- Abstract summary: Annealing is the process of gradually lowering the temperature of a system to guide it towards its lowest energy states.
We show how to bound the two case-specific quantities appearing in the bound, namely the activity, a measure of the number of microstate jumps, and the change in relative entropy between the state and the instantaneous thermal state.

- Abstract: Annealing is the process of gradually lowering the temperature of a system to
guide it towards its lowest energy states. In an accompanying paper [Luo et al.
Phys. Rev. E 108, L052105 (2023)], we derived a general bound on annealing
performance by connecting annealing with stochastic thermodynamics tools,
including a speed-limit on state transformation from entropy production. We
here describe the derivation of the general bound in detail. In addition, we
analyze the case of simulated annealing with Glauber dynamics in depth. We show
how to bound the two case-specific quantities appearing in the bound, namely
the activity, a measure of the number of microstate jumps, and the change in
relative entropy between the state and the instantaneous thermal state, which
is due to temperature variation. We exemplify the arguments by numerical
simulations on the SK model of spin-glasses.

We propose to use quantum information notions to characterize thermally induced melting of nonperturbative bound states at high temperatures.
An equilibrium signature of meson melting is identified in the temperature dependence of the thermal-state second R'enyi entropy.
These analyses bring new ways of describing in-medium meson phenomena in quantum many-body and high-energy physics.
