Anomalous Expansion of Attractively Interacting Fermionic Atoms in an Optical Lattice [PDF]

, 2009
Strong correlations can dramatically modify the thermodynamics of a quantum many-particle system. Especially intriguing behaviour can appear when the system adiabatically enters a strongly correlated regime, for the interplay between entropy and strong ...

Quasilinear theory of collisionless Fermi acceleration in a multicusp magnetic confinement geometry

, 1999
Particle motion in a cylindrical multiple-cusp magnetic field configuration is shown to be highly (though not completely) chaotic, as expected by analogy with the Sinai billiard.

Cosmic ray feedback in the FIRE simulations: constraining cosmic ray propagation with GeV gamma ray emission [PDF]

, 2019
We present the implementation and the first results of cosmic ray (CR) feedback in the Feedback In Realistic Environments (FIRE) simulations. We investigate CR feedback in non-cosmological simulations of dwarf, sub-$L\star$ starburst, and $L\star ...

VUV irradiance measurement of a 2.45 GHz microwave-driven hydrogen discharge

, 2015
Absolute values of VUV-emission of a 2.45 GHz microwave-driven hydrogen discharge are reported. The measurements were performed with a robust and straightforward method based on a photodiode and optical filters.

But What About... Cosmic Rays, Magnetic Fields, Conduction, & Viscosity in Galaxy Formation [PDF]

, 2020
We present a suite of high-resolution cosmological simulations, using the FIRE-2 feedback physics together with explicit treatment of magnetic fields, anisotropic conduction and viscosity, and cosmic rays (CRs) injected by supernovae (including ...

Non inductive formation of an extremely overdense spherical Tokamak by electron Bernstein wave heating and current drive on LATE

EPJ Web of Conferences, 2015
An extremely overdense special Tokamak plasma has been non-inductively formed and maintained by electron Bernstein (EB) wave heating and current drive in the Low Aspect ratio Torus Experiment (LATE) device.

Radioactive Ion Sources

, 2014
This chapter provides an overview of the basic requirements for ion sources designed and operated in radioactive ion beam facilities. The facilities where these sources are operated exploit the isotope separation online (ISOL) technique, in which a ...

Numerical simulations of gas mixing effect in electron cyclotron resonance ion sources

Physical Review Accelerators and Beams, 2017
The particle-in-cell Monte Carlo collisions code nam-ecris is used to simulate the electron cyclotron resonance ion source (ECRIS) plasma sustained in a mixture of Kr with O_{2}, N_{2}, Ar, Ne, and He.
