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

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

Kavli Affiliate: Peter Graham | 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. Rev. Lett. 129, 261801]. When the axion mass matches the cyclotron frequency $ω_c$, the cyclotron state is resonantly excited, […]

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

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 […]

Classification of Radio Backgrounds at Cosmic Dawn and 21 cm Signal Confirmation Using Neural Networks

Kavli Affiliate: George Efstathiou | 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 can significantly alter the cosmological 21 cm signal, enhancing both […]

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

Kavli Affiliate: Ulrich Wiesner | 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 oxides, structure-directed by Pluronics-family block copolymer (BCP) SA and heat treated in various environments. SCs with periodic lattices on […]
