Emergent topological quantum orbits in the charge density wave phase of kagome metal CsVSb
Hengxin Tan, Yongkang Li, Yizhou Liu +3
The recently discovered kagome materials VSb ( = K, Rb, Cs) attract intense research interest in intertwined topology, superconductivity, and charge density waves (CD…
General nonlinear Hall current in magnetic insulators beyond the quantum anomalous Hall effect
Daniel Kaplan, Tobias Holder, Binghai Yan
Can a generic magnetic insulator exhibit a Hall current? The quantum anomalous Hall effect (QAHE) is one example of an insulating bulk carrying a quantized Hall conductivity and ot…
Momentum-inversion symmetry breaking on the Fermi surface of magnetic topological insulators
Hengxin Tan, Daniel Kaplan, Binghai Yan
Magnetic topological insulators (MnBiTe)(BiTe) were anticipated to exhibit magnetic energy gaps while recent spectroscopic studies did not observe them. Thus, m…
Twisted photovoltaics at terahertz frequencies from momentum shift current
Daniel Kaplan, Tobias Holder, Binghai Yan
The bulk photovoltaic effect (BPVE) converts light into a coherent dc current at zero bias, through what is commonly known as the shift current. This current has previously been at…
Nonvanishing sub-gap photocurrent as a probe of lifetime effects
Daniel Kaplan, Tobias Holder, Binghai Yan
For semiconductors and insulators, it is commonly believed that in-gap transitions into non-localized states are smoothly suppressed in the clean limit, i.e. at zero temperature th…
Consequences of Time-reversal-symmetry Breaking in the Light-Matter Interaction: Berry Curvature, Quantum Metric and Diabatic Motion
Tobias Holder, Daniel Kaplan, Binghai Yan
Nonlinear optical response is well studied in the context of semiconductors and has gained a renaissance in studies of topological materials in the recent decade. So far it mainly…
High Temperature Superconductivity: A Simple Model Exploiting Hydrogen Bonds
Daniel Kaplan, Yoseph Imry
Lately, there has been much interest in high temperature superconductors, and more recently hydrogen-based superconductors. This work offers a simple model which explains the behav…
