A bstract We first present an analysis of infinitesimal null deformations for the entanglement entropy, which leads to a major simplification proof C , F and -theorems in quantum field theory. Next, we study energy condition (QNEC) on light-cone CFT. Finally, combine these tools order establish irreversibility renormalization group flows planar d -dimensional defects, embedded D conformal theor...

We present an overview of recent work together with J. Hoffman, A. Logg and R. Scott developing a new approach towards resolving the classical paradox of irreversibility in formally reversible Hamiltonian systems such as inviscid fluid models and particle models. We base our solution on finite precision computation in the form of General Galerkin G2, instead of statistical mechanics, which is t...

The interaction between concepts of irreversibility and the development of non-equilibrium statistical mechanics is discussed with particular reference to certain 'paradoxes' that retarded this development A recently evolved attitude towards the general problem of irreversibility may be considered responsible for a number of practical advances in this field. My subject is the interaction betwee...

What is the physical significance of entropy? What is the physical origin of irreversibility? Do entropy and irreversibility exist only for complex and macroscopic systems? For everyday laboratory physics, the mathematical formalism of Statistical Mechanics (canonical and grand-canonical, Boltzmann, Bose-Einstein and Fermi-Dirac distributions) allows a successful description of the thermodynami...

A critical feature in the sequence of events occurring during carcinogenesis is the development of irreversibility. The term "Interlocker" is used here to denote a mechanism by which irreversibility is brought about. The presentation focuses on conceptualizations of such processes. Two will be described below.
