Low-temperature chemistry using the R-matrix method [PDF]
, 2016 Techniques for producing cold and ultracold molecules are enabling the study of chemical reactions and scattering at the quantum scattering limit, with only a few partial waves contributing to the incident channel, leading to the observation and even ...

Observation of Linear and Nonlinear Light Trapping on Topological Dislocations
Laser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Vibrational energy transfer in ultracold molecule - molecule collisions
, 2008 We present a rigorous study of vibrational relaxation in p-H2 + p-H2 collisions at cold and ultracold temperatures and identify an efficient mechanism of ro-vibrational energy transfer.

Journal of Gastroenterology and Hepatology, Volume 41, Issue 4, Page 1311-1322, April 2026.To improve triage for liver fibrosis in MASLD primary care and where elastography is unavailable, a novel algorithm, FAP Index, that requires one fibrogenesis‐relevant, rapid enzyme assay, was devised and validated. FAP Index increased advanced fibrosis risk stratification accuracy by greatly reducing the frequency of indeterminate results compared to ...

Finite-range effects in dilute Fermi gases at unitarity
, 2011 We develop a theoretical method going beyond the contact-interaction approximation frequently used in mean-field theories of many-fermion systems, based on the low-energy T-matrix of the pair potential to rigorously define the effective radius of the ...

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States
Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...
