Photo-induced charge dynamics in 1-TaS
Francesco Petocchi, Jiyu Chen, Jiajun Li +2
Recent theoretical studies showed that the electronic structure of 1-TaS in the low-temperature commensurate charge density wave phase exhibits a nontrivial interplay betwee…
Photoinduced sliding transition into a hidden phase in van der Waals materials
Jiajun Li, Philipp Werner, Michael Sentef +1
We propose a generic scenario for metastability and excitation-induced switching in layered materials. Focusing on a minimal bilayer stack, where each layer consists of a honeycomb…
Dynamical mean-field study of a photon-mediated ferroelectric phase transition
Katharina Lenk, Jiajun Li, Philipp Werner +1
The interplay of light and matter gives rise to intriguing cooperative effects in quantum many-body systems. This is even true in thermal equilibrium, where the electromagnetic fie…
Collective theory for an interacting solid in a single-mode cavity
Katharina Lenk, Jiajun Li, Philipp Werner +1
We investigate the control of interacting matter through strong coupling to a single electromagnetic mode, such as the photon mode in a Fabry-Perot or split-ring cavity. For this p…
Pseudoparticle vertex solver for quantum impurity models
Aaram J. Kim, Jiajun Li, Martin Eckstein +1
We present a quantum impurity solver based on a pseudo-particle framework, which combines diagrammatic resummations for a three-point vertex with diagrammatic Monte Carlo sampling…
Twisted chiral superconductivity in photodoped frustrated Mott insulators
Jiajun Li, Markus Müller, Aaram J. Kim +2
Recent advances in ultrafast pump-probe spectroscopy provide access to hidden phases of correlated matter, including light-induced superconducting states, but the theoretical under…
