Witnessing pairing correlations in identical-particle systems Aksak, Cagan; Turgut, Sadi (2021-12-01) Quantum correlations and entanglement in identical-particle systems have been a puz-zling question which has attracted vast interest and widely different approaches. Witness formalism developed first for entanglement measu...
Entanglement-assisted state discrimination and entanglement preservation Gungor, Ozenc; Turgut, Sadi (2016-09-28) In this paper, the following scenario is considered: there are two qubits possessed by two parties at different locations. Qubits have been prepared in one of a maximum of four, mutually-orthogonal, entangled states and th...
An elementary derivation of the quantum virial theorem from Hellmann-Feynman theorem İpekoğlu, Yusuf; Turgut, Sadi (IOP Publishing, 2016-07-01) A simple proof of the quantum virial theorem that can be used in undergraduate courses is given. The proof proceeds by first showing that the energy eigenvalues of a Hamiltonian remain invariant under a scale transformatio...
Spin–orbit effects on the nonlinear optical properties of a quantum dot in simultaneous electric and magnetic fields Aytekin, O.; Turgut, Sadi; Tomak, Mehmet (Elsevier BV, 2014-11) We report on the nonlinear optical properties of a quantum dot including the Rashba spin-orbit interaction (RSOI) with external electric and magnetic fields. The effect of dot size is considered. We do not make any assumpt...
Nonlinear optical properties of a Woods-Saxon quantum dot under an electric field AYTEKİN, ÖZLEM; Turgut, Sadi; Unal, V. Ustoglu; Aksahin, E.; Tomak, Mehmet (Elsevier BV, 2013-12-01) A theoretical study of the effect of the confining potential on the nonlinear optical properties of two dimensional quantum dots is performed. A three-parameter Woods-Saxon potential is used within the density matrix forma...
A new sure-success generalization of Grover iteration and its application to weight decision problem of Boolean functions Uyanik, K.; Turgut, Sadi (Springer Science and Business Media LLC, 2013-11-01) In two recent papers, a sure-success version of the Grover iteration has been applied to solve the weight decision problem of a Boolean function and it is shown that it is quadratically faster than any classical algorithm ...
Nonlinear optical properties of a Poschl-Teller quantum well under electric and magnetic fields AYTEKİN, ÖZLEM; Turgut, Sadi; Tomak, Mehmet (2012-04-01) The nonlinear optical properties of a Poschl-Teller Quantum well (PTQW) under electric and magnetic fields are studied. The salient feature of this potential is its flexibility. It can be made asymmetrical by a proper choi...
Gauge covariance and spin-current conservation in the gauge-field formulation of systems with spin–orbit coupling Shikakhwa, M S; Turgut, Sadi; Pak, N K (IOP Publishing, 2012-2-23) The question of gauge covariance in the non-Abelian gauge-field formulation of two space-dimensional systems with spin-orbit coupling relevant to spintronics is investigated. Although these are generally gauge-fixed models...
Environmental effects on the geometric phase GÜNHAN, ALİ CAN; Turgut, Sadi; PAK, NAMIK KEMAL (2011-09-01) The behavior of the geometric phase gained by a single spin-1/2 nucleus immersed into a thermal or a squeezed environment is investigated. Both the time dependence of the phase and its value at infinity are examined agains...
A continuum model for dephasing in mesoscopic systems Şenozan, Selma; Turgut, Sadi; Tomak, Mehmet (Elsevier BV, 2011-08-01) A model of continuous dephasing for one-dimensional mesoscopic conductors is proposed. The model is based on Buttiker's fictitious-probe model which is extended by attaching an infinite number of probes uniformly to variou...
