Non-Hermitian Landau Levels
Anton Montag, Tomoki Ozawa
We formulate non-Hermitian Landau levels in two-dimensional systems under a complex perpendicular magnetic field. In the symmetric gauge, we derive their discretely spaced, highly…

Quantum geometrical effects in non-Hermitian systems
Anton Montag, Tomoki Ozawa
We explore the relation between quantum geometry in non-Hermitian systems and physically measurable phenomena. We highlight various situations in which the behavior of a non-Hermit…

Geometric contribution to adiabatic amplification in non-Hermitian systems
Tomoki Ozawa, Henning Schomerus
Concepts from non-Hermitian quantum mechanics have proven useful in understanding and manipulating a variety of classical systems, such as those encountered in optics, classical me…
