Nonlinear quantum Kibble-Zurek ramps in open systems at finite temperature
Johannes N. Kriel, Emma C. King, Michael Kastner
We analyze quantum systems under a broad class of protocols in which the temperature and a Hamiltonian control parameter are ramped simultaneously and, in general, in a nonlinear f…

Generating Generalised Ground-State Ansatzes from Few-Body Examples
Matt Lourens, Ilya Sinayskiy, Johannes N. Kriel +1
We introduce a method that generates ground-state ansatzes for quantum many-body systems which are both analytically tractable and accurate over wide parameter regimes. Our approac…
