Quantum geometry in the dynamics of band-projected operators
Chen Xu, Andreas Haller, Suraj Hegde +2
We study the dynamics of electrons in crystalline solids in the presence of inhomogeneous external electric and magnetic fields. We present a manifestly gauge-invariant operator-ba…
Chiral damping with persistent edge states: interplay of spectral topology and band topology in open quantum systems
Ronika Sarkar, Suraj S. Hegde, Awadhesh Narayan +1
We study the dynamical consequences of combining the non-Hermitian skin effect with topological edge states. Focusing on the paradigmatic dissipative Hofstadter model, we find that…
Giant quantum oscillations in thermal transport in low-density metals via electron absorption of phonons
B. Bermond, R. Wawrzynczak, S. Zherlitsyn +14
Oscillations of conductance observed in strong magnetic fields are a striking manifestation of the quantum dynamics of charge carriers in solids. The large charge carrier density i…
Nonlinear response functions and disorder: the case of photogalvanic effect
Konstantinos Ladovrechis, Tobias Meng
We investigate the impact of disorder in the form of impurity scattering on a generalized version of the circular photogalvanic effect (CPGE) in Weyl semimetals where the frequency…
Unconventional Hall response in the quantum limit of HfTe5
S. Galeski, X. Zhao, R. Wawrzyńczak +14
Interacting electrons confined to their lowest Landau level in a high magnetic field can form a variety of correlated states, some of which manifest themselves in a Hall effect. Al…
