The Renormalization of the Energy-momentum Tensor for an Effective Initial State
The new physics quantum state their differences
2014/12/20
An effective description of an initial state is a method for representing the signatures of new physics in the short-distance structure of a quantum state. The expectation value of the energy-momentum...
The Energy-Momentum tensor on low dimensional $\Spinc$ manifolds
Spinc structures Dirac operator eigenvalues Energy-Momentum tensor compact surfaces isometric immersions
2012/4/18
On a compact surface endowed with any $\Spinc$ structure, we give a formula involving the Energy-Momentum tensor in terms of geometric quantities. A new proof of a B\"{a}r-type inequality for the eige...

On electromagnetism generalized energy-momentum tensor electromagnetic field spaces Finsler geometry
2011/1/20
By using variational calculus and exterior derivative formalism, we proposed in [30] and [11] a new geometric approach to electromagnetism in pseudo-Finsler spaces.

The Energy-Momentum tensor on $Spin^c$ manifolds
The Energy-Momentum tensor $Spin^c$ manifolds
2010/11/8
On $Spin^c$ manifolds, we study the Energy-Momentum tensor associated with a spinor field. First, we give a spinorial Gauss type formula for oriented hypersurfaces of a $Spin^c$ manifold. Using the no...
Do the Ricci and energy-momentum tensors have "duality'' in the context of their Lie symmetries?
Ricci energy-momentum tensors
2010/12/20
The Ricci and energy-momentum tensors have the same algebraic sym-metries. In the Einstein equations they look “dual” to each other, in that interchang-ing them and inverting the gravitational couplin...
The matter Lagrangian and the energy-momentum tensor in modified gravity with non-minimal coupling between matter and geometry
energy-momentum tensor modified gravity non-minimal coupling
2010/3/18
We show that in modified $f(R)$ type gravity models with non-minimal coupling between matter and geometry, both the matter Lagrangian, and the energy-momentum tensor, are completely and uniquely deter...

Review Article - Classification of Energy Momentum Tensors in n ≥ 5 Dimensional Space-times: A Review
Energy Momentum Tensors n ≥ 5 Dimensional Space-times
2010/10/21
Recent developments in string theory suggest that there might exist extra spatial dimensions, which are not small nor compact. The framework of a great number of brane cosmological models is that in w...
On the Trace Anomaly and the Energy-Momentum Conservation of Quantum Fields at D=2 in Classical Curved Backgrounds
the Energy-Momentum Conservation Quantum Fields Classical Curved Backgrounds
2010/10/21
We study the conformal symmetry and the energy-momentum conservation of scalar field interacting with a curved background at D = 2. We avoid to incorporate the metric determinant into the measure of t...
