Charge Exchange Dynamics in Cold Collisions of $^{40}$CaH$^+$ and $^{39}$K

Preprint · February 9, 2026 We report the observation of charge-exchange collisions between trapped calcium monohydride molecular ions ($^{40}$CaH$^+$) and ultracold potassium atoms ($^{39}$K) in a hybrid ion-atom trap. The measured charge-exchange rate coefficient is significantly s ... Link to item Cite

Non-Gaussian Phase Transition and Cascade of Instabilities in the Dissipative Quantum Rabi Model

Preprint · July 9, 2025 The open quantum Rabi model describes a two-level system coupled to a harmonic oscillator. A Gaussian phase transition for the nonequilibrium steady states has been predicted when the bosonic mode is soft and subject to damping. We show that oscillator dep ... Link to item Cite
