Are rare rogue fluctuations generic to strongly nonlinear and non-integrable systems?

Rahul Kashyap, Surajit Sen

Extensive dynamical simulations are used to explore the possible existence of sudden sufficiently large energy or rogue fluctuations (RF) at late times and across short time window…

Quasi-stable Localized Excitations in the β-Fermi Pasta Ulam Tsingou System

Nathaniel J. Fuller, Surajit Sen

The lifetimes of localized nonlinear modes in both the -Fermi-Pasta-Ulam-Tsingou (-FPUT) chain and a cubic -FPUT lattice are studied as functions of perturbation amplitude…

A Compendium on General Relativity for Undergraduate Students

Tushar Kanti Dey, Surajit Sen

We give a pedagogical introduction of the essential features of General Theory of Relativity (GTR) in the format of an undergraduate (UG) project. A set of simple MATHEMATICA code…

On the generation and propagation of solitary waves in integrable and non-integrable nonlinear lattices

Guo Deng, Gino Biondini, Surajit Sen +1

We investigate the generation and propagation of solitary waves in the context of the Hertz chain and Toda lattice, with the aim to highlight the similarities, as well as differenc…

Entangled States of Qutrit Bipartite System

Surajit Sen, Tushar Kanti Dey

We develop a systematic method to construct the Bell states of a qubit bipartite system while taking group as the basis group. An alternative formulation of fidelity, calle…

Nonlinear normal modes in the -Fermi-Pasta-Ulam-Tsingou chain

Nathaniel J. Fuller, Surajit Sen

Nonlinear normal mode solutions of the -FPUT chain with fixed boundaries are presented in terms of the Jacobi sn function. Exact solutions for the two particle chain are found f…
