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{

Photonic Floquet–Bloch Oscillations Dominated by Floquet Gauge

Laser &Photonics Reviews, Volume 19, Issue 17, September 4, 2025.
A new type of Bloch oscillations (namely, asymmetric Floquet–Bloch oscillations) whose evolution is biased along the evolution dimension is proposed and visually observed. The Floquet gauge can determine the light broadening to be biased toward the first or second half of the period. These findings reveal a new mechanism for wave packet revival and may

Laser cooling of a fermionic molecule

Physical Review Research
Only bosonic molecular species have been directly laser cooled to date, primarily due to an abundance of bosonic isotopes in nature and to their simpler hyperfine structure.

CONDENSATION OF COLD NEUTRONS – IDEA OF G.A.GAMOW. CHEMICAL PROPERTIES OF THE NEUTRON MATTER AND ITS PLACE IN THE PERIODIC SYSTEM OF ELEMENTS

Odessa Astronomical Publications, 2018
Today, the neutron matter and neutron stars are already substantially rooted in the nuclear physics and astrophysics, and it is logical to have their consideration of them in terms of chemical properties and principles of general chemistry. The formation

Inelastic Collisions in an Ultracold quasi-2D Gas

, 2009
We present a formalism for rigorous calculations of cross sections for inelastic and reactive collisions of ultracold atoms and molecules confined by laser fields in quasi-2D geometry.

Automated graph-based detection of quantum control schemes: Application to molecular laser cooling

Physical Review Research
One of the demanding frontiers in ultracold quantum science is identifying laser cooling schemes for complex atoms and molecules out of their vast spectra of internal states. Motivated by the prospect of expanding the set of available ultracold molecules

Sweeping molecules with light

New Journal of Physics, 2017
Many areas of physics—precision measurements, quantum information, and physical chemistry, to name a few—are starting to benefit from the enormous advantages offered by cold and ultracold polar molecules.

Ultracold polar molecules as qudits

New Journal of Physics, 2020
We discuss how the internal structure of ultracold molecules, trapped in the motional ground state of optical tweezers, can be used to implement qudits. We explore the rotational, fine and hyperfine structure of ^40 Ca ^19 F and ^87 Rb ^133 Cs, which are

Inelastic collisions of ultracold triplet Rb$_\textbf{2}$ molecules in the rovibrational ground state

, 2016
Exploring inelastic and reactive collisions on the quantum level is a main goal of the developing field of ultracold chemistry. We present first experimental studies of inelastic collisions of metastable ultracold triplet molecules in the vibrational ...
