Hierarchy of timescales in a disordered spin-1/2 XX ladder
Kadir Çeven, L. Peinemann, F. Heidrich-Meisner, Phys. Rev. B 113, 045126 (2026).
Identified the timescales governing how a non-integrable quantum system relaxes to equilibrium, connecting spectral statistics to transport.
Neural-network quantum states for a two-leg Bose-Hubbard ladder under magnetic flux
Kadir Çeven, M. Ö. Oktel, A. Keleş, Phys. Rev. A 106, 063320 (2022).
Used a neural-network variational ansatz to compute phase diagrams for interacting bosons under a synthetic magnetic flux — a gauge-field setting related to topological cold-atom physics — matching state-of-the-art numerical methods.
