I give some personal reflections on Jacob Bekenstein’s pioneering work on associating an entropy with a black hole proportional to its area and on the generalized second law of thermodynamics.

A brief review of “Holographic Space-Time” in the light of the seminal contributions of Jacob Bekenstein.

In 1974 Jacob Bekenstein has noticed that the area of the black hole behaves as adiabatic invariant and hence most likely must be quantized in integers of the Planckian area. In these notes I will present the arguments which led him and myself to such a conclusion and will discuss the consequences of the black hole quantization.

The objective of this book is to get the reader acquainted with theoretical and mathematical foundations of the concept of Wilson loops in the context of modern quantum field theory. It teaches how to perform independently some elementary calculations on Wilson lines, and shows the recent development of the subject in different important areas of r...

We outline our proposal for a field theory description of steady state incompressible fluid turbulence at the inertial range of scales in a general number of space dimensions. The theory consists of a Kolmogorov linear scaling mean field theory dressed by a Nambu–Goldstone dilaton mode that induces a random measure on the inertial range. We derive ...

We argue that four-dimensional black hole evaporation inevitably produces an infinite number of soft particles in addition to the thermally distributed ‘hard’ Hawking quanta, and moreover that the soft and hard particles are highly correlated. This raises the possibility that quantum purity is restored by correlations between the hard and soft radi...

We summarize our recent work on the foundational aspects of string theory as a quantum theory of gravity. We emphasize the hidden quantum geometry (modular spacetime) behind the generic representation of quantum theory and then stress that the same geometric structure underlies a manifestly T-duality covariant formulation of string theory, that we ...

We consider the possibility that the preons defined by the SLq(2) extension of the Standard Model may be identified with Schwinger dyons. The SLq(2) extension is here presented as a model that may exist in either a currently observable electric phase or in a magnetic phase that is predicted but currently unobservable.

Motivated by the ideas of Jacob Bekenstein concerning gravity-assisted symmetry breaking, we consider a non-canonical model of f(R) = R + R2 extended gravity coupled to neutral scalar “inflaton”, as well as to SU(2) × U(1) multiplet of fields matching the content of the bosonic sector of the electroweak particle model, however with the following si...
