Observational Signatures of Traversable Wormholes

Kavli Affiliate: Cheng Peng | First 5 Authors: Yiqian Chen, Lang Cheng, Peng Wang, Haitang Yang, | Summary: In this paper, we study the observational signatures of traversable Simpson-Visser wormholes illuminated by luminous celestial spheres and orbiting hot spots. We demonstrate that when light sources and observers are on the same side of the wormholes, […]

Experimental tests of the full spin torque conductivity tensor in epitaxial IrO2 thin films

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Michael Patton, Daniel A. Pharis, Gautam Gurung, Xiaoxi Huang, Gahee Noh | Summary: Unconventional spin-orbit torques arising from electric-field-generated spin currents in anisotropic materials have promising potential for spintronic applications, including for perpendicular magnetic switching in high-density memory applications. Here we determine all the independent elements […]

Evolving Dark Energy or Supernovae Systematics?

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: Recent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with DESI measurements of baryon acoustic […]

Spontaneous calcium transients in hair cell stereocilia

Kavli Affiliate: Dwight Bergles | Authors: Saman Hussain, Miloslav Sedlacek, Runjia Cui, Wendy Zhang-Hooks, Dwight E Bergles, Jung-Bum Shin, Katie Kindt and Bechara Kachar | Summary: The hair bundle of auditory and vestibular hair cells converts mechanical stimuli into electrical signals through mechanoelectrical transduction (MET). The MET apparatus is built around a tip link that […]

Quantifying Bursty Star Formation in Dwarf Galaxies

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yuan-Sen Ting, Alexander P. Ji, , , | Summary: Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than $sim$100 Myr should lead to discontinuous tracks in […]

Entanglement dynamics in 2d HCFTs on the curved background: the case of q-Möbius Hamiltonian

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Chen Bai, Akihiro Miyata, Masahiro Nozaki, , | Summary: We will explore the dynamical property of non-equilibrium phenomena induced by two-dimensional holographic conformal field theory (2d holographic CFT) Hamiltonian on the curved spacetime by studying the time dependence of the entanglement entropy and mutual information. Here, holographic […]

Dynamic medial parietal and hippocampal deactivations under DMT relate to sympathetic output and altered sense of time, space, and the self

Kavli Affiliate: Adam Gazzaley | Authors: Lorenzo Pasquini, Alexander Simon, Courtney Gallen, Hannes Kettner, Leor Roseman, Adam Gazzaley, Robin Carhart-Harris and Christopher Timmermann | Summary: N,N-Dimethyltryptamine (DMT) is a serotonergic psychedelic, known to rapidly induce short-lasting alterations in conscious experience, characterized by a profound and immersive sense of physical transcendence alongside rich and vivid auditory […]
