Unitarity of the time-evolution and observability of non-Hermitian Hamiltonians for time-dependent Dyson maps
F. S. Luiz, M. A. Pontes, M. H. Y. Moussa
Here we present an strategy for the derivation of a time-dependent Dyson map which ensures simultaneously the unitarity of the time evolution and the observability of a quasi-Hermi…
Spin coherent states in NMR quadrupolar system: experimental and theoretical applications
R. Auccaise, E. R. deAzevedo, E. I. Duzzioni +2
Working with nuclear magnetic resonance (NMR) in quadrupolar spin systems, in this paper we transfer the concept of atomic coherent state to the nuclear spin context, where it is r…
Quasi-perfect state transfer in a bosonic dissipative network
A. Cacheffo, M. A. de Ponte, M. H. Y. Moussa +1
In this paper we propose a scheme for quasi-perfect state transfer in a network of dissipative harmonic oscillators. We consider ideal sender and receiver oscillators connected by…
Temperature effects on a network of dissipative quantum harmonic oscillators: collective damping and diffusion processes
M. A. de Ponte, S. S. Mizrahi, M. H. Y. Moussa
In this article we extend the results presented in Ref. [Phys. Rev. A 76, 032101 (2007)] to treat quantitatively the effects of reservoirs at finite temperature in a bosonic dissip…
Storing quantum states in bosonic dissipative networks
M. A. de Ponte, S. S. Mizrahi, M. H. Y. Moussa
Considering a network of dissipative quantum harmonic oscillators we deduce and analyze the optimum topologies which are able to store, for the largest period of time, a quantum su…
Decoherence in strongly coupled quantum oscillators
M. A. de Ponte, M. C. de Oliveira, M. H. Y. Moussa
In this paper we present a comprehensive analysis of the coherence phenomenon of two coupled dissipative oscillators. The action of a classical driving field on one of the oscillat…
