Decoherence from general relativity

IJ Allali, MP Hertzberg - Physical Review D, 2021 - APS
It is of great interest to explore matter in nontrivial quantum arrangements, including
Schrödinger catlike states. Such states are sensitive to decoherence from their environment …

Near-field diffraction of protons by a nanostructured metallic grating under external electric field: asymmetry and sidebands in Talbot self-imaging

S Barman, S Bhattacharjee - New Journal of Physics, 2023 - iopscience.iop.org
Self-imaging in near-field diffraction is a practical application of coherent manipulation of
matter waves in Talbot interferometry. In this work, near-field diffraction of protons by a …

Atom chip apparatus for experiments with ultracold rubidium and potassium gases

MK Ivory, AR Ziltz, CT Fancher, AJ Pyle… - Review of Scientific …, 2014 - pubs.aip.org
We present a dual chamber atom chip apparatus for generating ultracold 87 Rb and 39 K
atomic gases. The apparatus produces quasi-pure Bose-Einstein condensates of 10 4 87 …

Longitudinal dynamics with rf phase modulation in the Brazilian electron storage ring

NP Abreu, RHA Farias, PF Tavares - Physical Review Special Topics …, 2006 - APS
In the Brazilian synchrotron light source (LNLS—Laboratório Nacional de Luz Síncrotron),
we observed that modulating the phase of the accelerating fields at approximately twice the …

Topological analysis of chaotic transport through a ballistic atom pump

TA Byrd, JB Delos - Physical Review E, 2014 - APS
We examine a system consisting of two reservoirs of particles connected by a channel. In the
channel are two oscillating repulsive potential-energy barriers. It is known that such a …

Quantum reflection from an oscillating surface

B Herwerth, M DeKieviet, J Madronero… - Journal of Physics B …, 2013 - iopscience.iop.org
We describe an experimentally realistic situation of the quantum reflection of helium atoms
from an oscillating surface. The temporal modulation of the potential induces clear …

Simulations of beam-beam and beam-wire interactions in RHIC

HJ Kim, T Sen, NP Abreu, W Fischer - Physical Review Special Topics …, 2009 - APS
The beam-beam interaction is one of the dominant sources of emittance growth and
luminosity lifetime deterioration. A current-carrying wire has been proposed to compensate …

Classification and time evolution of density matrices for a N-state system

IP Mendaš - Journal of mathematical physics, 2008 - pubs.aip.org
A possible method of classifying all density matrices for a N-state quantum system into
different types, using the sameness of the characteristic polynomial of density matrices …

Axions in a Dark Universe: Dark Matter Behavior and Novel Dynamics Inform Cosmological Observations

IJ Allali - 2023 - search.proquest.com
Despite its crucial role in cosmology, little is known about the precise nature of dark matter.
This work investigates the nature of dark matter, primarily the QCD axion and other axion …
