Se p 20 06 Enhanced binding for N - particle system interacting with a scalar bose field
نویسندگان
چکیده
An enhanced binding of an N -particle system interacting through a scalar bose field is investigated, where N ≥ 2. It is not assumed that this system has a ground state for a zero coupling. It is shown, however, that there exists a ground state for a sufficiently large values of coupling constants. When the coupling constant is sufficiently large, N particles are bound to each other by the scalar bose field, and are trapped by external potentials. Basic ideas of the proofs in this paper are applications of a weak coupling limit and a modified HVZ theorem.

متن کاملInstitute for Mathematical Physics on Separation of Variables in the Schrr Odinger Equation for a Particle Interacting with External Field on Separation of Variables in the Schrr Odinger Equation for a Particle Interacting with External Eld
We obtain the most general form of the vector-potential of the electromagnetic eld A enabling separation of variables in the (1+2)-dimensional Schrr odinger equation (SE). Using this result we have carried out variable separation for a class of Schrr odinger equations that contains as particular cases SE with Coulomb scalar potential and SE for a particle interacting with the constant magnetic ...
متن کاملScaling Limits for the System of Semi-Relativistic Particles Coupled to a Scalar Bose Field
In this paper the Hamiltonian for the system of semi-relativistic particles interacting with a scalar bose field is investigated. A scaled total Hamiltonian of the system is defined and its scaling limit is considered. Then the semi-relativistic Schrödinger operator with an effective potential is derived.

In this work it is investigated the evolution of a Universe where a scalar field, non-minimally coupled to space-time curvature, plays the role of quintessence and drives the Universe to a present accelerated expansion. A non-relativistic dark matter constituent that interacts directly with dark energy is also considered, where the dark matter particle mass is assumed to be proportional to the ...
