Finite-temperature Green's function cluster expansion from thermofield doubles: Breakdown of the polaron picture
M. R. Carbone, S. Fomichev, B. Kloss +4
We introduce a method, numerically exact in principle, for computing the momentum- and frequency-resolved single-particle Green's function of a polaron at finite temperature. The m…
Phonon state tomography of electron correlation dynamics in optically excited solids
Mattia Moroder, Matteo Mitrano, Ulrich Schollwöck +2
We introduce phonon state tomography (PST) as a diagnostic probe of electron dynamics in solids whose phonons are optically excited by a laser pulse at initial time. Using a projec…
Ultrafast dynamics of a fermion chain in a terahertz field-driven optical cavity
Mohsen Yarmohammadi, John Sous, Marin Bukov +1
We study the effect of a terahertz field-driven single cavity mode for ultrafast control of a fermion chain with dissipation-induced nonlinearity and quadratic coupling to an infra…
Unidirectional subsystem symmetry in a hole-doped honeycomb-lattice Ising magnet
Sambuddha Sanyal, Alexander Wietek, John Sous
We study a model of a hole-doped collinear Ising antiferromagnet on the honeycomb lattice as a route toward the realization of subsystem symmetry. We find nearly exact conservation…
Strongly correlated ladders in K-doped -terphenyl crystals
John Sous, Natalia A. Gadjieva, Colin Nuckolls +2
Potassium-doped terphenyl has recently attracted attention as a potential host for high-transition-temperature superconductivity. Here, we elucidate the many-body electronic struct…
Bond-Peierls polaron: Moderate mass enhancement and current-carrying ground state
Matthew R. Carbone, Andrew J. Millis, David R. Reichman +1
We study polarons in the one-dimensional Bond-Peierls electron-phonon model, in which phonons on bonds of a lattice modulate the hopping of electrons between lattice sites, and con…
