Lieb's Theorem and Maximum Entropy Condensates

Autor: Joseph Tindall, Frank Schlawin, Michael Sentef, Dieter Jaksch

Publikováno v: Quantum, Vol 5, p 610 (2021)

Coherent driving has established itself as a powerful tool for guiding a many-body quantum system into a desirable, coherent non-equilibrium state. A thermodynamically large system will, however, almost always saturate to a featureless infinite tempe

Examining Electron-Boson Coupling Using Time-Resolved Spectroscopy

Autor: Michael Sentef, Alexander F. Kemper, Brian Moritz, James K. Freericks, Zhi-Xun Shen, Thomas P. Devereaux

Publikováno v: Physical Review X, Vol 3, Iss 4, p 041033 (2013)

Nonequilibrium pump-probe time-domain spectroscopies can become an important tool to disentangle degrees of freedom whose coupling leads to broad structures in the frequency domain. Here, using the time-resolved solution of a model photoexcited elect

Neural-network quantum states (NQS) have been shown to be a suitable variational ansatz to simulate out-of-equilibrium dynamics in two-dimensional systems using time-dependent variational Monte Carlo (t-VMC). In particular, stable and accurate time p

Cavity quantum materials

Autor: Michael Sentef, Frank Schlawin, Dante Kennes

Publikováno v: Applied Physics Reviews

The emergent field of cavity quantum materials bridges collective many-body phenomena in solid-state platforms with strong light-matter coupling in cavity quantum electrodynamics (cavity QED). This brief review provides an overview of the state of th

Quantum nonlinear phononics route towards nonequilibrium materials engineering: Melting dynamics of a ferrielectric charge density wave

Autor: Mario Puviani, Michael Sentef, Matteo Puviani

Publikováno v: Physical Review B

Negative nonlinear electron-phonon coupling involving an infrared-active phonon mode can lead to an instability towards the formation of a polar lattice distortion with ferrielectric (FE) moments accompanied by an electronic charge-density wave (CDW)
