Observation of Superconducting Solitons by Terahertz-Light-Driven Persistent Pseudo-Spin Coherence
M. Mootz, C. Vaswani, C. Huang +8
Overcoming the decoherence bottleneck remains a central challenge for advancing coherent superconducting quantum device and information technologies. Solitons -- non-dispersive wav…
A sudden dramatic change and recovery of magneto-environment of a repeating fast radio burst
Y. Li, S. B. Zhang, Y. P. Yang +35
Fast radio bursts (FRBs) are millisecond-duration radio bursts with unidentified extra-galactic origin. Some FRBs exhibit mild magneto-ionic environmental variations, possibly attr…
A universal break in energy functions of three hyperactive repeating fast radio bursts
Q. Wu, F. Y. Wang, Z. Y. Zhao +16
Fast radio bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances with a mysterious origin. Observations show that at least some FRBs are produced by mag…
Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
Sudden polarization angle jumps of the repeating fast radio burst FRB 20201124A
J. R. Niu, W. Y. Wang, J. C. Jiang +41
We report the first detection of polarization angle (PA) orthogonal jumps, a phenomenon previously only observed from radio pulsars, from a fast radio burst (FRB) source FRB 202011…
Identifying axion conversion in compact star magnetospheres with radio-wave polarization signatures
Z. H. Xue, K. J. Lee, X. D. Gao +1
The axion is well motivated in physics. It solves the strong charge conjugation-parity reversal problem CP in fundamental physics and the dark matter problem in astronomy. Its inte…
Comparing recent PTA results on the nanohertz stochastic gravitational wave background
The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…
Practical approaches to analyzing PTA data: Cosmic strings with six pulsars
Hippolyte Quelquejay Leclere, Pierre Auclair, Stanislav Babak +69
We search for a stochastic gravitational wave background (SGWB) generated by a network of cosmic strings using six millisecond pulsars from Data Release 2 (DR2) of the European Pul…
Timing of Five PALFA-Discovered Millisecond Pulsars
