Dipolar collisions of polar molecules in the quantum regime

open access: yes, 2010
Ultracold polar molecules offer the possibility of exploring quantum gases with interparticle interactions that are strong, long-range, and spatially anisotropic.

Formation of ultracold dipolar molecules in the lowest vibrational levels by photoassociation [PDF]

open access: yes, 2008
We recently reported the formation of ultracold LiCs molecules in the rovibrational ground state X1Sigma+,v''=0,J''=0 [J. Deiglmayr et al., PRL 101, 133004 (2008)].

Laser cooling of a diatomic molecule

open access: yes, 2011
It has been roughly three decades since laser cooling techniques produced ultracold atoms, leading to rapid advances in a vast array of fields. Unfortunately laser cooling has not yet been extended to molecules because of their complex internal structure.

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Electric field-dependent dynamic polarizability and "magic" conditions for optical trapping of polar molecules

open access: yes, 2010
Selection of "magic" trapping conditions with ultracold atoms or molecules, where pairs of internal states experience identical trapping potentials, brings substantial benefits to precision measurements and quantum computing schemes.

Ultracold nonreactive molecules in an optical lattice: connecting chemistry to many-body physics [PDF]

open access: yes, 2015
We derive effective lattice models for ultracold bosonic or fermionic nonreactive molecules (NRMs) in an optical lattice, analogous to the Hubbard model that describes ultracold atoms in a lattice.

Universal relations for ultracold reactive molecules [PDF]

open access: yesScience Advances, 2020
There exist universal relations between the two-body loss in chemical reactions of ultracold molecules and many-body correlations.

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

open access: yesExperimental Physiology, EarlyView.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...

Density Modulations of Zero Sound

open access: yesAnnalen der Physik, Volume 538, Issue 2, February 2026.
Zero sound is a collective mode of the strongly interacting quantum gas that propagates when atomic collisions are negligible, similarly to a plasmon. This work aims at investigating the conditions under which a density modulation associated to this collective mode travels coherently through a strongly interacting Fermi gas.

Observation of Feshbach-like resonances in collisions between ultracold molecules

open access: yes, 2004
We observe magnetically tuned collision resonances for ultracold Cs2 molecules stored in a CO2-laser trap. By magnetically levitating the molecules against gravity, we precisely measure their magnetic moment.
