Origin of high thermal conductivity in disentangled ultra-high molecular weight polyethylene films: ballistic phonons within enlarged crystals

Posted by klaurent Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Taeyong Kim, Stavros X. Drakopoulos, Sara Ronca, Austin J. Minnich, | Summary: The thermal transport properties of oriented polymers are of fundamental and practical interest. High thermal conductivities ($gtrsim 50$ Wm$^{-1}$K$^{-1}$) have recently been reported in disentangled ultra-high molecular weight polyethylene (UHMWPE) films, considerably exceeding prior […]

Electron Pulse Compression with Optical Beat Note

Posted by klaurent Stanford

Kavli Affiliate: Robert L. Byer | First 5 Authors: Zhexin Zhao, Kenneth J. Leedle, Dylan S. Black, Olav Solgaard, Robert L. Byer | Summary: Compressing electron pulses is important in many applications of electron beam systems. In this study, we propose to use optical beat notes to compress electron pulses. The beat frequency is chosen […]

Unveiling the Fermi Bubbles origin with MeV photon telescopes

Posted by klaurent Stanford

Kavli Affiliate: Seth Digel | First 5 Authors: Michela Negro, Henrike Fleischhack, Andreas Zoglauer, Seth Digel, Marco Ajello | Summary: The Fermi Bubbles (FB) are a pair of large-scale ellipsoidal structures extending above and below the Galactic plane almost symmetrically aligned with the Galactic Center. After more than 10 years since their discovery, their nature […]

Long-range, Non-local Switching of Spin Textures in a Frustrated Antiferromagnet

Posted by klaurent Berkeley

Kavli Affiliate: Joel Moore | First 5 Authors: Shannon C. Haley, Eran Maniv, Tessa Cookmeyer, Susana Torres-Londono, Meera Aravinth | Summary: Antiferromagnetic spintronics is an emerging area of quantum technologies that leverage the coupling between spin and orbital degrees of freedom in exotic materials. Spin-orbit interactions allow spin or angular momentum to be injected via […]

Broken Conformal Window

Posted by klaurent Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Hitoshi Murayama, Bea Noether, Digvijay Roy Varier, , | Summary: We show that the edges of the conformal window of supersymmetric $SU(N_c)$ QCD, perturbed by Anomaly Mediated Supersymmetry Breaking (AMSB), break chiral symmetry. We do so by perturbatively expanding around Banks–Zaks fixed points and taking advantage of […]

Evidence for the connection between star formation rate and evolutionary phases of quasars

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhifu Chen, Zhicheng He, Luis C. Ho, Qiusheng Gu, Tinggui Wang | Summary: Both theory and observations suggest that outflows driven by an active central supermassive black hole (SMBH) has a feedback effect on shaping the global properties of the host galaxy. However, whether feedback from […]
