Quantum phase transitions without thermodynamic limits
Dorje C. Brody, Daniel W. Hook, Lane P. Hughston
A new microcanonical equilibrium state is introduced for quantum systems with finite-dimensional state spaces. Equilibrium is characterised by a uniform distribution on a level sur…

Microcanonical distributions for quantum systems
Dorje C Brody, Daniel W Hook, Lane P Hughston
The standard assumption for the equilibrium microcanonical state in quantum mechanics, that the system must be in one of the energy eigenstates, is weakened so as to allow superpos…
