Nonlinear thermal and thermoelectric transport from quantum geometry
Yuan Fang, Shouvik Sur, Yonglong Xie +1
Quantum geometry may enable the development of quantum phases ranging from superconductivity to correlated topological states. One powerful probe of quantum geometry is the nonline…
Fully nonequilibrium Hall response from Berry curvature
Shouvik Sur, Lei Chen, Yiming Wang +3
In topological materials, Berry curvature leads to intrinsic Hall responses. Focusing on time-reversal symmetric systems with broken inversion symmetry, a spontaneoous (zero magnet…
Dipolar Weyl semimetals
Alexander C. Tyner, Shouvik Sur
In time-reversal symmetry-broken Weyl semimetals, Weyl points act as monopoles and antimonopoles of the Berry curvature, with a monopole-antimonopole pair producing a net zero Berr…
Mixed-order topology of Benalcazar-Bernevig-Hughes models
Shouvik Sur, Alexander C. Tyner, Pallab Goswami
Benalcazar-Bernevig-Hughes (BBH) models, defined on -dimensional simple cubic lattice, are paradigmatic toy models for studying -th order topology and corner-localized, mid-g…
Topology of three-dimensional Dirac semimetals and generalized quantum spin Hall systems without gapless edge modes
Alexander C. Tyner, Shouvik Sur, Danilo Puggioni +2
Usually the quantum spin Hall states are expected to possess gapless, helical edge modes. Are there clean, non-interacting, quantum spin Hall states without gapless, edge modes? We…
