Eleven-dimensional Lorentz symmetry from SUSY quantum mechanics

Eleven-Dimensional Lorentz Symmetry from SUSY Quantum Mechanics

The supermembrane in light-cone gauge gives rise to a supersymmetric quantum mechanics system with SU(N) gauge symmetry when the group of area preserving diffeomorphisms is suitably regulated. de Wit, Marquard and Nicolai showed how eleven-dimensional Lorentz generators can be constructed from these degrees of freedom at the classical level. In this paper, these considerations are extended to t...

Quantum Measurement Breaks Lorentz Symmetry

Traditionally causes come before effects, but according to modern physics things aren't that simple. Special relativity shows that 'before' and 'after' are relative , and quantum measurement is even more subtle. Since the nonlocality of Bell's theorem, it has been known that quantum measurement has an uneasy relation with special relativity, described by Shimony as 'peaceful coexistence'. Hardy...

Quantum Mechanics from Focusing and Symmetry

A foundation of quantum mechanics based on the concepts of focusing and symmetry is proposed. Focusing is connected to c-variables inaccessible conceptually derived variables; several examples of such variables are given. The focus is then on a maximal accessible parameter, a function of the common c-variable. Symmetry is introduced via a group acting on the c-variable. From this, the Hilbert s...
