Dynamical localization in 2D topological quantum random walks

Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: We study the dynamical localization of discrete time evolution of topological split-step quantum random walk (QRW) on a single-site defect starting from a uniform distribution. Using analytical and numerical calculations, we determine the high localization probability regions […]

Constant search time algorithm via topological quantum walks

Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: It is well-known that quantum algorithms such as Grover’s can provide a quadradic speed-up for unstructured search problems. By adding topological structure to a search problem, we show that it is possible to achieve a constant search-time […]

Absence of a Correlation between White Dwarf Planetary Accretion and Primordial Stellar Metallicity

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sydney Jenkins, Andrew Vanderburg, Allyson Bieryla, David W. Latham, Mariona Badenas-Agusti | Summary: Over a quarter of white dwarfs have photospheric metal pollution, which is evidence for recent accretion of exoplanetary material. While a wide range of mechanisms have been proposed to account for this pollution, there […]

A Potential Second Shutoff from AT2018fyk: An updated Orbital Ephemeris of the Surviving Star under the Repeating Partial Tidal Disruption Event Paradigm

Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Eric Coughlin, Muryel Guolo, Thomas Wevers, Chris Nixon | Summary: The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypothesized that this behavior results from a repeating partial […]
