Note on the absence of the second clock effect in Weyl gauge theories of gravity

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 […]

Earth as a transducer for axion dark-matter detection

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 […]

Atomic fluctuations lifting the energy degeneracy in Si/SiGe quantum dots

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 […]

Ultrafast time- and angle-resolved photoemission spectroscopy with widely tunable probe photon energy of 5.3-7.0 eV for investigating dynamics of three-dimensional materials

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, […]

Disordered vector models: from higher spins to incipient strings

Kavli Affiliate: Cheng Peng | First 5 Authors: Chi-Ming Chang, Sean Colin-Ellerin, Cheng Peng, Mukund Rangamani, | Summary: We present a one-parameter family of large $N$ disordered models, with and without supersymmetry, in three spacetime dimensions. They interpolate from the critical large $N$ vector model dual to a classical higher spin theory, towards a theory […]
