Casimir forces in multilayer magnetodielectrics with both gain and loss

Abstract: A path-integral approach to the quantization of the electromagnetic field in a linearly amplifying magnetodielectric medium is presented. Two continua of inverted harmonic oscillators are used to describe the polarizability and magnetizability of the amplifying medium. The causal susceptibilities of the amplifying medium, with negative imaginary parts in finite frequency intervals, are identified and their relation to microscopic coupling functions are determined. By carefully relating the twopoint functions o… Show more

“…This kind of heat bath could be a model for an elastic solid, a dissipative medium and electromagnetic field that known as the Hopfield model [50]. This model can be also used to describe the quantization of electromagnetic field in presence of an amplifying magnetodielectric medium [51] where the electric and magnetic properties of the medium are modeled by two independent sets of harmonic oscillators. In order to examine the classical and the quantum treatment of a linear dissipative system, we start the following classical Lagrangian for the total system…”

“…Complementary strategies are to replace the metals by other material [3] or to compensate for the metal loss [4][5][6][7][8]. As an important branch of active plasmonics [9], active loss compensation with the use of gain material has already proved experimentally successful, for example in surface plasmon polariton propagation [10,11] and in metamaterials [12].In recent years the quantum optics of attenuating [13][14][15][16][17][18][19] and amplifying [20][21][22][23][24] dielectric media was developed, where optical modes are described as open quantum systems. There are important similarities with classical optics, for example the classical Green function plays a central role also in quantum optics, but new is that both with loss and gain there is quantum noise associated.…”
