Effective damping in the Raman cooling of trapped ions
A. B. Klimov, J. L. Romero, J. Delgado +1
We present a method of treating the interaction of a single three-level ion with two laser beams. The idea is to apply a unitary transformation such that the exact transformed Hami…
Diverging Entanglement Length in Gapped Quantum Spin Systems
F. Verstraete, M. A. Martin-Delgado, J. I. Cirac
We prove the existence of gapped quantum Hamiltonians whose ground states exhibit an infinite entanglement length, as opposed to their finite correlation length. Using the concept…
Inequivalent classes of closed three-level systems
Andre B. Klimov, Hubert de Guise, Luis L. Sanchez-Soto
We show here that the and V configurations of three-level atomic systems, while they have recently been shown to be equivalent for many important physical quantities when drive…
Interplay of topology and quantization: topological energy quantization in a cavity
Antonio F. Ranada
The interplay between quantization and topology is investigated in the frame of a topological model of electromagnetism proposed by the author. In that model, the energy of monochr…
