Superconducting quantum oscillations and anomalous negative magnetoresistance in a honeycomb nanopatterned oxide interface superconductor

Posted by dbos April 15, 2025April 28, 2025UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yishuai Wang, Siyuan Hong, Wenze Pan, Yi Zhou, Yanwu Xie | Summary: The extremely low superfluid density and unprecedented tunability of oxide interface superconductors provide an ideal platform for studying fluctuations in two-dimensional superconductors. In this work, we have fabricated a LaAlO3/KTaO3 interface superconductor patterned with a […]

High-Resolution Casimir Force Sensing Across a Superconducting Transition

Posted by klaurent April 14, 2025Delft

Kavli Affiliate: Sander Otte | Summary:The Casimir effect and superconductivity are foundational quantum phenomena whose interplay is an open question in physics, with significant implications for electron physics, quantum gravity, and high-temperature superconductivity. Determining how Casimir forces behave across a superconducting transition remains elusive due to the difficulty of realizing precise alignment, cryogenic operation, and […]

Measuring Casimir Force Across a Superconducting Transition

Posted by klaurent April 14, 2025Delft

Kavli Affiliate: Sander Otte | Summary:The Casimir effect and superconductivity are foundational quantum phenomena whose interaction remains an open question in physics. How Casimir forces behave across a superconducting transition remains unresolved, owing to the experimental difficulty of achieving alignment, cryogenic environments, and isolating small changes from competing effects. This question carries implications for electron […]

Do We Know How to Model Reionization?

Posted by klaurent April 14, 2025Chicago

Kavli Affiliate: Nickolay Gnedin | Summary:I compare the power spectra of the radiation fields from two recent sets of fully coupled simulations that model cosmic reionization: "Cosmic Reionization On Computers" (CROC) and "Thesan". While both simulations have similar power spectra of the radiation sources, the power spectra of the photoionization rate are significantly different at […]

Quantum geometry from the Moyal product: quantum kinetic equation and non-linear response

Posted by klaurent April 14, 2025UCSB

Kavli Affiliate: Leon Balents | Summary:We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-diagonalize the dynamics. Expanding to the second order in gradients, which is beyond the semiclassical limit, we give a complete analysis of the band-resolved thermodynamics and […]

Cosmogenic Neutrino Point Source and KM3-230213A

Posted by klaurent April 14, 2025Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Qinyuan Zhang, Qinyuan Zhang, , , | Summary: Cosmogenic neutrinos (CNs) are produced by ultra-high energy cosmic rays (UHECRs) interacting with cosmic background radiation. We investigated the properties of CN point/extended sources, i.e, the neutrino spectrum, and angular profile as functions of time, by assuming that UHECR […]
