Quantum geometry in many-body systems with precursors of criticality
Jan Střeleček, Pavel Cejnar
We analyze the geometry of the ground-state manifold in parameter-dependent many-body systems with quantum phase transitions (QPTs) and describe finite-size precursors of the singu…
Analytic approach to the Landau-Zener problem in bounded parameter space
Felipe Matus, Jan Střeleček, Pavel Cejnar
Three analytic solutions to the Schrödinger equation for the time-dependent Landau-Zener Hamiltonian are presented. They correspond to specific finite-time driving paths in a bound…
Decoherence-assisted quantum driving
Pavel Cejnar, Pavel Stránský, Jan Střeleček +1
We propose a protocol for transitionless driving of a bound quantum system in its parameter space using repeated measurement-like interactions with an external spectator system. As…
Search for optimal driving in finite quantum systems with precursors of criticality
Felipe Matus, Jan Střeleček, Pavel Stránský +1
Using the adiabatic perturbation theory of driven dynamics [Phys. Rev. A 78, 052508 (2008)] we design a hierarchy of quantum state preparation protocols that systematically increas…
