A remark on the subleading order in the asymptotics of the nonequilibrium emptiness formation probability

We study the asymptotic behavior of the emptiness formation probability for large spin strings in a translation invariant quasifree nonequilibrium steady state of the isotropic XY chain. Besides the overall exponential decay, we prove that, out of equilibrium, the exponent of the subleading power law contribution to the asymptotics is nonvanishing and strictly positive due to the singularities in the density of the steady state.Comment: 20 pages, 2 figure

Use of fine unheated wires in shock tubes

Some preliminary measurements of heat transfer to fine unheated wires have been made in the shock tube. These measurements show that the response of the wire is nearly exponential with time

From the microscopic to the van Hove regime in the XY chain out of equilibrium

Using the framework of rigorous algebraic quantum statistical mechanics, we construct the unique nonequilibrium steady state in the isotropic XY chain in which a sample of arbitrary finite size is coupled by a bond coupling perturbation of arbitrary strength to two infinitely extended thermal reservoirs, and we prove that this state is thermodynamically nontrivial. Moreover, extracting the leading second order contribution to its microscopic entropy production and deriving its entropy production in the van Hove weak coupling regime, we prove that, in the mathematically and physically important XY chain, the van Hove regime reproduces the leading order contribution to the microscopic regime.Comment: 44 pages, 2 figure

The University of North Carolina Intergenerational Legal Ethics Project: Expanding the Contexts for Teaching Professional Ethics and Values

The University of North Carolina Law School Intergenerational Legal Ethics Project (UNC Project) is an effort to identify new course concepts and structures and other curricular innovations that can bring education in professional values to a deeper, more personal level. The UNC project includes the premise that ethical learning is deep, internal learning
