Quantum Phase Transitions in the Spin 1 Bilinear-Biquadratic Heisenberg Model Based on Classical and Quantum Correlations
Ghader Najarbashi, Hassan Bahmani, Babak Tarighi
We investigate thermal and nonthermal quantum correlations in the one dimensional spin 1 bilinear-biquadratic Heisenberg model. Using tools from quantum information theory such as…
Geometric phase for mixed squeezed-coherent states
Sanaz Mohammadi Almas, Ghader Najarbashi
In this paper, we investigate the geometric phase (GP) acquired by two-mode mixed squeezed-coherent states (SCSs) during unitary cyclic evolution, focusing on the influence of sque…
Geometric phase for two-mode entangled squeezed-coherent states
Sanaz Mohammadi Almas, Ghader Najarbashi, Ali Tavana
In this paper, we study the geometric phase (GP) of two-mode entangled squeezed-coherent states (ESCSs), undergoing a unitary cyclic evolution. It is revealed that by increasing th…
One-Mode Wigner Quasi-probability Distribution Function for Entangled Coherent States Generated by Beam Splitter and Cavity QED
G. Najarbashi, S. Mirzaei
In this paper, we use the displacement operator together with parity operation to construct the superposition of two coherent states. By transmitting this superposition from 50-50…
Comparison of Qubit and Qutrit like Entangled Squeezed and Coherent States of Light
G. Najarbashi, S. Mirzaei
Squeezed state of light is one of the important subjects in quantum optics which is generated by optical nonlinear interactions. In this paper, we especially focus on qubit like en…
Relation Between Stereographic Projection and Concurrence Measure in Bipartite Pure States
Ghader Najarbashi, Bahman Seifi
One-qubit pure states, living on the surface of Bloch sphere, can be mapped onto the usual complex plane by using stereographic projection. In this paper, after reviewing the entan…
