Temperedness criterion of the tensor product of parabolic induction for $GL_n$

Posted by klaurent Tokyo

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Yves Benoist, Yui Inoue, Toshiyuki Kobayashi, , | Summary: We give a necessary and sufficient condition for a pair of parabolic subgroups $P$ and $Q$ of $G=GL_n(mathbb{R})$ such that the tensor product of any two unitarily induced representations from $P$ and $Q$ are tempered. We also give […]

Infrared dielectric functions and Brillouin zone center phonons of $α$-Ga$_2$O$_3$ compared to $α$-Al$_2$O$_3$

Posted by klaurent Cornell

Kavli Affiliate: Debdeep Jena | First 5 Authors: Megan Stokey, Rafal Korlacki, Matthew Hilfiker, Sean Knight, Steffen Richter | Summary: We determine the anisotropic dielectric functions of rhombohedral $alpha$-Ga$_2$O$_3$ by far-infrared and infrared generalized spectroscopic ellipsometry and derive all transverse optical and longitudinal optical phonon mode frequencies and broadening parameters. We also determine the high […]

Topological quantum interference in a pumped Su-Schrieffer-Heeger lattice

Posted by Berkeley

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Juan Atalaya, K. Birgitta Whaley, , | Summary: Topological quantum interference emerges from the interplay between quantum mechanics and topology. We present evidence for two types of such interference phenomenon that can result from the quantum dynamics of initial topological states. We realize both […]

Malaise and remedy of binary boson-star initial data

Posted by klaurent Cambridge

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Thomas Helfer, Ulrich Sperhake, Robin Croft, Miren Radia, Bo-Xuan Ge | Summary: Through numerical simulations of boson-star head-on collisions, we explore the quality of binary initial data obtained from the superposition of single-star spacetimes. Our results demonstrate that evolutions starting from a plain superposition of individual boosted […]
