Abstract: Causality constraints are known to bind sound absorption to a limit that can only be achieved by optimizing the system bandwidth for a specific material thickness. This limit is defined on the assumption of a… read more here.

Abstract: We generalize the convex duality symmetry in Gibbs’ statistical ensemble formulation, between the Gibbs entropy φV,N(E) as a function of mean internal energy E and Massieu’s free entropy ΨV,N(β) as a function of inverse temperature… read more here.

Abstract: The magnetic field driven superconductor to insulator transition in thin films was theoretically analyzed via a vortex-charge duality transformation applied to the Hamiltonian. Vortices condensation was conjectured as the underline physical mechanism of the insulating… read more here.
