Husimi dynamics generated by non-Hermitian Hamiltonians
Katherine Holmes, Wasim Rehman, Simon Malzard +1
The dynamics generated by non-Hermitian Hamiltonians are often less intuitive than those of conventional Hermitian systems. Even for models as simple as a complexified harmonic osc…
Semiclassical Husimi distributions for non-Hermitian quantum systems
Joseph Hall, Simon Malzard, Eva-Maria Graefe
We construct a semiclassical phase-space density of Schur vectors in non-Hermitian quantum systems. Each Schur vector is associated to a single Planck cell. The Schur states are or…
Landau-Zener transitions through a pair of higher order exceptional points
Rishindra Melanathuru, Simon Malzard, Eva-Maria Graefe
Non-Hermitian quantum systems with explicit time dependence are of ever-increasing importance. There are only a handful of models that have been analytically studied in this contex…
Nonhermitian defect states from lifetime differences
Martí Bosch, Simon Malzard, Martina Hentschel +1
Nonhermitian systems provide new avenues to create topological defect states. An unresolved general question is how much the formation of these states depends on asymmetric backsca…
Nonlinear mode competition and symmetry-protected power oscillations in topological lasers
Simon Malzard, Henning Schomerus
Topological photonics started out as a pursuit to engineer systems that mimic fermionic single-particle Hamiltonians with symmetry-protected modes, whose number can only change in…
Bulk and edge-state arcs in non-hermitian coupled-resonator arrays
Simon Malzard, Henning Schomerus
We describe the formation of bulk and edge arcs in the dispersion relation of two-dimensional coupled-resonator arrays that are topologically trivial in the hermitian limit. Each r…
