Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Miren Radia, Ulrich Sperhake, Amelia Drew, Katy Clough, Pau Figueras | Summary: We demonstrate the flexibility and utility of the Berger-Rigoutsos Adaptive Mesh Refinement (AMR) algorithm used in the open-source numerical relativity code GRChombo for generating gravitational waveforms from binary black-hole inspirals, and for studying other problems […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kazuyoshi Miyazaki, Kai Murai, Hiromasa Nakatsuka, Eisuke Sonomoto | Summary: Ultra-light axion-like particle (ULAP) with mass $m sim 10^{-22} ~mathrm{eV}$ has recently been attracting attention as a possible solution to the small-scale crisis. ULAP forms quasi-stable objects called oscillons/I-balls, which can survive up to a […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Adrian T. K. Tan, Shi-Ning Sun, Ruslan N. Tazhigulov, Garnet Kin-Lic Chan, Austin J. Minnich | Summary: The realization of novel phases of matter on quantum simulators is a topic of intense interest. Digital quantum computers offer a route to prepare topological phases with interactions that […]
Kavli Affiliate: Feng Wang | First 5 Authors: Lianmeng Jiao, Feng Wang, Zhun-ga Liu, Quan Pan, | Summary: As a representative evidential clustering algorithm, evidential c-means (ECM) provides a deeper insight into the data by allowing an object to belong not only to a single class, but also to any subset of a collection of […]
Kavli Affiliate: Feng Wang | First 5 Authors: Lianmeng Jiao, Feng Wang, Zhun-ga Liu, Quan Pan, | Summary: Clustering is widely used in text analysis, natural language processing, image segmentation, and other data mining fields. As a promising clustering algorithm, the evidential c-means (ECM) can provide a deeper insight on the data by allowing an […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We reconsider the status of the so-called second clock effect in Weyl gauge theories of gravity, which are invariant both under local Poincar’e transformations and local changes of scale. In particular, we revisit and extend our previous demonstration that […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Ariel Arza, Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia | Summary: We demonstrate that ultralight axion dark matter with a coupling to photons induces an oscillating global terrestrial magnetic field signal in the presence of the background geomagnetic field of the […]
Kavli Affiliate: Giordano Scappucci | First 5 Authors: Brian Paquelet Wuetz, Merritt P. Losert, Sebastian Koelling, Lucas E. A. Stehouwer, Anne-Marije J. Zwerver | Summary: Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction band valleys, which compete with the spin degree of freedom in the formation of qubits. Despite attempts to enhance […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Viktoria Kungel, Randy Bachman, Jerod Brewster, Madeline Dawes, Julianna Desiato | Summary: The Extreme Universe Space Observatory – Super Pressure Balloon (EUSO-SPB2) mission will fly two custom telescopes that feature Schmidt optics to measure v{C}erenkov- and fluorescence-emission of extensive air-showers from cosmic rays at the PeV […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Changhua Bao, Haoyuan Zhong, Shaohua Zhou, Runfa Feng, Yuan Wang | Summary: Time- and angle-resolved photoemission spectroscopy (TrARPES) is a powerful technique for capturing the ultrafast dynamics of charge carriers and revealing photo-induced phase transitions in quantum materials. However, the lack of widely tunable probe photon energy, […]
