Optical Trap** of a Polyatomic Molecule in an -Type Parity Doublet State

C Hallas, NB Vilas, L Anderegg, P Robichaud… - Physical Review Letters, 2023 - APS
We report optical trap** of a polyatomic molecule, calcium monohydroxide (CaOH). CaOH
molecules from a magneto-optical trap are sub-Doppler laser cooled to 20 (3) μ K in free …

Bypassing thermalization timescales in temperature estimation using prethermal probes

N Anto-Sztrikacs, HJD Miller, A Nazir, D Segal - Physical Review A, 2024 - APS
We introduce prethermal temperature probes for sensitive, fast, and robust temperature
estimation. While equilibrium thermal probes with a manifold of quasidegenerate excited …

Population Oscillations and Ubiquitous Coherences in multilevel quantum systems driven by incoherent radiation

A Dodin, TV Tscherbul, P Brumer - The Journal of Physical …, 2024 - ACS Publications
We consider incoherent excitation of multilevel quantum systems, eg, molecules with
multiple vibronic states. We show that (1) the geometric constraints of the matter–field …

Prospects for measuring the electron's electric dipole moment with polyatomic molecules in an optical lattice

R Bause, N Balasubramanian, T Fikkers… - arxiv preprint arxiv …, 2024 - arxiv.org
We present the conceptual design of an experiment to measure the electron's electric dipole
moment (eEDM) using $^{138} $ BaOH molecules in an optical lattice. The BaOH molecule …

Spectroscopy of laser cooling transitions in MgF

NH Pilgram, B Baldwin, DS La Mantia, SP Eckel… - arxiv preprint arxiv …, 2024 - arxiv.org

Open Quantum System Techniques Beyond the Lindblad Equation

N Anto-Sztrikacs - 2024 - search.proquest.com
Quantum systems are inherently open to their environment and thus they evolve under the
influence of dissipation, decoherence and driving from external fields. This poses a …
