Bounds on quantum adiabaticity in driven many-body systems from generalized orthogonality catastrophe and quantum speed limit
Jyong-Hao Chen, Vadim Cheianov
We provide two inequalities for estimating adiabatic fidelity in terms of two other more handily calculated quantities, i.e., generalized orthogonality catastrophe and quantum spee…
Can we use heavy nuclei to detect relic neutrinos?
Oleksii Mikulenko, Yevheniia Cheipesh, Vadim Cheianov +1
Recent analysis of the viability of solid state-based relic neutrino detectors has revealed the fundamental necessity for the use of heavy, , -decayers as neutrino target…
Rapid-cycle Thouless pumping in a one-dimensional optical lattice
K. J. M. Schouten, V. Cheianov
An adiabatic cycle around a degeneracy point in the parameter space of a one-dimensional band insulator is known to result in an integer valued noiseless particle transport in the…
An ideal rapid-cycle Thouless pump
S. Malikis, V. Cheianov
Thouless pumping is a fundamental instance of quantized transport, which is topologically protected. Although its theoretical importance, the adiabaticity condition is an obstacle…
Navigating the pitfalls of relic neutrino detection
Yevheniia Cheipesh, Vadim Cheianov, Alexey Boyarsky
Beta-spectrum of radioactive atoms was long ago predicted to bear an imprint of the Cosmic Neutrino Background (CB). Over the years, it has been recognised that the best chance…
