Machine-Learning Non-Conservative Dynamics for New-Physics Detection

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Bohan Wang, Qi Meng, Wei Chen, Max Tegmark | Summary: Energy conservation is a basic physics principle, the breakdown of which often implies new physics. This paper presents a method for data-driven "new physics" discovery. Specifically, given a trajectory governed by unknown forces, our Neural […]

Earth as a transducer for dark-photon dark-matter detection

Kavli Affiliate: Peter W. Graham | First 5 Authors: Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia, | Summary: We propose the use of the Earth as a transducer for ultralight dark-matter detection. In particular we point out a novel signal of kinetically mixed dark-photon dark matter: a monochromatic oscillating magnetic […]

Testing the SZ-based tomographic approach to the thermal history of the universe with pressure-density cross-correlations: Insights from the Magneticum simulation

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Sam Young, Eiichiro Komatsu, Klaus Dolag, , | Summary: The thermal Sunyaev-Zeldovich effect contains information about the thermal history of the universe, observable in maps of the Compton $y$ parameter; however, it does not contain information about the redshift of the sources. Recent papers have utilized a […]

Merging timescale for supermassive black hole binary in interacting galaxy NGC 6240

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Margarita Sobolenko, Peter Berczik, Rainer Spurzem, , | Summary: One of the main possible way of creating the supermassive black hole (SMBH) is a so call hierarchical merging scenario. Central SMBHs at the final phase of interacting and coalescing host-galaxies are observed as SMBH binary (SMBHB) candidates […]

Structural Origins of Cartilage Shear Mechanics

Kavli Affiliate: Itai Cohen | First 5 Authors: Thomas Wyse Jackson, Jonathan Michel, Pancy Lwin, Lisa A. Fortier, Moumita Das | Summary: Healthy cartilage is a remarkable tissue, able to withstand tens of millions of loading cycles with minimal damage. While much is known about the structural origins of its compressive mechanics, how composition determines […]

Nickelate superconductivity without rare-earth magnetism: (La,Sr)NiO$_{2}$

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Motoki Osada, Bai Yang Wang, Berit H. Goodge, Shannon P. Harvey, Kyuho Lee | Summary: The observation of superconductivity in infinite layer nickelate (Nd,Sr)NiO$_{2}$ thin films has led to rapid theoretical and experimental investigations of these copper-oxide-analogue systems [1-15]. Superconductivity has also been found in (Pr,Sr)NiO$_{2}$ […]

Entanglement Domain Walls in Monitored Quantum Circuits and the Directed Polymer in a Random Environment

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Sagar Vijay, Matthew P. A. Fisher, , | Summary: Monitored quantum dynamics reveal quantum state trajectories which exhibit a rich phenomenology of entanglement structures, including a transition from a weakly-monitored volume law entangled phase to a strongly-monitored area law phase. For one-dimensional hybrid […]

Renormalization and non-renormalization of scalar EFTs at higher orders

Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Franz Herzog, Tom Melia, Jasper Roosmale Nepveu, | Summary: We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series […]
