Chirped Bloch-Harmonic oscillations in a parametrically forced optical lattice
Usman Ali, Martin Holthaus, Torsten Meier
The acceleration theorem for wavepacket propagation in periodic potentials disentangles the kspace dynamics and real-space dynamics. This is well known and understood for Bloch osc…
Following Floquet states in high-dimensional Hilbert spaces
Nils Krüger, Martin Holthaus
An iterative algorithm is established which enables one to compute individual Floquet states even for many-body systems with high-dimensional Hilbert spaces that are not accessible…
Environment-controlled Floquet-state paramagnetism
Onno R. Diermann, Heinz-Jürgen Schmidt, Jürgen Schnack +1
We study the response of ideal spin systems which are interacting with both a strong oscillating magnetic field, and a thermal environment, to a weak probing magnetic field. We dem…
Quantum critical properties of Bose-Hubbard models
Sören Sanders, Martin Holthaus
The Mott insulator-to-superfluid transition exhibited by the Bose-Hubbard model on a two-dimensional square lattice occurs for any value of the chemical potential, but becomes crit…
Floquet-state cooling
Onno R. Diermann, Martin Holthaus
We demonstrate that a periodically driven quantum system can adopt a quasistationary state which is effectively much colder than a thermal reservoir it is coupled to, in the sense…
Periodic thermodynamics of the parametrically driven harmonic oscillator
Onno R. Diermann, Helge Frerichs, Martin Holthaus
We determine the quasistationary distribution of Floquet-state occupation probabilities for a parametrically driven harmonic oscillator coupled to a thermal bath. Since the system…
