Exciton Condensation in Landau Levels of Quantum Spin Hall Insulators

Kavli Affiliate: Long Zhang | First 5 Authors: Hong-Mao Peng, Zhan Wang, Long Zhang, , | Summary: We theoretically study the quantum spin Hall insulator (QSHI) in a perpendicular magnetic field. In the noninteracting case, the QSHI with space inversion and/or uniaxial spin rotation symmetry undergoes a topological transition into a normal insulator phase at […]

Hyperspectral unmixing for Raman spectroscopy via physics-constrained autoencoders

Kavli Affiliate: Molly Stevens | Summary:Raman spectroscopy is widely used across scientific domains to characterize the chemical composition of samples in a non-destructive, label-free manner. Many applications entail the unmixing of signals from mixtures of molecular species to identify the individual components present and their proportions, yet conventional methods for chemometrics often struggle with complex […]

Finite final segments of the d.c.e. Turing degrees

Kavli Affiliate: Cheng Peng | First 5 Authors: Steffen Lempp, Yiqun Liu, Yong Liu, Keng Meng Ng, Cheng Peng | Summary: We prove that every finite distributive lattice is isomorphic to a final segment of the d.c.e. Turing degrees (i.e., the degrees of differences of computably enumerable sets). | Search Query: ArXiv Query: search_query=au:”Cheng Peng”&id_list=&start=0&max_results=3 […]

Witt’s hyperbola is both predicted and observed to pass close to the lensing galaxies in quadruple quasars

Kavli Affiliate: Paul Schechter | Summary:When a rectangular hyperbola is constructed from the image positions of a quadruply lensed quasar, as proposed by Witt (1996), it passes very close to the the lensing galaxy. The median measured perpendicular offset between the observed light center of the lens and Witt’s hyperbola is 0.013" for a sample […]
