Rapid accretion state transitions following the tidal disruption event AT2018fyk

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Dheeraj R. Pasham, Sjoert van Velzen, James C. A. Miller-Jones, Phil Uttley | Summary: Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-Eddington levels and back over months – years timescales. This provides a unique opportunity to study […]

Emergent chirality in a polar meron to skyrmion phase transition

Kavli Affiliate: David A. Muller | First 5 Authors: Yu-Tsun Shao, Sujit Das, Zijian Hong, Ruijuan Xu, Swathi Chandrika | Summary: Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya interaction in magnetic skyrmions. With the discovery of topologically-stable […]

TIC 168789840: A Sextuply-Eclipsing Sextuple Star System

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits, Petr Zasche | Summary: We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three eclipsing binaries. The […]

Quantum Information Theory of the Gravitational Anomaly

Kavli Affiliate: Simeon Hellerman | Summary:We show that the standard notion of entanglement is not defined for gravitationally anomalous two-dimensional theories because they do not admit a local tensor factorization of the Hilbert space into local Hilbert spaces. Qualitatively, the modular flow cannot act consistently and unitarily in a finite region, if there are different […]

Exact uniform modulus of continuity and Chung’s LIL for the generalized fractional Brownian motion

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: The generalized fractional Brownian motion (GFBM) $X:={X(t)}_{tge0}$ with parameters $gamma in [0, 1)$ and $alphain left(-frac12+frac{gamma}{2}, , frac12+frac{gamma}{2} right)$ is a centered Gaussian $H$-self-similar process introduced by Pang and Taqqu (2019) as the scaling limit of power-law shot noise […]
