Kavli Affiliate: Wayne Hu | First 5 Authors: Christian Capanelli, Wayne Hu, Evan McDonough, , | Summary: In the Fuzzy Dark Matter (FDM) scenario, the dark matter is composed of an ultra-light scalar field with coherence length and wave interference on astrophysical scales. Scalar fields generically have quartic self-interactions that modify their dispersion relation and […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: A. Lola Danhaive, Sandro Tacchella, Hannah Übler, Anna de Graaff, Eiichi Egami | Summary: Recent studies of gas kinematics at high redshift have reported disky systems which appear to challenge models of galaxy formation, but it is unclear whether they are representative of the underlying galaxy population. […]
Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Juan M. Espejo Salcedo, Stavros Pastras, Josef Vácha, Claudia Pulsoni, Reinhard Genzel | Summary: How radial flows shape galaxy structure and evolution remains an open question. Internal drivers of such flows, such as bars and spiral arms, known to mediate gas flows in the local Universe, are […]
Kavli Affiliate: Paul D. Asimow | First 5 Authors: Junjie Dong, Gabriel-Darius Mardaru, Paul D. Asimow, Lars P. Stixrude, Rebecca A. Fischer | Summary: We present globally inverted pressure-temperature (P-T) phase diagrams up to 5,000 GPa for four fundamental planetary materials, Fe, MgO, SiO2, and MgSiO3, derived from logistic regression and supervised learning, together with […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Jiten Dhandha, Thomas Gessey-Jones, Harry T. J. Bevins, Simon Pochinda, Anastasia Fialkov | Summary: In the current era of JWST, we continue to uncover a wealth of information about the Universe deep into the Epoch of Reionization. In this work, we run a suite of simulations using […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ji Li, Ke Wang, Qiliang Wu, Qing Yu, | Summary: A wave front and a wave back that spontaneously connect two hyperbolic equilibria, known as a heteroclinic wave loop, give rise to periodic waves with arbitrarily large spatial periods through the heteroclinic bifurcation. The nonlinear stability of […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Luigi Pacciani, Dawoon E. Kim, Riccardo Middei, Herman L. Marshall, Alan P. Marscher | Summary: We report the Imaging X-ray Polarimetry Explorer (IXPE) polarimetric and simultaneous multiwavelength observations of the high-energy-peaked BL Lacertae (HBL) object 1ES 1959+650, performed in 2022 October and 2023 August. In 2022 […]
Kavli Affiliate: Jia Liu | First 5 Authors: Changqing Li, Ran Xia, Yutai Zhao, Yifang Li, Jia Liu | Summary: Mamyshev oscillators (MOs), a novel class of passively mode-locked fiber lasers, serve as an excellent platform to explore complex nonlinear dynamics, ranging from localized sturctures to chaos. Despite their versatility, achieving self-starting mode-locking remains a […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term quantum chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Haoyang Qi, Renxin Xu, , , | Summary: This article discusses strong nuggets (SNs) which means strong interaction condensed matter clusters with a mass of about $10^6,$g. They may originate from the early universe, supernova, pulsar merger event, and so on. Depending on the equation of state, […]
