Electronic cooling of a TiW alloy normal-metal island using Nb-based superconducting tunnel junctions
Joel Hätinen, Renan Pires Loreto, Arvind Kumar +2
TiW thin films remain non-superconducting down to millikelvin temperatures and are compatible with large-scale CMOS manufacturing, making them attractive for cryogenic and quantum…
Pathways and impediments towards a detection of the relic neutrino wind
Andrew J. Long, Michiru Uwabo-Niibo, Masahide Yamaguchi
A direct detection of the cosmic neutrino background (CNB) in laboratories on Earth has been called the ``holy grail'' of experimental neutrino physics, but a still more glorious p…
Plasma heating during the chiral plasma instability
Balin Armstrong, Andrew J. Long, Károly Seller +1
The presence of a chiral asymmetry in a relativistic plasma opens a tachyonic instability toward the growth of a helical magnetic field. We study the transfer of energy from the ch…
Nonthermal leptogenesis via cosmological gravitational particle production is tested by inflationary gravitational waves
Tammi Chowdhury, Leah Jenks, Edward W. Kolb +2
We explore the coincidence of scales between cosmic inflation and right-handed neutrinos in seesaw models. We show that inflation models, which will be tested by next-generation CM…
Extracting Axion String Network Parameters from Simulated CMB Birefringence Maps using Convolutional Neural Networks
Ray Hagimoto, Andrew J. Long, Mustafa A. Amin
Axion-like particles may form a network of cosmic strings in the Universe today that can rotate the plane of polarization of cosmic microwave background (CMB) photons. Future CMB o…
Resonant conversion of axion dark radiation into terahertz electromagnetic radiation in a neutron star magnetosphere
Andrew J. Long, Enrico D. Schiappacasse
In the strong magnetic field of a neutron star's magnetosphere, axions coupled to electromagnetism develop a nonzero probability to convert into photons. Past studies have revealed…
Thermal pressure on ultrarelativistic bubbles from a semiclassical formalism
Andrew J. Long, Jessica Turner
We study a planar bubble wall that is traveling at an ultrarelativistic speed through a thermal plasma. This situation may arise during a first-order electroweak phase transition i…
Cosmological gravitational particle production and its implications for cosmological relics
Edward W. Kolb, Andrew J. Long
Cosmological gravitational particle production (CGPP) is the creation of particles in an expanding universe due solely to their gravitational interaction. These particles can play…
Neutron star cooling with lepton-flavor-violating axions
Hong-Yi Zhang, Ray Hagimoto, Andrew J. Long
The cores of dense stars are a powerful laboratory for studying feebly coupled particles such as axions. Some of the strongest constraints on axionlike particles and their coupling…
