Detection of ultracold molecules using an optical cavity [PDF]
Physical Review A, 2018 We theoretically study nondestructive detection of ultracold molecules, using a Fabry-Perot cavity. Specifically, we consider vacuum Rabi splitting where we demonstrate the use of collective strong coupling for detection of molecules with many ...

Dynamical Phase Transitions in Open Quantum Walks
Advanced Quantum Technologies, Volume 8, Issue 11, November 2025.This work investigates dynamical phase transitions in discrete‐time quantum systems, highlighting the emergence of first‐ and second‐order transitions depending on whether detailed balance is preserved or broken. Using minimal quantum networks and quantum walks with internal degrees of freedom, the study reveals how spectral properties of the ...

Dynamics of ultracold polar molecules in a microwave field
New Journal of Physics, 2015 We analyze the temporal evolution of the population of ultracold polar molecules in a microwave (mw) field with a circular polarization. The molecules are in their ground $^{1}\Sigma $ state and treated as rigid rotors with a permanent dipole moment ...

Production and state-selective detection of ultracold, ground state RbCs molecules
, 2004 Using resonance-enhanced two-photon ionization, we detect ultracold, ground-state RbCs molecules formed via photoassociation in a laser-cooled mixture of 85Rb and 133Cs atoms.

Ultracold polar molecules near quantum degeneracy [PDF]
Faraday Discussions, 2009 We report the creation and characterization of a near quantum-degenerate gas of polar $^{40}$K-$^{87}$Rb molecules in their absolute rovibrational ground state. Starting from weakly bound heteronuclear KRb Feshbach molecules, we implement precise control of the molecular electronic, vibrational, and rotational degrees of freedom with phase-coherent ...

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model
Annalen der Physik, Volume 537, Issue 10, October 2025.Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Dynamic dipole polarizabilities of heteronuclear alkali dimers: optical response, trapping and control of ultracold molecules [PDF]
, 2017 In this article we address the general approach for calculating dynamical dipole polarizabilities of small quantum systems, based on a sum-over-states formula involving in principle the entire energy spectrum of the system. We complement this method by a

Strings of ultracold molecules in a synthetic dimension [PDF]
Physical Review A, 2018 We consider ultracold polar molecules trapped in a unit-filled one-dimensional chain in real space created with an optical lattice or a tweezer array and illuminated by microwaves that resonantly drive transitions within a chain of rotational states.

��berresonant Scattering of Ultracold Molecules
, 2012 Compared to purely atomic collisions, ultracold molecular collisions potentially support a much larger number of Fano-Feshbach resonances due to the enormous number of ro-vibrational states available. In fact, for alkali-metal dimers we find that the resulting density of resonances cannot be resolved at all, even on the sub-$ $K temperature scale of ...
