Perelman's W--entropy and Statistical and Relativistic Thermodynamic Description of Gravitational Fields

- Olivia Vacaru, S. Vacaru
- Physics
- 8 December 2013

Using $3+1$ spacetime fibrations on Lorentz manifolds, we define an analogous W--entropy for gravitational fields. Such F- and W-functionals were introduced in the Ricci flow theory of three… Expand

Deforming black hole and cosmological solutions by quasiperiodic and/or pattern forming structures in modified and Einstein gravity

- L. Bubuianu, S. Vacaru
- Physics
- 6 June 2017

We elaborate on the anholonomic frame deformation method, AFDM, for constructing exact solutions with quasiperiodic structure in modified gravity theories, MGTs, and general relativity, GR. Such… Expand

Modified dynamical supergravity breaking and off-diagonal super-Higgs effects

- T. Gheorghiu, Olivia Vacaru, S. Vacaru
- Physics
- 21 November 2013

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 , Hořava type with… Expand

Geometric information flows and G. Perelman entropy for relativistic classical and quantum mechanical systems

- S. Vacaru
- Physics
- 8 May 2019

This work consists an introduction to the classical and quantum information theory of geometric flows of (relativistic) Lagrange--Hamilton mechanical systems. Basic geometric and physical properties… Expand

Entropy functionals for nonholonomic geometric flows, quasiperiodic Ricci solitons, and emergent gravity

- S. Vacaru
- Physics
- 10 March 2019

We investigate gravity models emerging from nonholonomic (subjected to non-integrable constraints) Ricci flows. Considering generalizations of G. Perelman's entropy functionals, relativistic… Expand

SUPERSTRINGS IN HIGHER ORDER EXTENSIONS OF FINSLER SUPERSPACES

- S. Vacaru
- Physics, Mathematics
- 6 November 1996

Abstract The work proposes a general background of the theory of field interactions and strings in spaces with higher order anisotropy. Our approach proceeds by developing the concept of higher order… Expand

Modified dispersion relations in Hořava–Lifshitz gravity and Finsler brane models

- S. Vacaru
- Physics, Mathematics
- 26 October 2010

We study possible links between quantum gravity phenomenology encoding Lorentz violations as nonlinear dispersions, the Einstein–Finsler gravity models, EFG, and nonholonomic (non-integrable)… Expand

Dirac spinor waves and solitons in anisotropic Taub-NUT spaces

- S. Vacaru, Florian Catalin Popa
- Physics, Mathematics
- 31 May 2001

We apply a new general method of anholonomic frames with associated nonlinear connection structure to construct new classes of exact solutions of Einstein–Dirac equations in five-dimensional (5D)… Expand

- Physics, Mathematics
- 6 August 2005

The book contains a collection of works on Riemann-Cartan and metric-affine manifolds provided with nonlinear connection structure and on generalized Finsler-Lagrange and Cartan-Hamilton geometries… Expand
