2-Day Workshop “Celebrating the 60th anniversary of Sudarshan’s paper on dynamical maps”

Ennackal Chandy George Sudarshan
(1931 – 2018)

P.M. Mathews


Jayaseetha Rau


The most general dynamical equation of an open quantum system was addressed in a remarkable paper (Phys. Rev.121, 920 (1961)) by Sudarshan, Mathews, and Rau (SMR) entitled “Stochastic Dynamics of Quantum Mechanical Systems”.

The paper introduced the notion of a dynamical matrix, associated with any quantum map. Positivity of this Hermitian matrix implies that the corresponding map is completely positive. However, the paper did not receive enough attention from the community, as the notion of complete positivity was not yet introduced.

The workshop, organised by NitheCS and the Institute of Theoretical Physics, Jagiellonian University (IFT UJ), aims to celebrate the 60th anniversary of this fundamental paper and is devoted to new frontiers in the research in open quantum systems and entanglement.
