Diffusive dynamics of charge regulated macro-ion solutions

Posted by dbos This Week: Theoretical Physics, 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 […]

Flat-space limit of defect correlators and stringy AdS form factors

Posted by dbos UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Xinan Zhou, , , | Summary: We study AdS form factors, given by the Mellin representation for CFT correlators of local operators in the presence of extended defects. We propose a formula for taking (and expanding around) the flat-space limit. This formula relates the […]
