State dependence of Krylov complexity in 2d CFTs

Journal of High Energy Physics, 2023
We compute the Krylov Complexity of a light operator O $$ \mathcal{O} $$ L in an eigenstate of a 2d CFT at large central charge c. The eigenstate corresponds to a primary operator O $$ \mathcal{O} $$ H under the state-operator correspondence.

N=4 Yang--Mills theory as a complexification of the N=2 theory

, 2009
A complexification of the twisted $\N=2$ theory allows one to determine the N=4 Yang--Mills theory in its third twist formulation. The imaginary part of the gauge symmetry is used to eliminate two scalars fields and create gauge covariant longitudinal ...

Micromechanical Characterization of 316L‐V4E Steel Transitions Produced by Electron Beam Powder Bed Fusion with Dual‐Hopper Alternating Layer Strategy

Advanced Engineering Materials, EarlyView.
This work applies High‐Speed Nanoindentation to study multi‐material transitions in powder bed fusion–electron beam melting components. The aim is to assess the mechanical gradients and interfacial behavior between American iron and steel institute 316L stainless steel and V4E tool steel in additively manufactured structures.

Lorentz gauge theory as a model of emergent gravity

, 2012
We consider a class of Lorentz gauge gravity theories within Riemann-Cartan geometry which admits a topological phase in the gravitational sector.

Emission of linearly polarized photons in a strongly coupled magnetized plasma from the gauge/gravity correspondence

Physics Letters B, 2021
We use holographic methods to show that photons emitted by a strongly coupled plasma subject to a magnetic field are linearly polarized regardless of their four-momentum, except when they propagate along the field direction. The gravitational dual is constructed using a 5D truncation of 10-dimensional type IIB supergravity, and includes a scalar field ...

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

Advanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.

Time evolution of entanglement negativity from black hole interiors

Journal of High Energy Physics, 2019
We investigate the time evolution of entanglement negativity following a global quench for mixed state configurations of two disjoint and adjacent intervals in a (1 + 1)-dimensional conformal field theory (CFT 1+1) dual to the eternal black hole sliced ...

Gravity, particle physics and their unification [PDF]

, 2000
We explain the need for a theory of quantum gravity and some general ideas about string theory, including the idea of the derivation of the Hawking Bekenstein entropy formula for extremal black holes.

Formation of Intermetallic Sludge Phases in AlMgSi Alloys with High Concentrations of Alloying Elements: A Drawback for Increasing Sustainability

Advanced Engineering Materials, EarlyView.
Sludge phases with brittle fracture behavior form in AlMgSi alloys with high concentrations of alloying elements and negatively influence their ductility. The phase type mainly depends on the Si content and the concentration of minor alloying elements like Fe, Mn, Cr, and Mo strongly influences the number of sludge particles. The need for sustainable

Gravity dual of two-dimensional N $$ \mathcal{N} $$ = (2, 2)∗ supersymmetric Yang-Mills theory and integrable models

Journal of High Energy Physics, 2018
The 2D N $$ \mathcal{N} $$ = (2, 2)∗ supersymmetric Yang-Mills theory can be obtained from the 2D N $$ \mathcal{N} $$ = (4, 4) theory with a twisted mass deformation.
