Bound States in Quantum Field Theory
~aP+rr@r = ~~rTorp (84) The mass m though invariant in a Lorentz transformation is not necessarily a constant of the motion, even if the density p of the particle is constant, since m includes the thermodynamic internal energy Lsee Eq. (34)7. Included in the Minkowski force is a term which predicts a force on a particle when it exists in a temperature gradient, a force associated with the entro...
متن کاملNonrelativistic Bound States in Quantum Field Theory∗
Nonrelativistic bound states are studied using an effective field theory. Large logarithms in the effective theory can be summed using the velocity renormalization group. For QED, one can determine the structure of the leading and next-to-leading order series for the energy, and compute corrections up to order α ln α, which are relevant for the present comparison between theory and experiment. ...
متن کاملBoundary bound states in integrable quantum field theory
The purpose of this talk is to sketch some recent progress which has been made in calculating non-perturbatively the reflection factors for the sinh-Gordon model restricted to a half-line by integrable boundary conditions. The essential idea is to calculate the energy spectrum of boundary breathers in two independent ways; firstly by using the boundary bootstrap and secondly by quantizing the c...
متن کاملEntropy bound and local quantum field theory
I comment on Ulvi Yurtsever’s result, which states that the entropy of a truncated bosonic Fock space is given by a holographic bound when the energy of the Fock states is constrained gravitationally. The derivation given in Yurtsever’s paper contains an subtle mistake, which invalidates the result. A more restrictive, non-holographic entropy bound is derived. PACS numbers: 04.70.-s, 03.67.-a
متن کاملScattering and Bound States in Euclidean Lattice Quantum Field Theories
In this paper we study the property of asymptotic completeness in (massive) Euclidean lattice quantum field theories. We use the methods of Spencer and Zirilli [2] to prove, under suitable hypothesis, two-body asymptotic completeness, i.e., for the energy range just above the two-particle threshold.
