Investigating resonant low-energy electron attachment to formamide: Dynamics of model peptide bond dissociation and other fragmentation channels

Physical Review Research, 2021
We report experimental results on three-dimensional momentum-imaging measurements of anions generated via dissociative electron attachment to gaseous formamide. From the momentum images, we analyze the angular and kinetic-energy distributions for NH_{2}^{

Analytic description of atomic interaction at ultracold temperatures II: Scattering around a magnetic Feshbach resonance

, 2011
Starting from a multichannel quantum-defect theory, we derive analytic descriptions of a magnetic Feshbach resonance in an arbitrary partial wave $l$, and the atomic interactions around it.

Testing universality of Efimov physics across broad and narrow Feshbach resonances [PDF]

Nature Physics, 2016
The emergence of Efimov states in ultracold atomic systems is expected to have a universal behaviour, but a new experimental study defies this expectation, reporting a clear deviation around a narrow Feshbach resonance.

Feshbach resonance cooling of trapped atom pairs [PDF]

Physical Review A, 2005
Spectroscopic studies of few-body systems at ultracold temperatures provide valuable information that often cannot be extracted in a hot environment. Considering a pair of atoms, we propose a cooling mechanism that makes use of a scattering Feshbach resonance.

The Socialocene: From Capitalocene to Transnational Waste Regimes

Antipode, Volume 57, Issue 5, Page 1705-1724, September 2025.
Abstract In this article I will present a relational, and multiscalar, perspective on how state socialism interacted with and shaped the Capitalocene. I introduce a heuristic device, the term Socialocene, a transnational waste regime dominant through the Cold War‐era, that is, during what Will Steffen and colleagues call “the great acceleration”.

Microscopic calculations with noniterative finite amplitude methods and the application to neutron radiative captures and inelastic scatterings [PDF]

EPJ Web of Conferences
We derive the fully self-consistent quasiparticle random-phase approximation (QRPA) equations with noniterative finite amplitude methods and calculate the transition strengths of giant resonances. Then, we apply the QRPA results to both neutron radiative

Several Levels of Theory for Description of Isotope Effects in Ozone: Effect of Resonance Lifetimes and Channel Couplings [PDF]

, 2018
In this paper, two levels of theory are developed to determine the role of scattering resonances in the process of ozone formation. At the lower theory level, we compute resonance lifetimes in the simplest possible way, by neglecting all couplings ...

Feshbach resonances in ultracold ^{6,7}Li + ^{23}Na atomic mixtures

, 2008
We report a theoretical study of Feshbach resonances in $^{6}$Li + $^{23}$Na and $^{7}$Li + $^{23}$Na mixtures at ultracold temperatures using new accurate interaction potentials in a full quantum coupled-channel calculation. Feshbach resonances for $l=0$

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

Advanced Science, Volume 12, Issue 31, August 21, 2025.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

An analytic approach to probability tables for the unresolved resonance region

EPJ Web of Conferences, 2017
The Unresolved Resonance Region (URR) connects the fast neutron region with the Resolved Resonance Region (RRR). The URR is problematic since resonances are not resolvable experimentally yet the fluctuations in the neutron cross sections play a ...
