Non-equilibrium nano physics

Physical phenomena occur in general under non-equilibrium conditions, because of time-dependence, influence from external force fields, and local variations in the environment. Measurements intrinsically invoke disturbances which give rise to fluctuations that may or may not be desired. Our task is to develop new theoretical framework for studies of dynamical aspects of correlated materials and apply it to address properties of concrete systems.

Developments of new theoretical framework for studies of dynamical aspects of correlated materials under non-equilibrium conditions is one of our central tasks. The primary focus is on fundamental mechanisms for couplings between electronic and internal degrees of freedom, which may be of, e.g., magnetic, electric, and mechanical nature, and they may be coupled effectively through the electronic structure. It is crucial to deeply analyse the importance of those interactions in the bigger picture, since they may dramatically influence the physical dynamics. Of great importance is testing our developments to applications to address properties of concrete systems. For instance, we study dynamical magnetic exchange interactions between magnetic molecules, electric and thermal field control of magnetic exchange interactions. Also vibrationally induced superconductivity in graphene and topological insulators, novel magnetic textures induced by vibrational defects in topological superconductors, remote control of dynamical quantum interference, among others.
