Emergent non-Hermitian boundary contributions to charge pumping and electric polarization
K. Kyriakou, K. Moulopoulos
The phenomenon of charge pumping and the modern theory of electric polarization are reconsidered by analytically taking into account emergent non-Hermitian contributions. These are…
Orbital Magnetization in Solids: Boundary contributions as a non-Hermitian effect
K. Kyriakou, K. Moulopoulos
The theory of orbital magnetization is reconsidered by defining additional quantities that incorporate a non-Hermitian effect due to anomalous operators that break the domain of de…
Emergent non-Hermitian contributions to the Ehrenfest and Hellmann-Feynman theorems
Georgios Konstantinou, Kyriakos Kyriakou, Konstantinos Moulopoulos
We point out that two of the most important theorems of Quantum Mechanics, the Ehrenfest theorem and the Hellmann-Feynman theorem, lack in their standard form important information…
Dynamical extension of Hellmann-Feynman theorem and application to nonadiabatic quantum processes in Topological and Correlated Matter
Kyriakos Kyriakou, Konstantinos Moulopoulos
An extension of the Hellmann-Feynman theorem to one employing dynamical parameters that vary with time according to quantum dynamics is rigorously derived, avoiding any linear resp…
Arbitrary mixture of two charged interacting particles in a magnetic Aharonov-Bohm ring: persistent currents and Berry's phases
Kyriakos Kyriakou, Konstantinos Moulopoulos, Areg Ghazaryan +1
Aharonov-Bohm Physics at the two-particle level is investigated for distinguishable interacting charged particles through the exact solution of a toy model with confined states. Th…
