Spectral Renormalization Group
Juerg Froehlich, Marcel Griesemer, Israel Michael Sigal
The operator-theoretic renormalization group (RG) methods are powerful analytic tools to explore spectral properties of field-theoretical models such as quantum electrodynamics (QE…

Ground State and Resonances in the Standard Model of Non-relativistic QED
I. M. Sigal
We prove existence of a ground state and resonances in the standard model of the non-relativistic quantum electro-dynamics (QED). To this end we introduce a new canonical transform…

Dynamics of Collective Decoherence and Thermalization
M. Merkli, G. P. Berman, I. M. Sigal
We analyze the dynamics of N interacting spins (quantum register) collectively coupled to a thermal environment. Each spin experiences the same environment interaction, consisting…
