Non-equilibrium Effects in Dissipative Strongly Correlated Systems
Jiajun Li
Novel physics arises when strongly correlated system is driven out of equilibrium by external fields. Dramatic changes in physical properties, such as conductivity, are empirically…
Quantum to classical crossover of Floquet engineering in correlated quantum systems
Michael A. Sentef, Jiajun Li, Fabian Künzel +1
Light-matter coupling involving classical and quantum light offers a wide range of possibilities to tune the electronic properties of correlated quantum materials. Two paradigmatic…
Electromagnetic coupling in tight-binding models for strongly correlated light and matter
Jiajun Li, Denis Golez, Giacomo Mazza +3
We discuss the construction of low-energy tight-binding Hamiltonians for condensed matter systems with a strong coupling to the quantum electromagnetic field. Such Hamiltonians can…
Superconducting optical response of photodoped Mott insulators
Jiajun Li, Denis Golez, Philipp Werner +1
Ultrafast laser pulses can redistribute charges in Mott insulators on extremely short time scales, leading to the fast generation of photocarriers. It has recently been demonstrate…
Revealing Hund's multiplets in Mott insulators under strong electric fields
Nagamalleswararao Dasari, Jiajun Li, Philipp Werner +1
We investigate the strong-field dynamics of a paramagnetic two-band Mott insulator using real-time dynamical mean-field theory. A dielectric breakdown occurs due to many-body Landa…
