Optimal Photodetector Size for High-Speed Free-Space Optics Receivers

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Muhammad Salman Bashir, Qasim Zeeshan Ahmed, Mohamed-Slim Alouini, , | Summary: The selection of an optimal photodetector area is closely linked to the attainment of higher data rates in optical wireless communication receivers. If the photodetector area is too large, the channel capacity degrades due to lower […]

What can galaxy shapes tell us about physics beyond the standard model?

Kavli Affiliate: David N. Spergel | First 5 Authors: Oliver H. E. Philcox, Morgane J. König, Stephon Alexander, David N. Spergel, | Summary: The shapes of galaxies trace scalar physics in the late-Universe through the large-scale gravitational potential. Are they also sensitive to higher-spin physics? We present a general study into the observational consequences of […]

Sympathetic Mechanism for Vibrational Condensation Enabled by Polariton Optomechanical Interaction

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Vladislav Yu. Shishkov, Evgeny S. Andrianov, Sergei Tretiak, K. Birgitta Whaley, Anton V. Zasedatelev | Summary: We demonstrate a macro-coherent regime in exciton-polariton systems, where nonequilibrium polariton Bose–Einstein condensation coexists with macroscopically occupied vibrational states. Strong exciton-vibration coupling induces an effective optomechanical interaction between cavity polaritons and […]

Mapping polariton Bose–Einstein condensate onto vibrational degrees of freedom

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Vladislav Yu. Shishkov, Evgeny S. Andrianov, Sergei Tretiak, K. Birgitta Whaley, Anton V. Zasedatelev | Summary: We demonstrate a macro-coherent regime in molecular exciton-polariton systems, where nonequilibrium polariton Bose–Einstein condensation coexists with macroscopically occupied vibrational states. Strong vibronic coupling in molecules induces an effective optomechanical interaction between […]

Topological K-theory of quasi-BPS categories of symmetric quivers with potential

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: In previous works, we introduced and studied certain categories called quasi-BPS categories associated to symmetric quivers with potential, preprojective algebras, and local surfaces. They have properties reminiscent of BPS invariants/ cohomologies in enumerative geometry, for example they play important […]

Gravitational Wave Measurement in the Mid-Band with Atom Interferometers

Kavli Affiliate: Peter W. Graham | First 5 Authors: Sebastian Baum, Zachary Bogorad, Peter W. Graham, , | Summary: Gravitational Waves (GWs) have been detected in the $sim$100 Hz and nHz bands, but most of the gravitational spectrum remains unobserved. A variety of detector concepts have been proposed to expand the range of observable frequencies. […]

Particle-hole asymmetric ferromagnetism and spin textures in the triangular Hubbard-Hofstadter model

Kavli Affiliate: Cheng Peng | First 5 Authors: Jixun K. Ding, Luhang Yang, Wen O. Wang, Ziyan Zhu, Cheng Peng | Summary: In a lattice model subject to a perpendicular magnetic field, when the lattice constant is comparable to the magnetic length, one enters the "Hofstadter regime," where continuum Landau levels become fractal magnetic Bloch […]

Transient Corotating Clumps Around Adolescent Low-Mass Stars From Four Years of TESS

Kavli Affiliate: Saul Rappaport | First 5 Authors: Luke G. Bouma, Rahul Jayaraman, Saul Rappaport, Luisa M. Rebull, Lynne A. Hillenbrand | Summary: Complex periodic variables (CPVs) are stars that exhibit highly structured and periodic optical light curves. Previous studies have indicated that these stars are typically disk-free pre-main-sequence M dwarfs with rotation periods ranging […]
