Tunneling effects in a one-dimensional quantum walk
Mostafa Annabestani, Seyed Javad Akhtarshenas, Mohamad Reza Abolhassani
In this article we investigate the effects of shifting position decoherence, arisen from the tunneling effect in the experimental realization of the quantum walk, on the one-dimens…
Spherical Symmetric Solution in f(R) Model Around Charged Black Hole
A. Aghamohammadi, Kh. Saaidi, M. R. Abolhasani +1
A static, asymptotically flat, spherically symmetric solutions is investigated in f(R) theories of gravity for a charged black hole. We have studied the weak field limit of f(R) gr…
Standard Cosmological Evolution in f(R) Model to Kaluza Klein Cosmology
A. Aghmohammadi, Kh. Saaidi, M. R. Abolhassani +1
In this paper, using theory of gravity we explicitly calculate cosmological evolution in the presence of a perfect fluid source in four and five dimensional, space time in w…
Decoherence in one-dimensional Quantum Walk
Mostafa Annabestani, Seyed Javad Akhtarshenas, Mohamad Reza Abolhassani
In this paper we study decoherence in the quantum walk on the line. We generalize the method of decoherent coin quantum walk, introduced by Brun et al [Phys. Rev. A {\bf 67}, 32304…
