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: The interplay of band topology and electron interactions can lead to novel quantum states of matter. In this work, we theoretically study the quantum spin Hall insulator (QSHI) in a perpendicular magnetic field. In the noninteracting case, the […]

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

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | 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 […]

Galaxies lensing quadruply imaged quasars lie close to the centers of their lensing potentials

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: In modeling the potentials of quadruply lensed quasars, investigators often employ models for the stellar surface brightness profile of the lensing galaxy for the sole purpose of eliminating its contamination of the light from the quasar images […]
