Kavli Affiliate: Jia Liu | First 5 Authors: , , , , | Summary: We investigate a fifth force mediated by a light vector boson that couples to lepton spins, characterized by axial-vector couplings to leptons and vector couplings to nucleons. This interaction generates a potential proportional to the inner product of the lepton spin […]
Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Rohit Mukherjee, Haoyu Guo, Debanjan Chowdhury, , | Summary: Periodically driven Floquet quantum many-body systems have revealed new insights into the rich interplay of thermalization, and growth of entanglement. The phenomenology of dynamical freezing, whereby a translationally invariant many-body system exhibits emergent conservation laws and a slow […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Marcela Carena, , , | Summary: Motivated by the out-of-equilibrium dynamics during an early-universe first-order phase transition, we perform real-time simulations of fermion-bubble scattering in $1+1$ dimensions. This nonequilibrium process can generate a charge-conjugation $mathsfC$ asymmetry outside the bubble wall, induced by the complex fermion […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Ying-Ying Li, Tong Ou, Hersh Singh, | Summary: We perform real-time simulation of fermion-bubble scattering during a first order phase transition by which the fermions become massive. This out-of-equilibrium dynamics can generate a CP asymmetry, which is a crucial ingredient for baryon asymmetry generation in […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuta Sekino, Yuya Ominato, Hiroyuki Tajima, Shun Uchino, Mamoru Matsuo | Summary: We study magnon-driven spin and heat transport in a magnetic linear junction (MLJ) formed by two ferromagnets in optical lattices linked via linearly aligned bonds. Using the Schwinger-Keldysh formalism, we uncover that under weak effective […]

Kavli Affiliate: Jie Shan | First 5 Authors: Xiangxi Tian, Jie Shan, , , | Summary: Generating continuous environmental models from sparsely sampled data is a critical challenge in spatial modeling, particularly for topography. Traditional spatial interpolation methods often struggle with handling sparse measurements. To address this, we propose a Transformer-based Generative Model for Spatial […]
Kavli Affiliate: Eiman Azim | Authors: Jake Lustig, Alexander Lammers, Julia Kaiser, Payal Patel, Aidan Raghu, James M. Conner, Phong Nguyen, Eiman Azim and Vibhu Sahni | Summary: The corticospinal tract (CST) facilitates skilled, precise movements, which necessitates that subcerebral projection neurons (SCPN) establish segmentally specific connectivity with brainstem and spinal circuits. Developmental molecular delineation […]
Kavli Affiliate: Brian Van Klaveren | First 5 Authors: Jeremy McCormick, Gregory P. Dubois-Felsmann, Andrei Salnikov, Brian Van Klaveren, Tim Jenness | Summary: The Data Management team of the Vera C. Rubin Observatory has developed a data description language and toolset, Felis, for defining the semantics and metadata of its public-facing data catalogs. Felis uses […]
Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Fabien Defrance, Andrew D. Beyer, Jordan Wheeler, Jack Sayers, Sunil R. Golwala | Summary: At sub-Kelvin temperatures, two-level systems (TLS) present in amorphous dielectrics source a permittivity noise, degrading the performance of a wide range of devices using superconductive resonators such as qubits or kinetic inductance […]
