Comment on the cosmological constant for theory in spacetime dimensions
André LeClair
In a recent article we showed that the analog of the cosmological constant in two spacetime dimensions for a wide variety of integrable quantum field theories has the form $Ï_{\rm…

Riemann zeros as quantized energies of scattering with impurities
Andre LeClair, Giuseppe Mussardo
We construct an integrable physical model of a single particle scattering with impurities spread on a circle. The -matrices of the scattering with the impurities are such that t…
