On the left, typical energy spectra for 1D non-Hermitian systems under periodic or open boundary conditions appear as loops (blue) with spectral windings and arcs (red). On the right, energy spectra ...

We study spectral statistics in spatially extended chaotic quantum many-body systems, using simple 1D lattice Floquet models without time-reversal symmetry. Computing the spectral form factor K(t) ...
