A characterization of orthogonal permutative matrices of order 4
Amrita Mandal, Bibhas Adhikari
Orthogonal matrices which are linear combinations of permutation matrices have attracted enormous attention in quantum information and computation. In this paper, we provide a comp…
Limit theorems and localization of three state quantum walks on a line defined by generalized Grover coins
Amrita Mandal, Rohit Sarma Sarkar, Shantanav Chakraborty +1
In this article, we undertake a detailed study of the limiting behavior of a three-state discrete-time quantum walk on one dimensional lattice with generalized Grover coins. Two li…
Localization of two-dimensional quantum walks defined by generalized Grover coins
Amrita Mandal, Rohit Sarma Sarkar, Bibhas Adhikari
Localization phenomena of quantum walks makes the propagation dynamics of a walker strikingly different from that corresponding to classical random walks. In this paper, we study t…
Periodicity of lively quantum walks on cycles with generalized Grover coin
Rohit Sarma Sarkar, Amrita Mandal, Bibhas Adhikari
In this paper we extend the study of three state lively quantum walks on cycles by considering the coin operator as a linear sum of permutation matrices, which is a generalization…
Magnetodielectric effect in nickel nanosheet-Na-4 mica composites
Sreemanta Mitra, Amrita Mandal, Anindya Datta +2
Nickel nanosheets of thickness 0.6 nm were grown within the nanochannels of Na-4 mica template. The specimens show magnetodielectric effect at room temperature with a change of die…
Ferromagnetic behavior of ultrathin manganese nanosheets
Sreemanta Mitra, Amrita Mandal, Anindya Datta +2
Ferromagnetic behaviour has been observed experimentally for the first time in nanostructured Manganese. Ultrathin ( 0.6 nm) Manganese nanosheets have been synthesized inside…
Enhanced magnetic anisotropy of Nickel nanosheet prepared in Na-4 mica
Sreemanta Mitra, Amrita Mandal, Anindya Datta +2
Nanosheets of nickel with thickness equal to 0.6 nm have been grown within the interlayer spaces of Na-4 mica. The sheets are made up of percolative clusters of nanodisks. Magnetiz…
