Kavli Affiliate: Jie Shan | First 5 Authors: Xuhui Li, Xuhui Li, , , | Summary: In the work of N. Martys et al. [Nicos S. Martys, Xiaowen Shan, Hudong Chen, Phys. Rev. E, Vol. 58, Num.5, 1998 ], a self-consistent force term to any order in the Boltzmann-BKG equation is derived by the Hermite […]
Kavli Affiliate: Ankit Disa | Summary:Fluctuating orders in solids are generally considered high-temperature precursors of broken symmetry phases. However, in some cases these fluctuations persist to zero temperature and prevent the emergence of long-range order, as for example observed in quantum spin and dipolar liquids. $SrTiO_3$ is a quantum paraelectric in which dipolar fluctuations grow […]
Kavli Affiliate: Miriam Blaauboer | Summary:We theoretically investigate the enhancement of the charging power in a Dicke quantum battery which consists of an array of $N$ two-level systems (TLS) coupled to a single mode of cavity photons. In the limit of small $N$, we analytically solve the time evolution for the full charging process. The […]
Kavli Affiliate: Mark Schattenburg | Summary:We present measurements of the resolving power of a soft x-ray spectrometer consisting of 200 nm-period lightweight, alignment-insensitive critical-angle transmission (CAT) gratings and a lightweight slumped-glass Wolter-I focusing mirror pair. We measure and model contributions from source, mirrors, detector pixel size, and grating period variation to the natural line width […]
Kavli Affiliate: Eric Peng | First 5 Authors: Eric Emsellem, Remco F. J. van der Burg, Jeremy Fensch, Tereza Jerabkova, Anita Zanella | Summary: The so-called ultra-diffuse galaxy NGC~1052-DF2 was announced to be a galaxy lacking dark matter based on a spectroscopic study of its constituent globular clusters. Here we present the first spectroscopic analysis […]
Kavli Affiliate: Radhika Nagpal | First 5 Authors: Daniel S. Calovi, Paul Bardunias, Nicole Carey, J. Scott Turner, Radhika Nagpal | Summary: Termite colonies construct towering, complex mounds, in a classic example of distributed agents coordinating their activity via interaction with a shared environment. The traditional explanation for how this coordination occurs focuses on the […]
Kavli Affiliate: Rodriguez Enrique Lopez | Summary:We present Far-Infrared polarimetry observations of M82 at 53 and $154~μrmm$ and NGC 253 at $89~μrmm$, which were taken with HAWC+ in polarimetry mode on the Stratospheric Observatory for Infrared Astronomy (SOFIA). The polarization of M82 at $53~μrmm$ clearly shows a magnetic field geometry perpendicular to the disk in […]
Kavli Affiliate: David Weitz | First 5 Authors: Andrea Montessori, Marco Lauricella, Elad Stolovicki, David Weitz, Sauro Succi | Summary: Fully three-dimensional, time-dependent, direct simulations of the non-ideal Navier-Stokes equations for a two-component fluid, shed light into the mechanism which inhibits droplet breakup in step emulsifiers below a critical threshold of the the width-to-height ($w/h$) […]
Kavli Affiliate: Mark Hartz | Summary:This document summarizes the conclusions of the Neutrino Town Meeting held at CERN in October 2018 to review the neutrino field at large with the aim of defining a strategy for accelerator-based neutrino physics in Europe. The importance of the field across its many complementary components is stressed. Recommendations are […]
