Observation of spin-momentum locked surface states in amorphous Bi$_{2}$Se$_{3}$

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: , , , , | Summary: Crystalline symmetries have played a central role in the identification of topological materials. The use of symmetry indicators and band representations have enabled a classification scheme for crystalline topological materials, leading to large scale topological materials discovery. In this work we […]

Modification of electron-phonon coupling by micromachining and suspension

Kavli Affiliate: Michael Roukes | First 5 Authors: Olli-Pentti Saira, Matthew H. Matheny, Libin Wang, Jukka Pekola, Michael Roukes | Summary: Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing the heat flow in the majority of experiments, have been identified […]

Elastic properties of hidden order in URu$_{text2}$Si$_{text2}$ are reproduced by a staggered nematic

Kavli Affiliate: Brad Ramshaw | First 5 Authors: Jaron Kent-Dobias, Michael Matty, Brad Ramshaw, , | Summary: We develop a phenomenological mean field theory describing the hidden order phase in URu$_{text2}$Si$_{text2}$ as a nematic of the $text B_{text{1g}}$ representation staggered along the $c$-axis. Several experimental features are reproduced by this theory: the topology of the […]

Nonequilibrium thermodynamics of erasure with superconducting flux logic

Kavli Affiliate: Michael L. Roukes | First 5 Authors: Olli-Pentti Saira, Matthew H. Matheny, Raj Katti, Warren Fon, Gregory Wimsatt | Summary: We implement a thermal-fluctuation driven logical bit reset on a superconducting flux logic cell. We show that the logical state of the system can be continuously monitored with only a small perturbation to […]

Independence Testing for Temporal Data

Kavli Affiliate: Ting Xu | First 5 Authors: Cencheng Shen, Jaewon Chung, Ronak Mehta, Ting Xu, Joshua T. Vogelstein | Summary: Temporal data are increasingly prevalent in modern data science. A fundamental question is whether two time-series are related or not. Existing approaches often have limitations, such as relying on parametric assumptions, detecting only linear […]
