We elucidate how Quantum Thermodynamics at temperature T emerges from pure and classical SU(2)

SU(2) Yang–Mills theory on a four-dimensional Euclidean spacetime slice S1×R3.The concept of a (deconfining) thermal ground state, composed of certain solutions to the fundamental, classical Yang–Mills equation, allows for a unified addressation of both (classical) wave- and (quantum) particle-like excitations thereof. More definitely, the thermal ground state represents the interplay between nonpropagating, periodic configurations which are electric-magnetically (anti)selfdual in a non-trivial way and possess topological charge modulus unity. Their trivial-holonomy versions—Harrington–Shepard (HS) (anti)calorons—yield an accurate a priori estimate of the thermal ground state in terms of spatially coarse-grained centers, each containing one quantum of action ℏ localized at its inmost spacetime point, which induce an inert adjoint scalar field ϕ ( |ϕ| spatio-temporally constant). The field ϕ , in turn, implies an effective pure-gauge configuration, a gs μ , accurately describing HS (anti)caloron overlap. Spatial homogeneity of the ther ... mehr
