Emergence of a Macroscopic Cat State and Multi-Channel Entanglement in a Frustrated Cluster Spin Chain

Mohit Lal Bera, Andreu Anglés-Castillo, Alberto Acevedo Meléndez +8

The paper investigates a one‑dimensional frustrated spin chain that combines cluster‑Ising and anisotropic next‑nearest‑neighbor Ising interactions, revealing two distinct quantum…

Adaptive time Compressed QITE (ACQ) and its geometrical interpretation

Alberto Acevedo Meléndez, Carmen G. Almudéver, Miguel Angel Garcia-March +8

Imaginary time evolution (ITE) is a well-established method for ground-state preparation, a fundamental problem in many fields such as materials science, chemistry, and optimizatio…

Entanglement Transfer Dynamics in a Two-Leg Spin Ladder Under a Selective Magnetic Field

Soghra Ghanavat, Abbas Sabour, Somayeh Mehrabankar

We investigate the dynamical transfer of bipartite entanglement through a two-leg spin-1/2 ladder governed by the anisotropic Heisenberg (XXZ-type) model with a selective magnetic…

Dynamical Evolution of Quantum Correlations and Decoherence in Coupled Oscillators Interacting with a Thermal Reservoir

Somayeh Mehrabankar, Farkhondeh Abbasnezhad, Davood Afshar +1

We investigate the dynamical evolution of quantum discord, entanglement and purity in an open quantum system of two coupled asymmetric harmonic oscillators interacting with a therm…
