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
Strain fields generated at the interface of two dissimilar ferroelastic oxides induce a structural cubic-to-tetragonal phase
transition. Using Landau theory for the distrortion of the strain fields we found analytically that the dilatational strain
exhibits compression close to the interface that in turn may affect drastically the electronic properties in the vicinity of the interface.
