Feshbach-Stabilized Insulator of Bosons in Optical Lattices
, 2015 Feshbach resonances - namely resonances between an unbound two-body state (atomic state) and a bound (molecular) state, differing in magnetic moment - are a unique tool to tune the interaction properties of ultracold atoms.

Bosonic Szilard engine assisted by Feshbach resonances [PDF]
Physical Review A, 2018 It was recently found that the information-to-work conversion in a quantum Szilard engine can be increased by using a working medium of bosons with attractive interactions. In the original scheme, the work output depends on the insertion and removal position of an impenetrable barrier that acts like a piston, separating the chambers of the engine. Here,

Localized and Extended Phases in Square Moiré Patterns
Annalen der Physik, Volume 537, Issue 6, June 2025.Rotated superimposed lattices in two dimensions, the termed moiré patterns, represent a clear example of how the structure affects the physical properties of a particle moving on it. A robust numerical treatment of continuous and discrete models leads to confirm that while localized states result from angles that produce non‐commensurable lattices ...

Semiclassical Resonances via Meromorphy of the Resolvent and the S-Matrix
International Journal of Analysis and Applications, 2020 The purpose of this paper is to describe the basic problems of resonances via meromorphic continuation of the resolvent and the scattering matrix. An example from mathematical physics is given by investigating the poles of the resolvent of semiclassical ...

Prospects of Forming High-Spin Polar Molecules from Ultracold Atoms
Physical Review X, 2020 We investigate Feshbach resonances in collisions of high-spin atoms such as Er and Dy with closed-shell atoms such as Sr and Yb, using coupled-channel scattering and bound-state calculations. We consider both low-anisotropy and high-anisotropy limits. In

Feshbach spectroscopy of Cs atom pairs in optical tweezers
New Journal of Physics, 2022 We prepare pairs of ^133 Cs atoms in a single optical tweezer and perform Feshbach spectroscopy for collisions of atoms in the states ( f = 3, m _f = ±3).

Exotic Hadrons as Feshbach Resonances
Acta Physica Polonica B Proceedings Supplement, 2014 Since ten years ago a host of exotic resonances have challenged the usual quarkonium picture. A number of ideas have been put forward to explain these new states, but a comprehensive framework is still missing. We review the estimates for prompt production cross sections at hadron collider, and show that the interpretation of exotic states in terms of ...

Feshbach Resonance Management for Bose-Einstein Condensates
Physical Review Letters, 2003 An experimentally realizable scheme of periodic sign-changing modulation of the scattering length is proposed for Bose-Einstein condensates similar to dispersion-management schemes in fiber optics. Because of controlling the scattering length via the Feshbach resonance, the scheme is named Feshbach-resonance management.

Journal of Contingencies and Crisis Management, Volume 33, Issue 1, March 2025.ABSTRACT This study examines how empathy, operationalized into affective and cognitive dimensions, influences stakeholders' perceptions during organisational crises. Also, the study explores the mediating role of account acceptance in the relationship between crisis response strategies and organisational outcomes.

The sources of national pride: Evidence from China and the United States
Nations and Nationalism, Volume 30, Issue 4, Page 547-564, October 2024.Abstract National pride relates to nationalism, one of the most powerful forces in modern politics. Many surveys have shown that most citizens are proud of their countries, but few have directly examined the underlying reasons for why people are proud of their countries. Using parallel national surveys in China and the United States, we investigate the
