Spin squeezing in nonlinear spin-coherent states

Published Apr 12, 2001• 39 citations
arXivHTMLPDF

Abstract

We introduce the nonlinear spin-coherent state (SCS) via its ladder operator formalism and propose a type of nonlinear SCS by the nonlinear time evolution of the SCS. By a new version of spectroscopic squeezing criteria we study the spin squeezing in both the SCS and the nonlinear SCS. The results show that the SCS is not squeezed in the x , y and z directions, and the nonlinear SCS may be squeezed in the x and y directions.

Squeezing in the Real and Imaginary Spin Coherent States

Dong Yan, Xiaoguang Wang, Ling-An Wu

We study spin squeezing properties in the real and imaginary spin coherent states. We obtain analytical expressions of two spin squeezing parameters via a novel ladder operator formalism of the spin coherent state and the generation function method. Numerical results of the spin squeezing properties are discussed in detail, and the real and imaginary spin coherent state can be spin squeezed over a large range of parameters.

Spin squeezing and entanglement in superposition of nonlinear spin coherent states

Azita Naji, Mojtaba Jafarpour, Fatemeh Sammak

We study squeezing and entanglement in superposition of a class of nonlinear spin coherent states. We analyze these properties as a function of the coherence and superposition parameters, number of qubits and the Hamiltonians involved, by presenting analytical and numerical results. We specifically observe that a subclass of these states, the even non-linear cat states are maximally entangled and squeezed, while another related subclass, the odd non-linear cat states, are entangled but not squeezed at all.

Mean spin direction and spin squeezing in superpositions of spin coherent states

Dong Yan, Xiaoguang Wang, Lijun Song +1 more

Abstract We consider the mean spin direction (MSD) of superpositions of two spin coherent states (SCS) | ± μ〉, and superpositions of | μ〉 and | μ*〉 with a relative phase. We find that the azimuthal angle exhibits a π transition for both states when we vary the relative phase. The spin squeezing of the states, and the bosonic counterpart of the mean spin direction are also discussed.

Geometric phases of nonlinear coherent and squeezed states: a new approach

S.AL. Modares Vamegh, Mohammad Kazem Tavassoly

Recently, geometric phases of nonlinear coherent and squeezed states have been investigated by Yang et al (2011 J. Phys. B: At. Mol. Opt. Phys. 44 075502). In this paper, after a modification of Yang et al's derivation procedure, we deduced the non-cyclic and non-unitary geometric phases of nonlinear coherent and nonlinear squeezed states with a new approach which is consistent with the nonlinear coherent states theory. Indeed, the most important distinguishable feature of our presentation lies in the fact that we employed the (nonlinear) Hamiltonian which appropriately generates the time evolution of nonlinear coherent and squeezed states. It is established that this modification directly affects the resultant geometric phases of the states under consideration. As a physical realization, we applied our formalism to a particular nonlinear physical system corresponding to the centre-of-mass motion of a trapped ion coherent state. Then, the variation of the geometric phases of the considered nonlinear states in terms of time, intensity of radiation field, squeezing and Lamb–Dicke parameters are investigated. Finally, we discuss our numerical results.

Coherence and squeezing in Z3‐graded spin coherent states

Won Sang Chung

Abstract A new kind of spin coherent state called a Z3‐graded spin coherent state is constructed by using the complex solution of the equation q3 = 1. We explicitly find three kinds of Z3‐graded spin coherent states. The associated coherent property and spin squeezing are also examined.
