Abelian envelopes of exact categories and highest weight categories

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define admissible and weakly admissible subcategories in exact categories and prove that the former induce semi-orthogonal decompositions on the derived categories. We develop the theory of thin exact categories, an exact-category analogue of triangulated categories generated by exceptional […]

Path-Dependent Supercooling of the $^3$He Superfluid A-B transition

Kavli Affiliate: Jeevak Parpia | First 5 Authors: Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev, Abhilash Sebastian, Yefan Tian | Summary: We examine the discontinuous first-order superfluid $^3$He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions: cooling at fixed pressure yields a well defined […]

Direct Observation of Thermalization to a Rayleigh-Jeans Distribution in Multimode Optical Fibers

Kavli Affiliate: Frank Wise | First 5 Authors: Hamed Pourbeyram, Pavel Sidorenko, Fan Wu, Nicholas Bender, Logan Wright | Summary: Recent years have witnessed a resurgence of interest in nonlinear multimode optical systems where a host of intriguing effects have been observed that are impossible in single-mode settings. While nonlinearity can provide a rich environment […]

X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary

Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]

Bloch-Lorentz magnetoresistance oscillations in delafossites

Kavli Affiliate: Anton Akhmerov | First 5 Authors: Kostas Vilkelis, Lin Wang, Anton Akhmerov, , | Summary: Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO$_2$ and PtCoO$_2$) observed oscillations closely resembling the Aharonov-Bohm effect. Here, we show that the magnetoresistance oscillations are explained by the Bloch-like oscillations of the out-of-plane electron trajectories. We develop […]

Elliptical accretion disk as a model for tidal disruption events

Kavli Affiliate: Fukun Liu | First 5 Authors: Fukun Liu, Chunyang Cao, Marek A. Abramowicz, Maciek Wielgus, Rong Cao | Summary: Elliptical accretion disk models for tidal disruption events (TDEs) have been recently proposed and independently developed by two groups. Although these two models are characterized by a similar geometry, their physical properties differ considerably. […]
