Negative temperature-Examples-Noninteracting two-level particles The simplest example, albeit a rather nonphysical one, is to consider a system of N particles, each of which can take an energy of either +ε or −ε but are otherwise noninteracting. This can be understood as a limit of the Ising model in which the interact...

Negative temperature-Examples-By the fundamental assumption of statistical mechanics, the entropy of this microcanonical ensemble is ln ⁡ΩE We can solve for thermodynamic beta (β = 1/kBT) by considering it as a central difference without taking the continuum limit: ln ln ln ln ⁡(N−j+1N+j+1). hence the temperature ln ⁡(...

Negative temperature-Examples-This entire proof assumes the microcanonical ensemble with energy fixed and temperature being the emergent property. In the canonical ensemble, the temperature is fixed and energy is the emergent property. This leads to (ε refers to microstates): ln ⁡(Z)+ET Following the previous example, ...
