On Conserved Quantities for the Schwarzschild Black Hole in Teleparallel Gravity
E. D. Emtsova, M. Krššák, A. N. Petrov +1
We examine various methods of constructing conserved quantities in the Teleparallel Equivalent of General Relativity (TEGR). We demonstrate that in the covariant formulation the pr…
Conformal Gravity and Transformations in the Symmetric Teleparallel Framework
Viktor Gakis, Martin Krššák, Jackson Levi Said +1
Conformal symmetries appear in many parts of physics and play a unique role in exploring the Universe. In this work, we consider the possibility of constructing conformal theories…
Flat connection for rotating vacuum spacetimes in extended teleparallel gravity theories
Laur Järv, Manuel Hohmann, Martin Krššák +1
Teleparallel geometry utilizes Weitzenböck connection which has nontrivial torsion but no curvature and does not directly follow from the metric like Levi-Civita connection. In ext…
Teleparallel Theories of Gravity: Illuminating a Fully Invariant Approach
M. Krssak, R. J. van den Hoogen, J. G. Pereira +2
Teleparallel gravity and its popular generalization gravity can be formulated as fully invariant (under both coordinate transformations and local Lorentz transformations) th…
New classes of modified teleparallel gravity models
Sebastian Bahamonde, Christian G. Boehmer, Martin Krssak
New classes of modified teleparallel theories of gravity are introduced. The action of this theory is constructed to be a function of the irreducible parts of torsion $f(T_{\rm ax}…
Variational Problem and Bigravity Nature of Modified Teleparallel Theories
Martin Krssak
We consider the variational principle in the covariant formulation of modified teleparallel theories with second order field equations. We vary the action with respect to the spin…
The covariant formulation of f(T) gravity
Martin Krššák, Emmanuel N. Saridakis
We show that the well-known problem of frame dependence and violation of local Lorentz invariance in the usual formulation of gravity is a consequence of neglecting the role…
Exploring Higher-Order Gravitational Waves
H. Arcos, M. Krssak, J. G. Pereira
In addition to the usual linear gravitational waves in transverse-traceless coordinates, higher-order gravitational field equations, as well as their corresponding solutions, are e…
Spin Connection and Renormalization of Teleparallel Action
Martin Krššák, J. G. Pereira
In general relativity, inertia and gravitation are both included in the Levi-Civita connection. As a consequence, the gravitational action, as well as the corresponding energy-mome…
Energy Momentum Tensor Correlators in Improved Holographic QCD
Martin Krssak
In this thesis, we study the physics of the quark gluon plasma (QGP) using holographic methods borrowed from string theory. We start our discussion by motivating the use of such ma…
Viscosity Correlators in Improved Holographic QCD
Martin Krssak
We study a bottom-up holographic model of large-Nc Yang-Mills theory, in which conformal invariance is broken through the introduction of a dilaton potential on the gravity side. W…
Energy momentum tensor correlators in hot Yang-Mills theory: holography confronts lattice and perturbation theory
K. Kajantie, Martin Krssak, Aleksi Vuorinen
We investigate the behavior of energy momentum tensor correlators in strongly coupled large-N_c Yang-Mills theory at nonzero temperature, working within the Improved Holographic QC…
Bulk and shear spectral functions in weakly and strongly coupled Yang-Mills theory
Aleksi Vuorinen, Martin Krssak, Yan Zhu
In this talk, we discuss a number of recent calculations aimed at determining the spectral functions corresponding to various components of the energy momentum tensor in high-tempe…
Frequency and wave number dependence of the shear correlator in strongly coupled hot Yang-Mills theory
K. Kajantie, Martin Krssak, M. Vepsalainen +1
We use AdS/QCD duality to compute the finite temperature Green's function G(omega,k;T) of the shear operator T_12 for all omega,k in hot Yang-Mills theory. The goal is to assess ho…
