Kavli Affiliate: Robert M. Wald | First 5 Authors: , , , , | Summary: We consider an experimentalist, Alice, who creates a quantum superposition of a charged or massive body outside of a black hole (or, more generally, in the presence of a Killing horizon). It was previously shown that emission of soft photons/gravitons […]
Kavli Affiliate: Ran Wang | First 5 Authors: Bin Qian, Bin Qian, , , | Summary: Consider the nonlinear stochastic heat equation $$ fracpartial u (t,x)partial t=fracpartial^2 u (t,x)partial x^2+ sigma(u (t,x))dotW(t,x),quad t> 0,, xin mathbbR, $$ where $dot W$ is a Gaussian noise which is white in time and has the covariance of a […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Muryel Guolo, Sean Lockwood, Andrew Mummery, Dheeraj R. Pasham | Summary: X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maxim Chernodub, Maxim Chernodub, , , | Summary: We argue that rotation of a thin superconducting cylinder in the presence of a magnetic field can increase the critical temperature of the superconducting phase transition substantially. The phenomenon originates from interaction energy of the dipole magnetic moment of […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Megan Masterson, , , | Summary: Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the newly-discovered quasi-periodic eruptions (QPEs), are garnering further interest in […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: , , , , | Summary: Primordial black holes (PBHs) can form from gravitational collapse of large overdensities in the early Universe, giving rise to rich phenomena in astrophysics and cosmology. We develop a novel, general, and systematic method based on theory of density contrast peaks to […]
Kavli Affiliate: Jia Liu | First 5 Authors: , , , , | Summary: We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is designed to operate in multiple modes to address a variety of tasks. At the […]
Kavli Affiliate: Jing Wang | First 5 Authors: Kejie Bao, Kejie Bao, , , | Summary: Experimental studies on moir’e materials have predominantly focused on twisted hexagonal lattice with low-energy states near the $Gamma$- or K-points, where the electronic dispersion is typically isotropic. In contrast, we introduce a class of semiconducting transition metal carbides (MXenes) […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Keiichi Watanabe, , | Summary: The Froggatt-Nielsen (FN) mechanism successfully explains the hierarchical structure of fermion Yukawa couplings by introducing a U(1) flavor symmetry with distinct charge assignments for different fermion generations. While some FN charge assignments have been proposed, their evaluation has […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Weijie Lyu, Weijie Lyu, , , | Summary: We present FaceLift, a novel feed-forward approach for generalizable high-quality 360-degree 3D head reconstruction from a single image. Our pipeline first employs a multi-view latent diffusion model to generate consistent side and back views from a single facial input, […]
