The 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, ...
متن کاملA non-trivial spectrum for the trivial λφ theory
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...
متن کاملA non-trivial example of a trivial strongly analytic multifunction
Using a construction similar to an iterated function system, but with functions changing at each step of iteration, we provide a natural example of a continuous one-parameter family of holomorphic functions of infinitely many variables. This family is parametrized by the compact space of positive integer sequences of prescribed growth and hence it can also be viewed as a parametric description ...
متن کاملTrivial Stable Structures with Non-trivial Reducts
We offer a new viewpoint on some of the generic structures constructed using Hrushovski’s predimensions and show that they are natural reducts of quite straightforward trivial, one-based stable structures. 2000 Mathematics Subject Classification: 03C45.
متن کاملNon-Trivial t-Intersection in the Function Lattice
The function lattice, or generalized Boolean algebra, is the set of `-tuples with the ith coordinate an integer between 0 and a bound ni. Two `-tuples t-intersect if they have at least t common nonzero coordinates. We prove a Hilton–Milner type theorem for systems of t-intersecting `-tuples.
