A diabatic representation of the two lowest electronic states of Li3
Elham Nour Ghassemi, Jonas Larson, Asa Larson
Using the Multi-Reference Configuration Interaction method, the adiabatic potential energy surfaces of Li3 are computed. The two lowest electronic states are bound and exhibit a co…
Multiple-time-scale Landau-Zener transitions in many-body systems
Jonas Larson
Motivated by recent cold atom experiments in optical lattices, we consider a lattice version of the Landau-Zener problem. Every single site is described by a Landau-Zener problem,…
Impurity in a bosonic Josephson junction: swallowtail loops, chaos, self-trapping and the poor man's Dicke model
Jesse Mumford, Jonas Larson, D. H. J. O'Dell
We study a model describing identical bosonic atoms trapped in a double-well potential together with a single impurity atom, comparing and contrasting it throughout with the Di…
Integrability vs Quantum Thermalization
Jonas Larson
Non-integrability is often taken as a prerequisite for quantum thermalization. Still, a generally accepted definition of quantum integrability is lacking. With the basis in the dri…
Chaos in circuit QED: decoherence, localization, and nonclassicality
Jonas Larson, Duncan H. J. O'Dell
We study the open system dynamics of a circuit QED model operating in the ultrastrong coupling regime. If the resonator is pumped periodically in time the underlying classical syst…
XYZ quantum Heisenberg models with p-orbital bosons
Fernanda Pinheiro, Georg M. Bruun, Jani-Petri Martikainen +1
We demonstrate how the spin-1/2 XYZ quantum Heisenberg model can be realized with bosonic atoms loaded in the p band of an optical lattice in the Mott regime. The combination of Bo…
