Negative heat capacities in spherically symmetric sectors of $d$ -matrix quantum mechanics

Denjoe O'Connor, Sanjaye Ramgoolam

We consider the $S O (d)$ and $O (d)$ invariant sectors of the bosonic $d$ -matrix harmonic oscillator with $U (N)$ gauge symmetry. The micro-canonical degeneracy $\mathcal{Z}( N , d ,…

Gauged permutation invariant tensor quantum mechanics, least common multiples and the inclusion-exclusion principle

Denjoe O'Connor, Sanjaye Ramgoolam

We derive the canonical ensemble partition functions for gauged permutation invariant tensor quantum harmonic oscillator thermodynamics, finding surprisingly simple expressions wit…

Permutation invariant matrix quantum thermodynamics and negative specific heat capacities in large N systems

Denjoe O'Connor, Sanjaye Ramgoolam

We study the thermodynamic properties of the simplest gauged permutation invariant matrix quantum mechanical system of oscillators, for general matrix size $N$ . In the canonical en…
