Hamiltonian deformations in quantum mechanics, $Tbar T$, and SYK

Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Motivated by $Tbar T$, we introduce and study a wide class of solvable deformations of quantum-mechanical theories. These deformations map the Hamiltonian to a function of itself. We solve these theories by computing all finite-temperature […]

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 […]
