Numerical relaxation of a 3D MHD Taylor - Woltjer state subject to abrupt expansion
Rupak Mukherjee, Rajaraman Ganesh
Since the advent of Taylor-Woltjer theory [J B Taylor, PRL, 33, 1139 (1974), L Woltjer, PNAS, 44, 489 (1958)], it has been widely believed that situations with perfectly conducting…
Recurrence in three dimensional magnetohydrodynamic plasma
Rupak Mukherjee, Rajaraman Ganesh, Abhijit Sen
We report on a numerical observation of recurrence phenomenon in a three dimensional magneto-hydrodynamic (MHD) plasma for certain classes of initial flow profiles. Our simulations…
Coherent nonlinear oscillations in magnetohydrodynamic plasma
Rupak Mukherjee, Rajaraman Ganesh, Abhijit Sen
Single fluid magnetohydrodynamic (MHD) equations have been studied through direct numerical simulations (DNS) using pseudo-spectral methods in two as well as three spatial dimensio…
Excitonic collective modes in Weyl semi-metals
N. S. Srivatsa, R. Ganesh
Weyl semi-metals are three dimensional generalizations of graphene with point-like Fermi surfaces. Their linear electronic dispersion leads to a window in the particle-hole excitat…
Experimental observation of drift wave turbulence in an inhomogeneous six-pole cusp magnetic field of MPD
A. D. Patel, M. Sharma, R. Ganesh +2
This paper presents a detailed study on the controlled experimental observation of drift wave instabilities in an inhomogeneous Six pole cusp magnetic field generated by an in-hous…
Tunable disorder and localization in the rare-earth nickelates
Changan Wang, Ching-Hao Chang, Angus Huang +13
The rare-earth nickelates are a rich playground for transport properties, known to host non-Fermi liquid character, resistance saturation and metal-insulator transitions. We report…
Vortex core ordering in Abrikosov lattices
Madhuparna Karmakar, R. Ganesh
Vortex lattices, arising from repulsive inter-vortex interactions, are a canonical example of emergent phenomena. Recent studies on the cuprates have drawn attention to the appeara…
Resonating valence bonds and spinon pairing in the Dicke model
R. Ganesh, L. Theerthagiri, G. Baskaran
Resonating valence bond (RVB) states are a class of entangled quantum many body wavefunctions with great significance in condensed matter physics. We propose a scheme to synthesize…
Dirac cones and mass terms in bosonic spectra
P. Sathish Kumar, R. Ganesh
The notion of Dirac cones, wherein two or more bands become degenerate at a certain momentum, is the starting point for the study of topological phases. Dirac cones have been thoro…
Carrier driven antiferromagnetism and exchange-bias in SrRuO3/CaRuO3 heterostructures
Parul Pandey, Ching-Hao Chang, Angus Huang +7
Oxide heterostructures exhibit a rich variety of magnetic and transport properties which arise due to contact at an interface. This can lead to surprising effects that are very dif…
Compressibility effects on quasistationary vortex and transient hole patterns through vortex merger
Rupak Mukherjee, Akanksha Gupta, Rajaraman Ganesh
The effect of compressibility in hydrodynamic vortex merging has been discussed. In the past, in incompressible limit it has been observed that the merging of a collection of inten…
