Vertex-based Diagrammatic Treatment of Light-Matter-Coupled Systems
Aaram J. Kim, Katharina Lenk, Jiajun Li +2
We propose a diagrammatic Monte Carlo approach for general spin-boson models, which can be regarded as a generalization of the strong-coupling expansion for fermionic impurity mode…
Memory truncated Kadanoff-Baym equations
Christopher Stahl, Nagamalleswararao Dasari, Jiajun Li +3
The Keldysh formalism for nonequilibrium Green's functions is a powerful theoretical framework for the description of the electronic structure, spectroscopy, and dynamics of strong…
Effective theory of lattice electrons strongly coupled to quantum electromagnetic fields
Jiajun Li, Lukas Schamriß, Martin Eckstein
Recent experiments have revealed the tantalizing possibility of fabricating lattice electronic systems strongly coupled to quantum fluctuations of electromagnetic fields, e.g., by…
A quantum Boltzmann equation for strongly correlated electrons
Antonio Picano, Jiajun Li, Martin Eckstein
Collective orders and photo-induced phase transitions in quantum matter can evolve on timescales which are orders of magnitude slower than the femtosecond processes related to elec…
