Classification and quantification of entanglement through wedge product and geometry

Physica Scripta, 2023
Abstract The wedge product of post-measurement vectors of a two-qubit state gives rise to a parallelogram, whose ‘area’ has been shown to be equivalent to the generalized I-concurrence measure of entanglement. In multi-qudit systems, the wedge product of post-measurement vectors naturally leads to a higher dimensional parallelepiped ...

Local density of states at polygonal boundaries of d-wave superconductors [PDF]

, 2005
Besides the well-known existence of Andreev bound states, the zero-energy local density of states at the boundary of a d-wave superconductor strongly depends on the boundary geometry itself.

Study on Surface Configurations and Force Transfer Mechanism of Dual-Wedge Shaped Slips for Liner Hanger

Energies, 2023
The penetration force and depth of the slip teeth are important factors influencing the hanging capacity of liner hanger, which can lead to failure of well cementation.

Turning the Orogenic Switch: Slab‐Reversal in the Eastern Alps Recorded by Low‐Temperature Thermochronology

Geophysical Research Letters, 2021
Many convergent orogens, such as the eastern European Alps, display an asymmetric doubly vergent wedge geometry. In doubly vergent orogens, deepest exhumation occurs above the retro‐wedge.

On the Superradiance of Spin-1 Waves in an Equatorial Wedge around a Kerr Hole [PDF]

, 1999
Recently Van Putten has suggested that superradiance of magnetosonic waves in a toroidal magnetosphere around a Kerr black hole may play a role in the central engine of gamma-ray bursts.

Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC 4151 with IXPE [PDF]

Monthly notices of the Royal Astronomical Society, 2023
We present an X-ray spectropolarimetric analysis of the bright Seyfert galaxy NGC 4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks, complemented with simultaneous XMM–Newton (50 ks) and NuSTAR (100 ks ...

Multiple layers of seismic anisotropy and a low‐velocity region in the mantle wedge beneath Japan: Evidence from teleseismic receiver functions

Geochemistry, Geophysics, Geosystems, 2012
A complete characterization of seismic anisotropy can yield powerful constraints on mantle flow and deformation. This is particularly important for the mantle wedge above subducting slabs, where the geometry of mantle flow remains poorly understood.

Combined Screw and Wedge Dislocations

Universe, 2023
Elastic media with defects are considered manifold with nontrivial Riemann–Cartan geometry in the geometric theory of defects. We obtain the solution of three-dimensional Euclidean general relativity equations with an arbitrary number of linear parallel ...

Damage process of a fiber bundle with a strain gradient [PDF]

, 2008
We study the damage process of fiber bundles in a wedge-shape geometry which ensures a constant strain gradient. To obtain the wedge geometry we consider the three-point bending of a bar, which is modelled as two rigid blocks glued together by a thin ...

Area law unification and the holographic event horizon

Journal of High Energy Physics, 2018
We prove a new, large family of area laws in general relativity, which apply to certain classes of untrapped surfaces that we dub generalized holographic screens.
