Anomalous heat transport in one dimensional systems: a description using non-local fractional-type diffusion equation
Abhishek Dhar, Anupam Kundu, Aritra Kundu
It has been observed in many numerical simulations, experiments and from various theoretical treatments that heat transport in one-dimensional systems of interacting particles cann…
Transport, correlations, and chaos in a classical disordered anharmonic chain
Manoj Kumar, Anupam Kundu, Manas Kulkarni +2
We explore transport properties in a disordered nonlinear chain of classical harmonic oscillators and thereby identify a regime exhibiting behavior analogous to that seen in quantu…
Thermalization of local observables in the -FPUT chain
Santhosh Ganapa, Amit Apte, Abhishek Dhar
Most studies on the problem of equilibration of the Fermi-Pasta-Ulam-Tsingou (FPUT) system have focused on equipartition of energy being attained amongst the normal modes of the co…
Fourier's law based on microscopic dynamics
Abhishek Dhar, Herbert Spohn
While Fourier's law is empirically confirmed for many substances and over an extremely wide range of thermodynamic parameters, a convincing microscopic derivation still poses diffi…
Kardar-Parisi-Zhang Scaling for an Integrable Lattice Landau-Lifshitz Spin Chain
Avijit Das, Manas Kulkarni, Herbert Spohn +1
Recent studies report on anomalous spin transport for the integrable Heisenberg spin chain at its isotropic point. Anomalous scaling is also observed in the time-evolution of non-e…
Some connections between the Classical Calogero-Moser model and the Log Gas
Sanaa Agarwal, Manas Kulkarni, Abhishek Dhar
In this work we discuss connections between a one-dimensional system of particles interacting with a repulsive inverse square potential and confined in a harmonic potential (Ca…
