The Bruggeman formalism provides an estimate of the effective permittivity of a particulate composite medium comprising two component mediums. The Bruggeman estimate is required to lie within the Wiener bounds and the Hashin–Shtrikman bounds. Considering the homogenization of weakly dissipative component mediums characterized by relative permittivities with real parts of opposite signs, we show...

In this note, we construct Noether charges for the chiral supergravity, which contains the Lorentz Chern–Simons term, by applying Wald’s prescription to the vielbein formalism. We investigate the AdS3/CFT2 correspondence by using the vielbein formalism. The asymptotic symmetry group is carefully examined by taking into account the local Lorentz transformation, and we construct super Virasoro al...

Many-body physics aims to understand emergent properties of systems made many interacting objects. This article reviews recent progress on the topic radiative heat transfer in many-body consisting thermal emitters near-field regime. Near-field is a rapidly emerging field research which cooperative behavior gives rise peculiar effects can be exploited control flow at nanoscale. Using an extensio...
