Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Yunyue Chen, Yuanqi Du, Max Tegmark, | Summary: Integrating physical inductive biases into machine learning can improve model generalizability. We generalize the successful paradigm of physics-informed learning (PIL) into a more general framework that also includes what we term physics-augmented learning (PAL). PIL and PAL […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Saba Karimeddiny, Thow Min Cham, Daniel C. Ralph, Yunqiu Kelly Luo, | Summary: We adapt Sagnac interferometry for magneto-optic Kerr effect measurements of spin-orbit-torque-induced magnetic tilting in thin-film magnetic samples. The high sensitivity of Sagnac interferometry permits for the first time optical quantification of spin-orbit torque […]
Kavli Affiliate: Wei Gao | First 5 Authors: Hai-Jun Wu, Bing-Shi Yu, Zhi-Han Zhu, Wei Gao, Dong-Sheng Ding | Summary: Vectorial structured light with spatially varying amplitude, phase, and polarization is reshaping many areas of modern optics, including nonlinear optics, as diverse parametric processes can be used to explore interactions between such complex vector fields, […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Melissa Pesce-Rollins, Nicola Omodei, Vahe’ Petrosian, Francesco Longo, | Summary: High-energy solar flares have shown to have at least two distinct phases: prompt-impulsive and delayed-gradual. Identifying the mechanism responsible for accelerating the electrons and ions and the site at which it occurs during these two phases is […]
Kavli Affiliate: Jin Suntivich | First 5 Authors: Oleg Yu. Gorobtsov, Yumeng Song, Kevin Fritz, Daniel Weinstock, Yifei Sun | Summary: Nanostructured proton-conducting ceramics (PCCs) have attracted considerable interest as moderate-temperature proton conductors. Structure dynamics during proton conduction, particularly at grain boundaries, are crucial for stability and proton transport in nanostructured PCCs. A common assumption […]

Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Lars Bildsten, , , | Summary: We calculate the stellar evolution of both white dwarfs (WDs) in AM CVn binaries with orbital periods of $P_{mathrm{orb}} approx 5-70$ minutes. We focus on the cases where the donor starts as a $M_{mathrm{He}} < 0.2 , […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Douglas Tucker, Matthew Wiesner, Sahar Allam, Marcelle Soares-Santos, Clecio de Bom | Summary: On 2019 August 14 at 21:10:39 UTC, the LIGO/Virgo Collaboration (LVC) detected a possible neutron star-black hole merger (NSBH), the first ever identified. An extensive search for an optical counterpart of this event, designated […]
Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Jeffrey Z. Kaaret, Guru Khalsa, Nicole A. Benedek, , | Summary: We use theory and first-principles calculations to investigate how structural changes induced by ultrafast optical excitation of infrared-active phonons change with hydrostatic pressure in LaAlO$_3$. Our calculations show that the observed structural changes are sensitive […]
