Gravity and global symmetries.
There exists a widely spread notion that gravitational effects can strongly violate global symmetries. If this is correct, it may lead to many important consequences. We will argue, in particular, that nonperturbative gravitational effects in the axion theory lead to a strong violation of CP invariance unless they are suppressed by an extremely small factor g <∼ 10−82. One could hope that this ...
متن کاملQuantum Gravity and Spacetime Symmetries
Small violations of spacetime symmetries have recently been identified as promising Planck-scale signals. This talk reviews how such violations can arise in various approaches to quantum gravity, how the emergent low-energy effects can be described within the framework of relativistic effective field theories, how suitable tests can be identified, and what sensitivities can be expected in curre...
متن کاملApproximate Symmetries and Their Spontaneous Breakdown Approximate Symmetries and Their Spontaneous Breakdown
We propose a rigorous definition of approximate symmetry and of its spontaneous breakdown in connection with a phase transition. We show that this definition is of interest in the case of the Ising model with a small three-spin perturbation.
متن کاملApproximate Symmetries in General Relativity
The problem of finding an appropriate geometrical/physical index for measuring a degree of inhomogeneity for a given space-time manifold is posed. Interrelations with the problem of understanding the gravitational/informational entropy are pointed out. An approach based on the notion of approximate symmetry is proposed. A number of related results on definitions of approximate symmetries known ...
متن کاملApproximate symmetries in dynamical systems
The knowledge of exact symmetries of a diierential problem allows to reduce it, and sometimes to completely solve it; it also allows to obtain exact solutions. If we are looking for approximate rather than exact solutions, then approximate symmetries are as good as exact ones; moreover, they can be determined perturbatively. In this paper we introduce and study approximate symmetries, together ...
