Interplay of Zeeman field, Rashba spin-orbit interaction, and superconductivity: Transition temperature and quasiparticle excitation

Posted by dbos October 8, 2024October 21, 2024UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Chen Pang, Yi Zhou, , , | Summary: This paper provides a theoretical analysis on the effects of an external Zeeman field and Rashba spin-orbit interactions on superconductivity. We have extensively studied their influence on the superconducting transition temperature $T_c$ and the quasiparticle excitation energy. Our investigation […]

Highly Excited Electron Cyclotron for QCD Axion and Dark-Photon Detection

Posted by dbos October 7, 2024October 21, 2024Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Xing Fan, Gerald Gabrielse, Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong | Summary: We propose using highly excited cyclotron states of a trapped electron to detect meV axion and dark photon dark matter, marking a significant improvement over our previous proposal and demonstration [Phys. […]

Mind the kinematics simulation of planet-disk interactions: time evolution and numerical resolution

Posted by October 7, 2024Peking

Kavli Affiliate: Ruobing Dong | First 5 Authors: Kan Chen, Ruobing Dong, , , | Summary: Planet-disk interactions can produce kinematic signatures in protoplanetary disks. While recent observations have detected non-Keplerian gas motions in disks, their origins are still being debated. To explore this, we conduct 3D hydrodynamic simulations using the code FARGO3D to study […]

Early auditory and adult mating experiences interact with singer identity to shape neural responses to song in female zebra finches

Posted by dbos October 7, 2024October 21, 2024Columbia

Kavli Affiliate: Sarah Woolley | Authors: Isabella Catalano and Sarah C Woolley | Summary: Social and sensory experiences across the lifespan can shape social interactions, however, experience-dependent plasticity is widely studied within discrete life stages. In the socially monogamous zebra finch, in which females use learned vocal signals to identify individuals and form long-lasting pair […]

A long spin period for a sub-Neptune-mass exoplanet

Posted by dbos October 7, 2024October 21, 2024MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ellen M. Price, Juliette Becker, Zoë L. de Beurs, Leslie A. Rogers, Andrew Vanderburg | Summary: HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital period and deep transit make it an ideal candidate for detecting oblateness photometrically. We present a […]

Age-dating early quiescent galaxies: high star-formation efficiency, but consistent with direct, higher-redshift observations

Posted by dbos October 7, 2024October 21, 2024Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Crispin Turner, Sandro Tacchella, Francesco D’Eugenio, Stefano Carniani, Mirko Curti | Summary: We present a detailed analysis of JWST/NIRSpec and NIRCam observations of ZF-UDS-7329, a massive, quiescent galaxy at redshift $z=3.2$, which has been put forward to challenge cosmology and galaxy formation physics. Our study extends previous […]

Tomographic constraint on anisotropic cosmic birefringence

Posted by dbos October 7, 2024October 21, 2024Tokyo

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, , , , | Summary: We for the first time constrain anisotropic cosmic birefringence generated at reionization using Planck PR4 polarization data. Several recent analyses of WMAP and Planck polarization data have found a tantalizing hint of isotropic cosmic birefringence. Ongoing and future CMB experiments […]

Classification of radio backgrounds at cosmic dawn and 21-cm signal confirmation using neural networks

Posted by dbos October 7, 2024Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Anastasia Fialkov, Rennan Barkana, , | Summary: Several ongoing and upcoming radio telescopes aim to detect either the global 21-cm signal or the 21-cm power spectrum. The extragalactic radio background, as detected by ARCADE-2 and LWA-1, suggests a strong radio background from cosmic dawn, which […]

Direction Modulation Design for UAV Assisted by IRS with discrete phase shift

Posted by October 7, 2024Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Maolin Li, Wei Gao, Qi Wu, Feng Shu, Cunhua Pan | Summary: As a physical layer security technology, directional modulation (DM) can be combined with intelligent reflect-ing surface (IRS) to improve the security of drone communications. In this paper, a directional modulation scheme assisted by the IRS […]

3D printed mesoporous superconductors with periodic order on three length scales and enhanced properties via block copolymer directed self-assembly

Posted by dbos October 6, 2024Cornell

Kavli Affiliate: Ulrich B. Wiesner | First 5 Authors: Fei Yu, R. Paxton Thedford, Thomas A. Tartaglia, Sejal S. Sheth, Guillaume Freychet | Summary: Solution-based soft matter self-assembly (SA) promises unique materials properties from approaches including additive manufacturing/three-dimensional (3D) printing. We report direct ink writing derived, hierarchically porous transition metal nitride superconductors (SCs) and precursor […]
