Dispersion of First Sound in a Weakly Interacting Ultracold Fermi Liquid

Annalen der Physik, Volume 537, Issue 11, November 2025.
 The weak‐interaction, low‐temperature region of the phase diagram of a Fermi gas the so‐called Fermi liquid regime, which has been somewhat overlooked in ultracold gases‐is investigated. Precise and measurable predictions are presented for the viscosity and dispersion of first sound to leading order in the scattering length.

Coherent control of ultracold 85Rb trap-loss collisions with nonlinearly frequency-chirped light

, 2011
We present results on coherent control of ultracold trap-loss collisions using 40 ns pulses of nonlinearly frequency-chirped light. The chirps, either positive or negative, sweep ~1 GHz in 100 ns and are centered at various detunings below the D2 line of

Coherence, Transport, and Chaos in 1D Bose–Hubbard Model: Disorder vs. Stark Potential

Fortschritte der Physik, Volume 73, Issue 11, November 2025.
Quantum coherence and criticality in finite Bose–Hubbard chains are investigated using exact diagonalization. Thermal fluctuations, Stark potential, and disorder reshape coherence, visibility, and superfluid response. Finite‐size systems show signatures of quantum criticality, with disorder suppressing global superfluidity but preserving local ...

Density functional theory for strongly-correlated bosonic and fermionic ultracold dipolar and ionic gases

, 2015
We introduce a density functional formalism to study the ground-state properties of strongly-correlated dipolar and ionic ultracold bosonic and fermionic gases, based on the self-consistent combination of the weak and the strong coupling limits. Contrary

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.

Ultracold spin-polarized mixtures of 2Sigma molecules with S-state atoms: Collisional stability and implications for sympathetic cooling

, 2011
The prospects of sympathetic cooling of polar molecules with magnetically co-trapped alkali-metal atoms are generally considered poor due to strongly anisotropic atom-molecule interactions leading to large spin relaxation rates.

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction

Contributions to Plasma Physics, Volume 65, Issue 8-9, October 2025.
ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{
