Soliton operators in the quantum equivalence of the and models
J Stephany, M. Vollmann
We discuss some interesting aspects of the well known quantum equivalence between the and models in , working in the canonical and in the path integral formulat…
An elementary approach to electromagnetic momentum in matter
Rodrigo Medina, J. Stephany
We present an elementary discussion of the momentum transferred to a conducting sheet by an electromagnetic wave propagating in a polarizable medium. We show that conservation of m…
The force density and the kinetic energy-momentum tensor of electromagnetic fields in matter
Rodrigo Medina, J. Stephany
We determine the invariant expression of the force density that the electromagnetic field exerts on dipolar matter and construct the non-symmetric energy-momentum tensor of the ele…
Violation of the center of mass theorem for systems with electromagnetic interaction
Rodrigo Medina, J. Stephany
In this letter we show that for isolated systems for which the energy current density is not equal to the momentum density, that means for systems with non-symmetric energy-momentu…
On the dynamics of maximum extractable entanglement for open systems
E. Isasi, D. Mundarain, J. Stephany
In this work we study the dynamics of the maximum extractable entanglement for a system composed of two qubits interacting either with two independent thermal baths, a common therm…
Concurrence and negativity as distances
D. Mundarain, J. Stephany
In this report we consider the three dimensional subset of the space of states of two qubits that may be written in the so called standard form. For those states we show that diffe…
