High-frequency approximation for periodically driven quantum systems from a Floquet-space perspective

New Journal of Physics, 2015
We derive a systematic high-frequency expansion for the effective Hamiltonian and the micromotion operator of periodically driven quantum systems. Our approach is based on the block diagonalization of the quasienergy operator in the extended Floquet ...

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{

Classical Casimir force from a quasi-condensate of light

Physical Review Research, 2020
We show that weakly incoherent optical beams propagating in a Kerr medium exhibit a universal algebraic coherence after a short propagation time, mimicking the quasi-long-range order of ultracold quantum Bose gases in two dimensions.

From Nano Robotic Manipulation to Nano Manipulation Robot

SmartBot, Volume 1, Issue 3, September 2025.
This review addresses a critical research gap by summarizing advancements in nano robotic manipulation, tracing its evolution from passive observation to autonomous nanomanipulation robots. It explores the interplay of observation, construction, and operation, unveiling fundamental principles of atomic‐scale control. The review establishes a systematic

Functional renormalization and ultracold quantum gases

, 2009
The method of functional renormalization is applied to the theoretical investigation of ultracold quantum gases. Flow equations are derived for a Bose gas with approximately pointlike interaction, for a Fermi gas with two (hyperfine) spin components in the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensation (BEC) crossover and for a Fermi gas

Neural-network quantum states for ultra-cold Fermi gases

Communications Physics
Ultra-cold Fermi gases exhibit a rich array of quantum mechanical properties, including the transition from a fermionic superfluid Bardeen-Cooper-Schrieffer (BCS) state to a bosonic superfluid Bose-Einstein condensate (BEC). While these properties can be

Collision‐Induced Fragmentation of Oligosaccharides: Mechanistic Insights for Mass Spectrometry‐Based Glycomics

Angewandte Chemie International Edition, Volume 64, Issue 33, August 11, 2025.
Glycan fragmentation with collision‐induced dissociation (CID) mass spectrometry (MS) leads to a range of specific disassembly mechanisms, which are being reviewed in detail. Abstract Structural alterations in oligosaccharides are often associated with disease, positioning clinical glycomics as an emerging tool for diagnostics.

Resonant control of spin dynamics in ultracold quantum gases by microwave dressing [PDF]

, 2006
We study experimentally interaction-driven spin oscillations in optical lattices in the presence of an off-resonant microwave field. We show that the energy shift induced by this microwave field can be used to control the spin oscillations by tuning the ...

Algebraic Bethe ansatz method for the exact calculation of energy spectra and form factors: applications to models of Bose-Einstein condensates and metallic nanograins

, 2003
In this review we demonstrate how the algebraic Bethe ansatz is used for the calculation of the energy spectra and form factors (operator matrix elements in the basis of Hamiltonian eigenstates) in exactly solvable quantum systems.
