On the Spectrum of a Model Operator in Fock Space
Tulkin H. Rasulov, Mukhiddin I. Muminov, Mahir Hasanov
A model operator associated to a system describing four particles in interaction, without conservation of the number of particles, is considered. We describe the essential spec…
On the spectrum of an Hamiltonian in Fock space. Discrete spectrum Asymptotics
Sergio Albeverio, Saidakhmat N. Lakaev, Tulkin H. Rasulov
A model operator associated with the energy operator of a system describing three particles in interaction, without conservation of the number of particles, is considered. The…
The number of eigenvalues for an Hamiltonian in Fock space
Sergio Albeverio, Saidakhmat N. Lakaev, Tulkin H. Rasulov
A model operator corresponding to the energy operator of a system with non-conserved number of particles is considered. The precise location and structure of the esse…
