Noise probing of topological band gaps in dispersionless quantum states
Alexander Kruchkov, Shinsei Ryu
We uncover a useful connection between the integrated current noise and the topological band gap in dispersionless quantum states, $\int d ω[ \mathcal S^{\text{flat}}_{xx} +…
Unconventional superfluidity and quantum geometry of topological bosons
Ilya Lukin, Andrii Sotnikov, Alexander Kruchkov
We investigate superfluidity of bosons in gapped topological bands and discover a new phase that has no counterparts in the previous literature. This phase is characterized by a hi…
Anomalous conductivity of -symmetric Fermi liquids
Alexander Kruchkov
We consider a non-Hermitian yet -symmetric Fermi liquid (-FL) in external electric fields. Due to -symmetry, the system exhibits real spec…
Radiation spectrum of systems with condensed light
Alex Kruchkov
Experimental observation of Bose-Einstein condensation (BEC) of photons inside a microcavity induced an extensive study of the phenomenon. Beyond the purely theoretical interest, t…
