Continuous Time Random Walk with time-dependent jump probability : A Direct Probabilistic Approach
Shovan Dutta, Subhankar Ray, J. Shamanna
We investigate the dynamics of a particle executing a general Continuous Time Random Walk (CTRW) in three dimensions under the influence of arbitrary time-varying external fields.…
Supersymmetric isospectral formalism for the calculation of near-zero energy states: application to the very weakly bound He trimer excited state
Sudip Kumar Haldar, Barnali Chakrabarti, Tapan Kumar Das
We propose a novel mathematical approach for the calculation of near-zero energy states by solving potentials which are isospectral with the original one. For any potential, famili…
Spectral fluctuation and noise in the energy level statistics of interacting trapped bosons
Kamalika Roy, Barnali Chakrabarti, Anindya Biswas +2
It has been recently shown numerically that the transition from integrability to chaos in quantum systems and the corresponding spectral fluctuations are characterized by $\frac{1}…
Linear Nearest Neighbor Synthesis of Reversible Circuits by Graph Partitioning
Amlan Chakrabarti, Susmita Sur-Kolay, Ayan Chaudhury
Linear Nearest Neighbor (LNN) synthesis in reversible circuits has emerged as an important issue in terms of technological implementation for quantum computation. The objective is…
Scattering states of a particle, with position-dependent mass, in a double heterojunction
Anjana Sinha
In this work we obtain the exact analytical scattering solutions of a particle (electron or hole) in a semiconductor double heterojunction - potential well / barrier - where the ef…
Steganography and Steganalysis: Different Approaches
Soumyendu Das, Subhendu Das, Bijoy Bandyopadhyay +1
Steganography is the technique of hiding confidential information within any media. Steganography is often confused with cryptography because the two are similar in the way that th…
