Abstract: For a large class of dynamical systems, the optimally time-dependent (OTD) modes, a set of deformable orthonormal tangent vectors that track directions of instabilities along any trajectory, are known to depend "pointwise" on the state… read more here.

Abstract: We analyze a correlated system in equilibrium with special emphasis on non-Hermitian topology inducing a skin effect. The pseudospectrum, computed by the real-space dynamical mean field theory, elucidates that additional pseudoeigenstates emerge for the open… read more here.
