A note on some perfect fluid Kantowski-Sachs and Bianchi type III space-times and their conformal vector fields in f(R) theory of gravity
Ghulam Shabbir, Fiaz Hussain, A. H. Kara +1
The purpose of this paper is to find conformal vector fields of some perfect fluid Kantowski-Sachs and Bianchi type III space-times in the f(R) theory of gravity using direct integ…
Decoherence effects on multiplayer cooperative quantum games
Salman Khan, M. Ramzan, M. Khalid Khan
We study the behavior of cooperative multiplayer quantum games [35,36] in the presence of decoherence using different quantum channels such as amplitude damping, depolarizing and p…
Proper curvature collineations in non-static plane symmetric space-times
Ghulam Shabbir, M. Ramzan
The most general form of non-static plane symmetric space-times is considered to study proper curvature collineations by using the rank of the 6X6 Riemann matrix and direct integra…

Dynamics of multipartite quantum correlations under decoherence
M. Ramzan
Quantum discord is an optimal resource for the quantification of classical and non-classical correlations as compared to other related measures. Geometric measure of quantum discor…
Environmental influences on Quantum Monty Hall problem
Salman Khan, M. Ramzan, M. K. Khan
We reformulate the quantum Monty Hall problem in the presence of decoherence. The decoherence destroys the fairness of the game. A new Nash equilibrium for a particular strategy pr…
Quantum Model of Bertrand Duopoly
Salman Khan, M. Ramzan, M. K. Khan
We present the quantum model of Bertrand duopoly and study the entanglement behavior on the profit functions of the firms. Using the concept of optimal response of each firm to the…
Quantum Parrondo's games under decoherence
Salman Khan, M. Ramzan, M. K. Khan
We study the effect of quantum noise on history dependent quantum Parrondo's games by taking into account different noise channels. Our calculations show that entanglement can play…
Quantum Monty Hall problem under decoherence
Salman Khan, M. Ramzan, M. K. Khan
We study the effect of decoherence on quantum Monty Hall problem under the influence of amplitude damping, depolarizing and dephasing channels. It is shown that under the effect of…
