Purely Magnetic Spacetimes
Spacetimes in which the electric part of the Weyl tensor vanishes (relative to some timelike unit vector field) are said to be purely magnetic. Examples of purely magnetic spacetimes are known and are relatively easy to construct, if no restrictions are placed on the energy-momentum tensor. However it has long been conjectured that purely magnetic vacuum spacetimes (with or without a cosmologic...
متن کاملPurely Magnetic Spacetimes
Purely magnetic spacetimes, in which the Riemann tensor satisfies Rabcdu b u d = 0 for some unit timelike vector u, are studied. The algebraic consequences for the Weyl and Ricci tensors are examined in detail and consideration given to the uniqueness of u. Some remarks concerning the nature of the congruence associated with u are made. ∗ Email:[email protected]
متن کاملConfining quantum particles with a purely magnetic field
We consider a Schrödinger operator with a magnetic field (and no electric field) on a domain in the Euclidean space with a compact boundary. We give sufficient conditions on the behavior of the magnetic field near the boundary which guarantees essential self-adjointness of this operator. From the physical point of view, it means that the quantum particle is confined in the domain by the magneti...

متن کاملVirtual Contact: the Continuum from Purely Visual to Purely Physical
Providing appropriate cues to users when interacting with objects in immersive virtual environments (IVEs) is a difficult task. In addition to individual user differences, environmental factors, and task-specific requirements, the technological complexity of the current state of the art in haptic feedback further increases the difficulty. Though the technology continues to improve, we are still...
