Boson-fermion unification, superstrings, and Bohmian mechanics

TL;DR

This paper unifies bosonic and fermionic currents via superstring theory, introduces a preferred foliation at the effective field level, and supports a covariant Bohmian interpretation of quantum mechanics and superstrings.

Contribution

It demonstrates that a unified treatment of bosons and fermions arises naturally from superstring currents, with a consistent Bohmian interpretation that remains relativistically covariant.

Findings

Unified boson-fermion currents from superstring theory

Objective particle definition in curved spacetime

Bohmian interpretation of superstrings with covariant equations

Abstract

Bosonic and fermionic particle currents can be introduced in a more unified way, with the cost of introducing a preferred spacetime foliation. Such a unified treatment of bosons and fermions naturally emerges from an analogous superstring current, showing that the preferred spacetime foliation appears only at the level of effective field theory, not at the fundamental superstring level. The existence of the preferred spacetime foliation allows an objective definition of particles associated with quantum field theory in curved spacetime. Such an objective definition of particles makes the Bohmian interpretation of particle quantum mechanics more appealing. The superstring current allows a consistent Bohmian interpretation of superstrings themselves, including a Bohmian description of string creation and destruction in terms of string splitting. The Bohmian equations of motion and the corresponding probabilistic predictions are fully relativistic covariant and do not depend on the preferred foliation.
