Microscopy of an ultranarrow Feshbach resonance using a laser-based atom collider: A quantum defect theory analysis
Matthew Chilcott, James F. E. Croft, Ryan Thomas +1
We employ a quantum defect theory framework to provide a detailed analysis of the interplay between a magnetic Feshbach resonance and a shape resonance in cold collisions of ultrac…
Scaling dynamics of the ultracold Bose gas
Ashton S. Bradley, Jordan Clarke, Tyler W. Neely +1
The large-scale expansion dynamics of quantum gases is a central tool for ultracold gas experiments and poses a significant challenge for theory. In this work we provide an exact r…
Localized big bang stability for the Einstein-scalar field equations
Florian Beyer, Todd A. Oliynyk
We prove the nonlinear stability in the contracting direction of Friedmann-Lemaître-Robertson-Walker (FLRW) solutions to the Einstein-scalar field equations in spacetime…
Spectral analysis for compressible quantum fluids
Ashton S. Bradley, R. Kishor Kumar, Sukla Pal +1
Turbulent fluid dynamics typically involves excitations on many different length scales. Classical incompressible fluids can be cleanly represented in Fourier space enabling spectr…
Standard Self-Confinement and Extrinsic Turbulence Models for Cosmic Ray Transport are Fundamentally Incompatible with Observations
Philip F. Hopkins, Jonathan Squire, Iryna S. Butsky +1
Models for cosmic ray (CR) dynamics fundamentally depend on the rate of CR scattering from magnetic fluctuations. In the ISM, for CRs with energies ~MeV-TeV, these fluctuations are…
Numerical Study of Cosmic Ray Confinement through Dust Resonant Drag Instabilities
Suoqing Ji, Jonathan Squire, Philip F. Hopkins
We investigate the possibility of cosmic ray (CR) confinement by charged dust grains through resonant drag instabilities (RDIs). We perform magnetohydrodynamic particle-in-cell sim…
