Negative Energy, Superluminosity and Holography
The holographic connection between large N Super Yang Mills theory and gravity in anti deSitter space requires unfamiliar behavior of the SYM theory in the limit that the curvature of the AdS geometry becomes small. The paradoxical behavior includes superluminal oscillations and negative energy density. These effects typically occur in the SYM description of events which take place far from the...
متن کاملTransitions into the negative-energy Dirac continuum
We compare the predictions of the single-particle Dirac equation with quantum field theory for an electron subjected to a space and time dependent field. We demonstrate analytically and numerically that a transition into the negative-energy subspace predicted by the single-particle Dirac equation is directly associated with the degree of suppression of pair-production as described by quantum fi...
متن کاملMeasurements, errors, and negative kinetic energy.
An analysis of errors in measurement yields new insight into the penetration of quantum particles into classically forbidden regions. In addition to “physical” values, realistic measurements yield “unphysical” values which, we show, can form a consistent pattern. An experiment to isolate a particle in a classically forbidden region obtains negative values for its kinetic energy. These values re...
متن کاملA commercialization strategy for carbon-negative energy
The Intergovernmental Panel on Climate Change (IPCC) envisages the need for large-scale deployment of net-negative CO2 emissions technologies by mid-century to meet stringent climate mitigation goals and yield a net drawdown of atmospheric carbon. These CO2 removal technologies complement lowor zero-carbon energy technologies1,2. Industrial-scale sequestration of CO2 from bioenergy production —...
متن کاملCreating Naked Singularities and Negative Energy
A brief review is given of three recent results concerning classical solutions of gravitational theories: (1) With asymptotically anti de Sitter boundary conditions, there are matter theories satisfying the positive energy theorem which violate cosmic censorship. (2) Despite supersymmetry, there are solutions to N = 8 supergravity in which the total gravitational energy is arbitrarily negative....
