The effect of Coulomb interactions on relic neutrino detection via beta decaying impurities in (semi)metals
Karel van der Marck, Vadim Cheianov
Measuring the electron neutrino mass is a long-standing objective and requires a high energy resolution of certain -decay experiments, as well as a visible cosmic neutrino back…
Sensitivity of the spectral form factor to short-range level statistics
Wouter Buijsman, Vadim Cheianov, Vladimir Gritsev
The spectral form factor is a dynamical probe for level statistics of quantum systems. The early-time behaviour is commonly interpreted as a characterization of two-point correlati…
Gumbel statistics for entanglement spectra of many-body localized eigenstates
Wouter Buijsman, Vladimir Gritsev, Vadim Cheianov
An entanglement spectrum encodes statistics beyond the entanglement entropy, of which several have been studied in the context of many-body localization. We numerically study the e…
Quantum adiabaticity in many-body systems and almost-orthogonality in complementary subspace
Jyong-Hao Chen, Vadim Cheianov
We investigate why, in quantum many-body systems, the adiabatic fidelity and the overlap between the initial state and instantaneous ground states often yield nearly identical valu…
