Quantum Correlations in a Few-Atom Spin-1 Bose-Hubbard Model
B. Çakmak, G. Karpat, Z. Gedik
We study the thermal quantum correlations and entanglement in spin-1 Bose-Hubbard model with two and three particles. While we use negativity to calculate entanglement, more genera…
Invariant Quantum Discord in Qubit-Qutrit Systems under Local Dephasing
G. Karpat, Z. Gedik
We investigate the dynamics of quantum discord and entanglement for a class of mixed qubit-qutrit states assuming that only the qutrit is under the action of a dephasing channel. W…
Critical Point Estimation and Long-Range Behavior in the One-Dimensional XY Model Using Thermal Quantum and Total Correlations
B. Çakmak, G. Karpat, Z. Gedik
We investigate the thermal quantum and total correlations in the anisotropic XY spin chain in transverse field. While we adopt concurrence and geometric quantum discord to measure…
Eigenvalue Formulation of Quantum Mechanics Near Closed Timelike Curves
Z. Gedik
Einstein's field equations of gravitation are known to admit closed timelike curve (CTC) solutions. Deutsch approached the problem from the quantum information point of view and pr…
