Quantum phase transitions in the spin-1 bilinear-biquadratic Heisenberg model based on classical and quantum correlations

G. Najarbashi, Babak Tarighi

We investigate thermal and non-thermal quantum correlations in the one-dimensional spin-1 bilinear-biquadratic Heisenberg model. Using tools from quantum information theory-such as generalized concurrence, negativity, and various measures of quantum, classical, and total correlations in bipartite states-we demonstrate that these measures effectively identify …

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 generalized concurrence, negativity, and various measures of quantum, classical, and total correlations in bipartite states we demonstrate that …

Geometric phase for mixed squeezed-coherent states

S. Mohammadi Almas, G. Najarbashi

In this paper, we investigate the geometric phase (GP) acquired by two-mode mixed squeezed-coherent states (SCSs) during unitary cyclic evolution, examining the influence of squeezing parameter and classical weight. We analyze the GP for three distinct mixed states, each characterized by different …

Geometric phase for two-mode entangled squeezed-coherent states

S. Mohammadi Almas, G. Najarbashi, A. Tavana

In this paper, we investigate the geometric phase (GP) of two-mode entangled squeezed-coherent states (ESCSs), undergoing unitary cyclic evolution. Results show that increasing the squeezing parameter of either mode of the balanced ESCS compresses the GP elliptically with respect to the coherence …

Geometric phase for two-mode entangled squeezed-coherent states

Sanaz Mohammadi Almas, G. Najarbashi, Ali Mehrabi 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 the squeezing parameter of the first or the second mode of a balanced ESCS, the GP …

Generalized concurrence and quantum phase transition in spin-1 Heisenberg model

Hassan Bahmani, G. Najarbashi, A. Tavana

Abstract In this paper we investigate the ability of the generalized concurrence as a quantum entanglement measure to describe the quantum and thermal phase transitions in the spin-1 Heisenberg model with bilinear and biquadratic interactions and single-ion anisotropy terms, under a magnetic …
