Experimental Evidence of Directivity-Enhancing Mechanisms in Nonlinear Lattices
R. Ganesh, Stefano Gonella
In this letter, we experimentally investigate the directional characteristics of propagating, finite-amplitude wave packets in lattice materials, with an emphasis on the functional…
Impurity induced current in a Chern insulator
Vibhuti Bhushan Jha, Garima Rani, R. Ganesh
Chern insulators arguably provide the simplest examples of topological phases. They are characterized by a topological invariant and can be identified by the presence of protected…
Generating resonating valence bond states through Dicke subradiance
R. Ganesh, L. Theerthagiri, G. Baskaran
Dicke's original thought experiment with two spins coupled to a photon mode has recently been experimentally realized. We propose extending this experiment to N spins and show that…
Nonlinear Waves in Lattice Materials: Adaptively Augmented Directivity and Functionality Enhancement by Modal Mixing
R. Ganesh, Stefano Gonella
The motive of this work is to understand the complex spatial characteristics of finite-amplitude elastic wave propagation in periodic structures and leverage the unique opportuniti…
Influence of electron-neutral elastic collisions on the instability of an ion-contaminated cylindrical electron cloud: 2D3V PIC-with-MCC simulations
Meghraj Sengupta, Rajaraman Ganesh
This paper is a simulation based investigation of the effect of elastic collisions and effectively elastic-like excitation collisions between electrons and background neutrals on t…
Molecular shear heating and vortex dynamics in thermostatted two-dimensional Yukawa liquids
Akanksha Gupta, Rajaraman Ganesh, Ashwin Joy
It is well known that two-dimensional macroscale shear flows are susceptible to instabilities leading to macroscale vortical structures. The linear and nonlinear fate of such a mac…
Extended degeneracy and order by disorder in the square lattice J-J-J model
Bimla Danu, Gautam Nambiar, R. Ganesh
The square lattice antiferromagnet with frustrating next nearest neighbour coupling continues to generate tremendous interest, with an elusive quantum disordered phase in the vicin…
