Proposal for a shared transverse LLP detector for FCC-ee and FCC-hh and a forward LLP detector for FCC-hh

Posted by klaurent Tokyo

Kavli Affiliate: Shigeki Matsumoto | Summary:As the particle physics community has explored most of the conventional avenues for new physics, the more elusive areas are becoming increasingly appealing. One such potential region, where new physics might be hiding, involves light and weakly interacting long-lived particles (LLPs). To probe deeper into this region, where the possibility […]

Galaxy morphologies at cosmic noon with JWST: A foundation for exploring gas transport with bars and spiral arms

Posted by klaurent Peking

Kavli Affiliate: Jinyi Shangguan | Summary:The way in which 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 now observable at high redshift thanks to JWST’s unobscured view. We investigated the morphology […]

Structure and Melting of Fe, MgO, SiO2, and MgSiO3 in Planets: Database, Inversion, and Phase Diagram

Posted by klaurent Caltech

Kavli Affiliate: Paul D. Asimow | 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 an experimental phase equilibria database. These new P-T phase diagrams provide a solution to long-standing disputes about their […]

Exploiting synergies between JWST and cosmic 21-cm observations to uncover star formation in the early Universe

Posted by klaurent Cambridge

Kavli Affiliate: George Efstathiou | 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 use a suite of simulations with 21cmSPACE, to explore the astrophysical properties of early galaxies and their imprint on high-redshift observables. Our analysis […]

Nonlinear Stability of Large-Period Traveling Waves Bifurcating from the Heteroclinic Loop in the FitzHugh-Nagumo Equation

Posted by klaurent Peking

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 […]

Timing-injection locking in a self-starting Mamyshev oscillator induced by the dissipative Faraday instability

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Changqing Li, Changqing Li, , , | 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 structures to chaos. Despite their versatility, achieving self-starting mode-locking remains a significant challenge. In this […]

Exponential quantum speedups for near-term molecular electronic structure methods

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | Summary:We prove classical simulation hardness, under the generalized $mathsfPneqmathsfNP$ conjecture, for quantum circuit families with applications in near-term chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state inputs, which are shown to be universal for quantum computation under post-selection, and […]
