Black Hole Thermodynamics with Dynamical Lambda

摘要: We study evolution and thermodynamics of a slow-roll transition between early late time de Sitter phases, both in the homogeneous case presence black hole, scalar field model with generic potential having maximum positive minimum. Asymptotically future spacetimes are characterized by ADM charges known as cosmological tensions. show that phase has finite tension when oscillation around its minimum is underdamped, while overdamped diverges. compute variation hole horizon areas finding fractional change area proportional to corresponding effective constant. extended first law thermodynamics, including constant, satisfied initial final states, discuss dynamical temperature.
