Indirect Probe of Electroweak-Interacting Particles at $μ$TRISTAN $μ^+μ^+$ Collider

Posted by dbos Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Risshin Okabe, Satoshi Shirai, , , | Summary: Recently, a novel collider, called $mu$TRISTAN, has been proposed, offering the capability to achieve high-energy collisions of anti-muons. This high-energy collider presents an exceptional opportunity for the discovery of electroweak-interacting massive particles (EWIMPs), which are predicted by various new […]

Characterizing Floquet topological phases by quench dynamics: A multiple-subsystem approach

Posted by dbos October 12, 2023UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Bei-Bei Wang, Long Zhang, , , | Summary: We investigate the dynamical characterization theory for periodically driven systems in which Floquet topology can be fully detected by emergent topological patterns of quench dynamics in momentum subspaces called band-inversion surfaces. We improve the results of a recent work […]

Phonon vortices at heavy impurities in two-dimensional materials

Posted by dbos October 12, 2023UCAS

Kavli Affiliate: Gang Su | First 5 Authors: De-Liang Bao, Mingquan Xu, Ao-Wen Li, Gang Su, Wu Zhou | Summary: The advent of monochromated electron energy-loss spectroscopy has enabled atomic-resolution vibrational spectroscopy, which triggered interest in spatially localized or quasi-localized vibrational modes in materials. Here we report the discovery of phonon vortices at heavy impurities […]

A High-Mass Young Star-forming Core Escaping from Its Parental Filament

Posted by dbos October 12, 2023October 23, 2023Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Zhiyuan Ren, , , , | Summary: We studied the unique kinematic properties in massive filament G352.63-1.07 at $10^3$-AU spatial scale with the dense molecular tracers observed with the Atacama Large Millimeter/submillimeter Array (ALMA). We find the central massive core M1 (12 $M_odot$) being separated from the […]

Spin and Valley Polarized Multiple Fermi Surfaces of α-RuCl$_3$/Bilayer Graphene Heterostructure

Posted by dbos Caltech

Kavli Affiliate: Joseph Falson | First 5 Authors: Soyun Kim, Jeonghoon Hong, Kenji Watanabe, Takashi Taniguchi, Joseph Falson | Summary: We report the transport properties of ${alpha}$-RuCl$_3$/bilayer graphene heterostructures, where carrier doping is induced by a work function difference, resulting in distinct electron and hole populations in ${alpha}$-RuCl3 and bilayer graphene, respectively. Through a comprehensive […]
