Determination of non-local characteristics of density transport in 2D simulations of the SOL
T. Gheorghiu, F. Militello, J. Juul Rasmussen
By use of Lagrangian tracers propagated on 2D simulations of Scrape-Off Layer (SOL) turbulence, we are able to determine the non-local fractional-advection, fractional-diffusion eq…
A portable X-pinch design for x-ray diagnostics of warm dense matter
J. Strucka, J. W. D. Halliday, T. Gheorghiu +13
We describe the design and x-ray emission properties (temporal, spatial, and spectral) of Dry Pinch I, a portable X-pinch driver developed at Imperial College London. Dry Pinch I i…
Geometric Flows and Perelman's Thermodynamics for Black Ellipsoids in and Einstein Gravity Theories
Tamara Gheorghiu, Vyacheslav Ruchin, Olivia Vacaru +1
We study geometric relativistic flow and Ricci soliton equations which (for respective nonholonomic constraints and self-similarity conditions) are equivalent to the gravitational…
Off-Diagonal Deformations of Kerr Black Holes in Einstein and Modified Massive Gravity and Higher Dimensions
Tamara Gheorghiu, Olivia Vacaru, Sergiu I. Vacaru
We find general parameterizations for generic off-diagonal spacetime metrics and matter sources in general relativity (GR) and modified gravity theories when the field equations de…
Modified Dynamical Supergravity Breaking and Off-Diagonal Super-Higgs Effects
Tamara Gheorghiu, Olivia Vacaru, Sergiu Vacaru
We argue that generic off-diagonal vacuum and nonvacuum solutions for Einstein manifolds mimic physical effects in modified gravity theories (MGTs) and encode certain models of the…
