…
Dynamical Fragile Topology in Floquet Crystals
Jiabin Yu, Yang Ge, Sankar Das Sarma
Although fragile topology has been intensely studied in static crystals in terms of Wannier obstruction, it is not clear how to generalize the concept to dynamical systems. In this…
Dynamical Symmetry Indicators for Floquet Crystals
Jiabin Yu, Rui-Xing Zhang, Zhi-Da Song
Various exotic topological phases of Floquet systems have been shown to arise from crystalline symmetries. Yet, a general theory for Floquet topology that is applicable to all crys…
Presence versus absence of Two-Dimensional Fermi Surface Anomalies
Donovan Buterakos, DinhDuy Vu, Jiabin Yu +1
We theoretically consider Fermi surface anomalies manifesting in the temperature dependent quasiparticle properties of two-dimensional (2D) interacting electron systems, comparing…
