I am a theoretical physicist working in the areas of nonlinear dynamics and statistical physics at the Department of Theoretical Physics, Tata Institute of Fundamental Research, Mumbai, India.
I work on a wide variety of problems in nonlinear dynamics and statistical physics, including stochastic processes, stochastic thermodynamics, equilibrium and non-equilibrium dynamics of long-range interacting systems, synchronization, and quantum dynamics.
I serve on the Editorial Board of the IOP journal Journal of Physics A; Mathematical and Theoretical.
Currently, I do not have any postdoc openings in my group.
Facets of noise: Effects in classical and quantum systems
Debraj Das and Shamik Gupta
This book provides a captivating journey through the realms of classical and quantum systems as it unravels the profound influence that noise may have on their static and dynamic properties. The first part of the book offers succinct yet enlightening discussions on foundational topics related to noise. The second part focuses on a variety of applications, where a diverse spectrum of noise effects in physical systems comes to life, meticulously presented and thoughtfully analyzed. Whether you are a curious student or a dedicated researcher, this book is your key to gaining invaluable insights into noise effects in physical systems.
“The book has the merit of presenting several topics scattered in the literature and could become a very useful reference.” Giovanni Jona-Lasinio, Sapienza – Università di Roma, Italy
Statistical Physics of Synchronization
Shamik Gupta, Alessandro Campa, Stefano Ruffo
This book introduces and discusses the analysis of interacting many-body complex systems exhibiting spontaneous synchronization from the perspective of nonequilibrium statistical physics. While such systems have been mostly studied using dynamical system theory, the book underlines the usefulness of the statistical physics approach to obtain insightful results in a number of representative dynamical settings.
“This is a very valuable addition to the literature of dynamical systems and nonequilibrium statistical physics.” Steven Strogatz, Cornell University, USA
