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 […]
