Real and imaginary - time QQ correlators in a thermal medium
We investigate the behavior of a pair of heavy fermions, denoted by Q and Q̄, in a hot/dense medium. Although we have in mind the situation where Q and Q̄ denote heavy quarks, our treatment will be limited to simplified models, which bear only some general similarities with QCD. We study in particular the limiting case where the mass of the heavy fermions is infinite. Then a number of results can...
متن کاملReal-Time Correlators and Non-Relativistic Holography
We consider Lorentzian correlation functions in theories with non-relativistic Schrödinger symmetry. We employ the method developed by Skenderis and van Rees in which the contour in complex time defining a given correlation function is associated holographically with the gluing together of Euclidean and Lorentzian patches of spacetimes. This formalism extends appropriately to geometries with Sc...
متن کاملImaginary parts and discontinuities of Wilson line correlators.
We introduce a notion of position-space cuts of eikonal diagrams, the set of diagrams appearing in the perturbative expansion of the correlator of a set of straight semi-infinite Wilson lines. The cuts are applied directly to the position-space representation of any such diagram and compute its imaginary part to the leading order in the dimensional regulator. Our cutting prescription thus defin...
متن کاملReal -Time Pricing Design Considering Uncertainty of Renewable Energy Resources and Thermal Loads in Smart Grids
In this paper, a novel real time pricing design is presented for Demand Response (DR) programs. A Load Serving Entity (LSE) is responsible to provide energy for flexible loads, inflexible loads and thermal loads. The LSE consider operation conditions of system and uncertainty of renewable energy resources and it designs a Real Time Price (RTP) demand response. The inflexible and thermal loads c...
متن کاملHolographic real-time nonrelativistic correlators at zero and finite temperature
We compute a variety of two and three-point real-time correlation functions for a strongly-coupled nonrelativistic field theory. We focus on the theory conjectured to be dual to the Schrödinger-invariant gravitational spacetime introduced by Balasubramanian, McGreevy, and Son, but our methods apply to a large class of nonrelativistic theories. At zero temperature, we obtain time-ordered, retard...
