A rich structure of renormalization group flows for Higgs-like models in 4 dimensions
André LeClair
We consider coupled Higgs doublets which transform in the usual way under SU(2). By constructing marginal operators which satisfy an operator product expansion based on the SU(…

Vacuum energy density from the form factor bootstrap
André LeClair
The form-factor bootstrap is incomplete until one normalizes the zero-particle form factor. For the stress energy tensor we describe how to obtain the vacuum energy density $ρ_{\rm…

Spectral Flow for the Riemann zeros
André LeClair
Recently, with Mussardo we defined a quantum mechanical problem of a single particle scattering with impurities wherein the quantized energy levels are exactly equal to t…

Thermodynamic formulation of vacuum energy density in flat spacetime and potential implications for the cosmological constant
André LeClair
We propose a thermodynamical definition of the vacuum energy density , defined as , in quantum field theory in f…
