Wave function for the squeezed atomic coherent state in entangled state representation and some of its applications
TL;DR: In this article, the wave function for the squeezed atomic coherent state (SACS) was introduced, which turns out to be just proportional to a single-variable ordinary Hermite polynomial of order 2j.
Journal ArticleDOI
Two-mode bosonic squeezing and symmetry breaking
TL;DR: In this paper, the authors defined the concept of squeezed boson systems and applied the Hamiltonian H = γ S z 2 − B S x to investigate the ground-state energy of two-mode boson system.

Supersymmetric analysis of a spin Hamiltonian model
TL;DR: In this article, the intertwining method has been applied to the effective potential of the spin Hamiltonian H = − γ S z 2 − B S x, where supersymmetric partner potentials are obtained by using low-lying states of this potential.

The Hierarchy problem and new dimensions at a millimeter
TL;DR: In this paper, the authors propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor, and they take as the only fundamental short distance scale in nature.

Squeezed spin states
Masahiro Kitagawa,Masahito Ueda +1 more
TL;DR: Two proposed mechanisms, referred to as one-axis twisting and two-axis countertwisting, are shown to reduce the standard quantum noise S/2 of the coherent S-spin state down to 1/2(S/3${)}^{1/3}$ and 1/3, respectively.

Coherent states for arbitrary Lie group
TL;DR: In this paper, the concept of coherent states originally closely related to the nilpotent group of Weyl is generalized to arbitrary Lie groups and its features are investigated for the simplest Lie groups.

'Nonclassical' states in quantum optics: a 'squeezed' review of the first 75 years
TL;DR: A review of studies performed in the field of non-classical states can be found in this article, with a focus on the evolution of Gaussian wave packets for an oscillator, a free particle and a particle moving in uniform constant electric and magnetic fields.
