Infrared properties of boundaries in 1-d quantum systems
Daniel Friedan, Anatoly Konechny
We present some partial results on the general infrared behavior of bulk-critical 1-d quantum systems with boundary. We investigate whether the boundary entropy, s(T), is always bo…

On the Boundary Entropy of One-dimensional Quantum Systems at Low Temperature
Daniel Friedan, Anatoly Konechny
The boundary beta-function generates the renormalization group acting on the universality classes of one-dimensional quantum systems with boundary which are critical in the bulk bu…

Two talks on a tentative theory of large distance physics
Daniel Friedan
These talks present an overview of a tentative theory of large distance physics. For each large distance L (in dimensionless units), the theory gives two complementary descriptions…
