PT -symmetric nonlinear metamaterials and zero-dimensional systems
A one dimensional, parity-time (PT )-symmetric magnetic metamaterial comprising split-ring resonators having both gain and loss is investigated. In the linear regime, the transition from the exact to the broken PT -phase is determined through the calculation of the eigenfrequency spectrum for two different configurations; the one with equidistant split-rings and the other with the split-rings f...

متن کاملPerturbed Defects and T-Systems in Conformal Field Theory
Defect lines in conformal field theory can be perturbed by chiral defect fields. If the unperturbed defects satisfy su(2)-type fusion rules, the operators associated to the perturbed defects are shown to obey functional relations known from the study of integrable models as T-systems. The procedure is illustrated for Virasoro minimal models and for Liouville theory. Email: [email protected]
متن کاملThe search for the exotic — subfactors and conformal field theories
We look at the construction of conformal field theories and their modular invariants via tools from subfactor theory.
متن کاملConformal Vector Fields in Symmetric and Conformal Symmetric Spaces
Consequences of the existence of conformal vector fields in (locally) symmetric and conformal symmetric spaces, have been obtained. An attempt has been made for a physical interpretation of the consequences in the framework of general relativity.
