... Condensed matter physics is a remarkable domain where the effects of quantum mechanics combine with the presence of a very large (∼ 1023 ) coupled degrees of freedom. The interplay between these two ingredients leads to the richness of phenomena that we observe in everyday’s materials and which have ...

... However, the existence of a quantum critical point is not a necessary condition to obtain a nonanalytic relation 1E(τ ) [23, 24]. Equation (3), with various values of the exponent η, holds for ramps within gapless phases of several gapless systems [24]. For a continuous bath of harmonic oscillators, ...
