Alpha-invariant of Toric Line Bundles
We generalize the work of Jian Song to compute the alpha invariant of any
(nef and big) toric line bundle in terms of the associated polytope. We use the
analytic version of the computation of the log canonical threshold of monomial
ideals to give the log canonical threshold of any non-negatively curved
singular hermitian metric on the line bundle, and deduce the alpha invariant
from this.Comment: 13 pages. Minor corrections, and references added. Published versio
The second law of thermodynamics at the microscopic scale
In quantum statistical mechanics, equilibrium states have been shown to be
the typical states for a system that is entangled with its environment,
suggesting a possible identification between thermodynamic and von Neumann
entropies. In this paper, we investigate how the relaxation toward equilibrium
is made possible through interactions that do not lead to significant exchange
of energy, and argue for the validity of the second law of thermodynamics at
the microscopic scale.Comment: 3 pages, 1 figur
