About the Group
We are working out new understanding and methods allowing a quantitative description of complex interacting quantum systems, with a focus on collective effects in their dynamics
The group studies correlated quantum systems ranging from ultracold atoms to neutron stars, as well as basic models such as Hubbard lattices, Anderson impurity and Kondo model, etc. Equilibrium properties, steady state and quenched dynamics are investigated. Special attention is paid to the description of decoherence effects in qubit structures and manipulating of their properties by an external driving. We are collaborating with researchers from a number of universities including Hamburg, Vienna, Berlin, Geneve, London, Nijmegen, Skoltech, and Harvard university.
Our new sign-free QMC algorithm for driven bosonic system is a unique tool for numerically exact calculations of the dynamics at large time scale. We have pioneered in studying critical properties of the dynamical phase transition in an open system.
