Thermal transitions in a one-dimensional, finite-size Ising model
Varazdat Stepanyan, Andreas F. Tzortzakakis, David Petrosyan +1
We revisit the one-dimensional ferromagnetic Ising spin-chain with a finite number of spins and periodic boundaries and derive analytically and verify numerically its various stati…
Energy densities in quantum mechanics
V. Stepanyan, A. E. Allahverdyan
Quantum mechanics does not provide any ready recipe for defining energy density in space, since the energy and coordinate do not commute. To find a well-motivated energy density, w…
Photon cooling: linear vs nonlinear interactions
A. Hovhannisyan, V. Stepanyan, A. E. Allahverdyan
Linear optics imposes a relation that is more general than the second law of thermodynamics: For modes undergoing a linear evolution, the full mean occupation number (i.e. photon n…
