Formation of ultracold triatomic molecules by electric microwave association

Physical Review Research
A theoretical model is proposed for the formation of ultracold ground-state triatomic molecules in weakly bound energy levels. The process is driven by the electric component of a microwave field, which induces the association of an ultracold atom ...

Ultracold molecular spectroscopy: toward the narrow-line cooling of molecules

New Journal of Physics, 2015
A new spectroscopic method that utilizes microwave transition of ultracold molecules is demonstrated. The narrow spectral linewidth (approximately 100 Hz) was guaranteed by preparing molecules at low temperature, and a high signal-to-noise ratio was ...

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

Advanced Optical Materials, Volume 13, Issue 31, November 5, 2025.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Characteristics of a magneto-optical trap of molecules

New Journal of Physics, 2017
We present the properties of a magneto-optical trap (MOT) of CaF molecules. We study the process of loading the MOT from a decelerated buffer-gas-cooled beam, and how best to slow this molecular beam in order to capture the most molecules.

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 ...

Theory of long-range ultracold atom-molecule photoassociation

, 2015
The creation of ultracold molecules is currently limited to diatomic species. In this letter we present a theoretical description of the photoassociation of ultracold atoms and molecules to create ultracold excited triatomic molecules, thus being a novel

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.
