QuEnG Seminar - Operational thermodynamics from purity [CANCELLED]

on the May 16, 2019

At 2:00pm
As part of the QuEnG Seminar - Computer Science, we are pleased to welcome Carlos Mari Scandalo, from the University of Calgary who is researching operational thermodynamics in the framework of general probabilistic theories.
Abstract
In this talk we study the informational underpinnings of thermodynamics and statistical mechanics. To this purpose, we use an abstract framework—general probabilistic theories—, capable of describing arbitrary physical theories, which allows one to abstract the informational content of a theory from the concrete details of its formalism. In this framework, we extend the treatment of microcanonical thermodynamics, namely the thermodynamics of systems with a well-defined energy, beyond the known cases of classical and quantum theory. We formulate two requirements a theory should satisfy to have a well-defined microcanonical thermodynamics. We adopt the recent approach of resource theories, where one studies the transitions between states that can be accomplished with a restricted set of physical operations. We formulate three different resource theories, differing in the choice of the restricted set of physical operations. Specifically, we focus on a class of theories where every mixed state can be modelled as the reduced state of a pure entangled state. We show that in these theories it is possible to introduce well-behaved notions of majorisation and entropy.
