A non-trivial spectrum for the trivial λφ theory
نویسنده
چکیده
It is pointed out that one-component φ theory in four dimensions has a non-perturbative sector that can be studied by means of an exact duality transformation of its Ising limit. This duality maps it to a membrane model. As a consequence, the φ-theory turns out to have, in the broken symmetry phase, a remarkably rich spectrum of physical states corresponding to membrane excitations. A numerical study of the correlators between dual variables allows to evaluate the masses of the first few states.

The Dual Sector of the Λφ 4 Theory in 4d *
The one-component λφ 4 theory in four dimensions in the spontaneously broken symmetry phase has a non-trivial non-perturbative sector which can be studied by means of a duality transformation of its Ising limit. Duality maps this theory to a model of interacting membranes. Physical states correspond to membrane excitations. The way this non-perturbative behaviour can be reconciled with the triv...
متن کاملExistence of non-trivial solutions for fractional Schrödinger-Poisson systems with subcritical growth
In this paper, we are concerned with the following fractional Schrödinger-Poisson system: (−∆s)u + u + λφu = µf(u) +|u|p−2|u|, x ∈R3 (−∆t)φ = u2, x ∈R3 where λ,µ are two parameters, s,t ∈ (0,1] ,2t + 4s > 3 ,1 < p ≤ 2∗ s and f : R → R is continuous function. Using some critical point theorems and truncation technique, we obtain the existence and multiplicity of non-trivial solutions with ...
متن کاملNon - trivial phase structure of φ 4 - theory at finite temperature 1
The effective potential for the local composite operator φ 2 (x) in λφ 4-theory is investigated at finite temperature in an approach based on path-integral lin-earisation of the φ 4-interaction. At zero temperature, the perturbative vacuum is unstable, because a non-trivial phase with a scalar condensate φ 2 0 has lower effective action. Due to field renormalisation, λφ 2 0 is renormalisation g...
متن کاملThe Non-Trivial Effective Potential of the ‘Trivial’ λΦ Theory: A Lattice Test
The strong evidence for the ‘triviality’ of (λΦ)4 theory is not incompatible with spontaneous symmetry breaking. Indeed, for a ‘trivial’ theory the effective potential should be given exactly by the classical potential plus the free-field zero-point energy of the shifted field; i.e., by the one-loop effective potential. When this is renormalized in a simple, but nonperturbative way, one finds, ...

We consider techniques (based on an ultraviolet cutoff) used to prove that the pure boson (φ 4) 4 field theory is trivial and apply them instead to the dynamically generated quark-level linear sigma model. This cutoff approach leads to the conclusion that the latter field theory is in fact nontrivial. Owing to the recent observational identification [1] of a nonstrange scalar σ meson below 1 Ge...
