Liouvillian topology and nonreciprocal dynamics in open Floquet chains
Florian Koch, Yu-Min Hu, Jan Carl Budich
Open quantum systems far from thermal equilibrium can exhibit remarkable physical phenomena including topological properties without a direct equilibrium counterpart. Along these l…
Advancing Stochastic 3-SAT Solvers by Dissipating Oversatisfied Constraints
J. Schwardt, J. C. Budich
We introduce and benchmark a stochastic local search heuristic for the NP-complete satisfiability problem 3-SAT that drastically outperforms existing solvers in the notoriously dif…
Quantum Hall Effect without Chern Bands
Benjamin Michen, Jan Carl Budich
The quantum Hall effect was originally observed in a two-dimensional electron gas forming Landau levels when exposed to a strong perpendicular magnetic field and was later generali…
Asymptotic Exceptional Steady States in Dissipative Dynamics
Yu-Min Hu, Jan Carl Budich
Spectral degeneracies in Liouvillian generators of dissipative dynamics generically occur as exceptional points, where the corresponding non-Hermitian operator becomes non-diagonal…
Probing Green's Function Zeros by Co-tunneling through Mott Insulators
Carl Lehmann, Lorenzo Crippa, Giorgio Sangiovanni +1
Quantum tunneling experiments have provided deep insights into basic excitations occurring as Green's function poles in the realm of complex quantum matter. However, strongly corre…
