Non-Hermitian Fabry-Perot Resonances in a PT-symmetric system
Ken Shobe, Keiichi Kuramoto, Ken-Ichiro Imura +1
In non-Hermitian scattering problems the behavior of the transmission probability is very different from its Hermitian counterpart; it can exceed unity or even be divergent, since…
Theory of non-equilibrium noise in general multi-terminal superconducting hydrid devices: application to multiple Cooper pair resonances
R. Jacquet, A. Popoff, K. -I. Imura +5
We consider the out-of-equilibrium behavior of a general class of mesoscopic devices composed of several superconducting or/and normal metal leads separated by quantum dots. Starti…
Generalized Bloch band theory for non-Hermitian bulk-boundary correspondence
Ken-Ichiro Imura, Yositake Takane
Bulk-boundary correspondence is the cornerstone of topological physics. In some non-Hermitian topological system this fundamental relation is broken in the sense that the topologic…
Finite-size effects in cylindrical topological insulators
Michele Governale, Bibek Bhandari, Fabio Taddei +2
We present a theoretical study of a nanowire made of a three-dimensional topological insulator. The bulk topological insulator is described by a continuum-model Hamiltonian, and th…
