Heat transport in low-dimensional systems
A Dhar - Advances in Physics, 2008 - Taylor & Francis
Recent results on theoretical studies of heat conduction in low-dimensional systems are
presented. These studies are on simple, yet non-trivial, models. Most of these are classical …

Nonlinear relativistic and quantum equations with a common type of solution
FD Nobre, MA Rego-Monteiro, C Tsallis - Physical review letters, 2011 - APS
Generalizations of the three main equations of quantum physics, namely, the Schrödinger,
Klein-Gordon, and Dirac equations, are proposed. Nonlinear terms, characterized by …

Non-linear waves in lattices: past, present, future
PG Kevrekidis - IMA Journal of Applied Mathematics, 2011 - academic.oup.com
In the present work, we attempt a brief summary of various areas where non-linear waves
have been emerging in the phenomenology of lattice dynamical systems. These areas …
