Thermodynamics. ‌ For each process, changes in internal energy (U), enthalpy (H), entropy (S), and ▇▇▇▇▇ free energy (G) are calculated. In addition the zero-point energy (ZPE) is calculated. More details behind the derivation of the different formulae can be found in for instance the book by ▇▇▇▇▇▇▇▇▇ and Simon1. For a temperature T = 0 K the following expression fully describes the energetics and thermodynamics of the system (neglecting configurational entropy): 𝑈 = 𝐻 = 𝐺 = 𝐸𝑒𝑙 + 𝐸𝑍𝑃𝐸 with Eel and EZPE defined in the previous section. For all temperatures T > 0 K expressions for the different quantities are given below. The internal energy is calculated from electronic and vibrational contributions (and also rotational and translational contributions for gas phase species): 𝑈𝑠𝑜𝑙𝑖𝑑 = 𝑈𝑒𝑙 + 𝑈𝑣𝑖𝑏

Thermodynamics. ‌ 1) in the presence of a finite boundary. One motivation for studying the finite boundary case is that certain geometries, such as the static patch of de Sitter space, do not afford an asymptotic boundary. In such circumstances, it is natural to consider a Dirichlet problem with a finite boundary. Our goal here is to present formulae for thermodynamic quantities at a finite boundary, gen- eralising the results of [56, 118, 119]. We now evaluate the on-shell Euclidean action, which is related to the partition function by −SE = log Z. Given the Dirichlet problem under consideration, we have that Z is a function of ϕb and βT . The induced metric h and ϕb at ∂M are given by bdy = ℓ2N (rb, rh)dτ 2 ≡ h dτ 2 , βT = β√N (rb, rh) , ϕb = rb . (1.12) The trace of the extrinsic curvature is 1 1 K = h Kττ = 2√h ∂rb N (rb, rh) . (1.13) We will further assume, for now, that the dilaton takes its minimal value at the Euclidean black hole horizon rh. This is not necessarily the case; when the horizon is cosmological it will be located at the largest possible value of the dilaton, as will be discussed in the next section. The on-shell action is SE =
