Diffusive dynamics of charge regulated macro-ion solutions

Posted by dbos UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Bin Zheng, Shigeyuki Komura, David Andelman, Rudolf Podgornik, | Summary: Onsager’s variational principle is generalized to address the diffusive dynamics of an electrolyte solution composed of charge-regulated macro-ions and counterions. The free energy entering the Rayleighian corresponds to the Poisson-Boltzmann theory augmented by the charge-regulation mechanism. The […]

Cancelling mod-2 anomalies by Green-Schwarz mechanism with $B_{μν}$

Posted by dbos Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Shota Saito, Yuji Tachikawa, , , | Summary: We study if and when mod-2 anomalies can be canceled by the Green-Schwarz mechanism with the introduction of an antisymmetric tensor field $B_{munu}$. As explicit examples, we examine $SU(2)$ and more general $Sp(n)$ gauge theories in four and eight […]

Symmetry-Agnostic Topology Optimization Framework for Photonic-Crystal Structures

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Aditya Bahulikar, Feng Wang, Mustafa Cenk Gursoy, Rodrick Kuate Defo, | Summary: We present a symmetry-agnostic topology optimization framework for photonic-crystal structures based on computation of the photonic density of states in a manner analogous to $Gamma$-point integration. We provide a generalization of the approach that allows […]

Coherently Coupled Carrier and Phonon Dynamics in Elemental Tellurium Probed by Few-Femtosecond Core-Level Transient Absorption

Posted by dbos Berkeley

Kavli Affiliate: Peidong Yang | First 5 Authors: Jonah R. Adelman, Hugo Laurell, Lorenz Drescher, Han K. D. Le, Peidong Yang | Summary: The narrow bandgap semiconductor elemental tellurium (Te) has a unique electronic structure due to strong spin-orbit splitting and a lack of inversion symmetry of its helical lattice. Using broadband extreme ultraviolet core-level […]

$S^5$: New insights from deep spectroscopic observations of the tidal tails of the globular clusters NGC 1261 and NGC 1904

Posted by dbos Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Petra Awad, Ting S. Li, Denis Erkal, Reynier F. Peletier, Kerstin Bunte | Summary: As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of these tails is […]

The THESAN project: tracking the expansion and merger histories of ionized bubbles during the Epoch of Reionization

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nathan Jamieson, Aaron Smith, Meredith Neyer, Rahul Kannan, Enrico Garaldi | Summary: The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we analyze bubble sizes and their evolution using […]
