Against Fields

...the concept of fields as mediators of particle interactions turns out to be philosophically unsatisfying and physically problematic, as it leads, in particular, to problematic self-interactions. Against this background, I will argue that the true significance of fields is that of “book-keeping variables”...

Indistinguishability

The concept of particle indistinguishability thus construed faces some obvious challenges. It remains controversial, now for more than a century, whether classical particles can be treated as indistinguishable; or if they can, whether the puzzles raised by Gibbs are thereby solved or alleviated; and if so, how the differences between quantum and classical statistics are to be explained.

Radiation from a Uniformly Accelerated Charge and the Equivalence Principle

It is generally accepted that any accelerated charge in Minkowski space radiates energy. It is also accepted that a stationary charge in a static gravitational field (such as a Schwarzschild field) does not radiate energy. It would seem that these two facts imply that some forms of Einstein’s Equivalence Principle do not apply to charged particles.

On the Exact Identity Between Thermodynamic and Informatic Entropies in a Unitary Model of Friction (Diósi Lajos?)

We consider an elementary collision model of a molecular reservoir upon which an external field is applied and the work is dissipated into heat. To realize macroscopic irreversibility at the microscopic level, we introduce a “graceful” irreversible map which randomly mixes the identities of the molecules. This map is expected to generate informatic entropy exactly equal to the independently calculable irreversible thermodynamic entropy.
