In this paper, we investigate the entanglement of a quantum system containing two
subsystems characterized by the angular momenta j 1 and j 2, in the framework of the …

We investigate the entanglement of a bipartite partly non-orthogonal state of the form
$|\phi\rangle= u|\xi\rangle_1\otimes| 1\rangle_2+ v|\xi\rangle_1\otimes| 0\rangle_2+ …

Multimode macroscopic states consisting of a superposition of spin coherent states that are
generated in a trapped ion system are introduced. The role of various parameters that …

A detailed study of entanglement in three-spin superposition of SU (2) coherent states is
presented. Explicit expressions to quantify the entanglement of three-spin states for both W …

We introduce generalized multi-mode superposition of multi-dimensional coherent field
states and propose a generation scheme of such states in a cavity QED scenario. An …

A detailed investigation of entanglement in the generalized two-dimensional nonorthogonal
states, which are expressed in the framework of superposed coherent states, is presented. In …

In this paper, the geometric phase (GP) of a superposition state of two bipartite pure states is
formulated. Specially, we have focused on the GP of superposition states with two-bipartite …

In this paper, q-deformed oscillator for pseudo-Hermitian systems is investigated and
pseudo-Hermitian appropriate coherent and squeezed states are studied. Also, some basic …

In this paper, we introduce a controllable method for producing two and three-mode
entangled coherent states (ECS's) using atom-field interaction in cavity QED and beam …

We motivate and introduce a class of “hierarchical” quantum superposition states of N
coupled quantum oscillators. Unlike other well-known multimode photonic Schrödinger-cat …
