Covariant formulation of the Berry connection in non-Hermitian systems
Ievgen I. Arkhipov
Non-Hermitian systems exhibit spectral and topological phenomena absent in Hermitian physics; however, their geometric characterization remains subtle due to the intrinsic ambiguit…
Observation of Restored Adiabatic State Transfer in Time-Modulated Non-Hermitian Systems
Xiaowei Wang, Ievgen I. Arkhipov, Quan Lin +5
Exceptional points (EPs) have attracted extensive research interest due to their intriguing properties. One of the hallmarks of EP physics is that dynamically encircling the EPs in…
Achieving the Quantum Fisher Information Bound in Pseudo-Hermitian Sensors
Ievgen I. Arkhipov, Franco Nori, Åahin K. Ãzdemir
Non-Hermitian systems have attracted considerable interest over the last few decades due to their unique spectral and dynamical properties not encountered in Hermitian counterparts…
Topological state permutations in time-modulated non-Hermitian multiqubit systems with suppressed non-adiabatic transitions
Ievgen I. Arkhipov, Philippe Lewalle, Franco Nori +2
Non-Hermitian systems have been at the center of intense research for over a decade, partly due to their nontrivial energy topology formed by intersecting Riemann manifolds with br…
How to realize compact and non-compact localized states in disorder-free hypercube networks
Ievgen I. Arkhipov, Fabrizio Minganti, Franco Nori
We present a method for realizing various zero-energy localized states on disorder-free hypercube graphs. Previous works have already indicated that disorder is not essential for o…
