Note on holographic torus stress tensor correlators in AdS 3 gravity
Journal of High Energy PhysicsIn the AdS3/CFT2 framework, the Euclidean BTZ black hole corresponds to the dominant high-temperature phase of its dual field theory. We initially employ perturbative methods to solve the Einstein equations as boundary value problems, providing ...

Fate of spin polarization in a relativistic fluid: An entropy-current analysis
Physics Letters B, 2019 We derive relativistic hydrodynamic equations with a dynamical spin degree of freedom on the basis of an entropy-current analysis. The first and second laws of local thermodynamics constrain possible structures of the constitutive relations including a ...

Energy-momentum tensor of perturbed tachyon matter [PDF]
Physical Review D, 2009 We add an initial nonhomogeneous perturbation to an otherwise homogeneous condensing tachyon background and compute its space time energy-momentum tensor from worldsheet string theory. We show that in the far future the energy-momentum tensor corresponds to nonhomogeneous pressureless tachyon matter.

Scale transformations, the energy-momentum tensor, and the equation of state [PDF]
, 1989 The Equation of State (EOS) relates diagonal elements of the energy-momentum tensor {theta}{sub {mu}{nu}}. The first moment of the energy-momentum tensor generates scale transformations.

Advanced Science, EarlyView.Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

The gravitational energy-momentum pseudo-tensor of conformally invariant theories of gravity
Journal of High Energy PhysicsWe construct the gravitational energy-momentum pseudo-tensor of up to fourth-order conformally invariant theories of gravity. Then we linearize the pseudo-tensor and use its average over a macroscopic region to find the energy and momentum carried by the

Partonic angular momentum in the nucleon's chiral periphery
Physics Letters B, 2019 We study the nucleon's partonic angular momentum (AM) content at peripheral transverse distances b=O(Mπ−1), where the structure is governed by chiral dynamics.

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review
Advanced Science, EarlyView.Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Self-gravitating field configurations: The role of the energy–momentum trace
Physics Letters B, 2014 Static spherically-symmetric matter distributions whose energy–momentum tensor is characterized by a non-negative trace are studied analytically within the framework of general relativity.

The gravitational energy-momentum for the super-energy Bel-Robinson tensor [PDF]
, 2023 Describing the gravitational energy-momentum, the super-energy Bel-Robinson tensor is the best candidate. In the past, people seems only explore the lowest order: the electric part $E_{ab}$ and magnetic part $B_{ab}$ for the Riemann tensor.
