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 […]

Dissipation-enabled hydrodynamic conductivity in a tunable bandgap semiconductor

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Cheng Tan, Derek Y. H. Ho, Lei Wang, J. I. A. Li, Indra Yudhistira | Summary: Electronic transport in the regime where carrier-carrier collisions are the dominant scattering mechanism has taken on new relevance with the advent of ultraclean two-dimensional materials. Here we present a combined […]

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 […]

Entanglement, squeezing and state-swap in cholesteric liquid crystals

Kavli Affiliate: Ya M. Blanter | First 5 Authors: J. D. P. Machado, Ya. M. Blanter, , , | Summary: Phenomena such as state-swap, quadrature squeezing, entanglement and violation of entanglement inequalities are frequently reported to occur in quantum systems only. It is shown here that these effects can also occur in cholesteric liquid crystals […]

Spontaneous Domain Formation in Spherically-Confined Elastic Filaments

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Tine Curk, James Daniel Farrell, Jure Dobnikar, Rudolf Podgornik, | Summary: Although the free energy of a genome packing into a virus is dominated by DNA-DNA interactions, ordering of the DNA inside the capsid is elasticity-driven, suggesting general solutions with DNA organized into spool-like domains. Using analytical […]
