Non-Hermitian Quantum Mechanics with Minimal Length Uncertainty
T. K. Jana, P. Roy
We study non-Hermitian quantum mechanics in the presence of a minimal length. In particular we obtain exact solutions of a non-Hermitian displaced harmonic oscillator and the Swans…
Recurrence and ergodicity of random walks on linear groups and on homogeneous spaces
Y. Guivarc'h, C. R. E. Raja
We discuss recurrence and ergodicity properties of random walks and associated skew products for large classes of locally compact groups and homogeneous spaces. In particular we sh…
On the One Dimensional Critical "Learning from Neighbours" Model
Antar Bandyopadhyay, Rahul Roy, Anish Sarkar
We consider a model of a discrete time "interacting particle system" on the integer line where infinitely many changes are allowed at each instance of time. We describe the model u…
A study of frequency and size distribution dependence of extinction for astronomical silicate and graphite grains
Ashim K. Roy, Subodh K. Sharma, Ranjan Gupta
It is generally agreed that interstellar dust grains consist of two main components, namely, silicates and graphites. Some models, like MRN model, assume these grains to be homogen…
Fast Bayesian Semiparametric Curve-Fitting and Clustering in Massive Data With Application to Cosmology
Sabyasachi Mukhopadhyay, Sisir Roy, Sourabh Bhattacharya
Recent technological advances have led to a flood of new data on cosmology rich in information about the formation and evolution of the universe, e.g., the data collected in Sloan…
Solutions on 1D and 2D Density Classification Problem Using Programmable Cellular Automata
Sudhakar Sahoo, Pabitra Pal Choudhury, Amita Pal +1
This paper presents solutions to Density Classification Task (DCT) using a variant of Cellular Automata (CA) called Programmable Cellular Automata (PCA). The translation property a…
