Spectral and scattering theory for some abstract QFT Hamiltonians
We introduce an abstract class of bosonic QFT Hamiltonians and study their spectral and scattering theories. These Hamiltonians are of the form H = dΓ(ω) + V acting on the bosonic Fock space Γ(h), where ω is a massive one-particle Hamiltonian acting on h and V is a Wick polynomial Wick(w) for a kernel w satisfying some decay properties at infinity. We describe the essential spectrum of H , prov...
متن کاملSpectral theory of no-pair Hamiltonians
We prove a HVZ theorem for a general class of no-pair Hamiltonians describing an atom or positively charged ion with several electrons in the presence of a classical external magnetic field. Moreover, we show that there exist infinitely many eigenvalues below the essential spectrum and that the corresponding eigenfunctions are exponentially localized. The novelty is that the electrostatic and m...
متن کاملGravitational scattering of massless scalars in QFT and superstring theory
In this paper we perform the calculation of the gravitational scattering amplitude for 4 massless scalars in quantum field theory and Type II superstring theory. We show that the results agree, providing an example of how gravity is incorporated in the superstring theory. During the calculation we quantize gravitational action to derive graviton propagator and interaction vertex with massless s...
متن کاملSome Problems of Spectral Theory
Also compact operators of scalar type in any Banach can be so expressed, provided, the sum (1) is allowed to be countably infinite. It is perhaps less often noted that any operator of scalar type can be expressed in the form (1), with the index j running over all positive integers. But, in general, the projections P. cannot be chosen pair-wise J disjoint, that is, the product of any distinct pa...
متن کاملLow energy spectral and scattering theory for relativistic Schrödinger operators
Spectral and scattering theory at low energy for the relativistic Schrödinger operator are investigated. Some striking properties at thresholds of this operator are exhibited, as for example the absence of 0-energy resonance. Low energy behavior of the wave operators and of the scattering operator are studied, and stationary expressions in terms of generalized eigenfunctions are proved for the ...
