Quantum Simulation of Strongly Correlated Fermion-Phonon Models in Circuit QED
Tim Bode, Riccardo Roma, Stefan Schmitz +4
Gate-based digital quantum simulations offer an exciting new paradigm for studying the many-body physics of strongly correlated systems. In this context, electron-phonon models are…

Digital-Analog Simulations of Schrödinger Cat States in the Dicke-Ising Model
Dmitriy S. Shapiro, Yannik Weber, Tim Bode +2
The Dicke-Ising model, one of the few paradigmatic models of matter-light interaction, exhibits a superradiant quantum phase transition above a critical coupling strength. However,…

Berezinskii-Kosterlitz-Thouless transitions in a topological superconductor-ferromagnet-superconductor junction
Adrian Reich, Dmitriy S. Shapiro, Alexander Shnirman
We investigate quantum phase transitions in a topological Josephson junction with an embedded ferromagnetic layer, revealing a rich landscape of critical phenomena. The low-energy…
