Replicating physical motion with Minkowskian isorefractive spacetime crystals

چکیده
Abstract Here, we show that isorefractive spacetime crystals with a travelling-wave modulation may mimic rigorously the response of moving material systems. Unlike generic crystals, which are characterized by bi-anisotropic coupling in co-moving frame, exhibit an observer-independent response, resulting isotropic constitutive relations devoid any bianisotropy. We how to take advantage this property calculation band diagrams laboratory frame and study synthetic Fresnel drag. Furthermore, discuss impact considering either Galilean or Lorentz transformation homogenization showing effective is independent considered transformation.

A non-commutative Minkowskian spacetime from a quantum AdS algebra
A quantum deformation of the conformal algebra of the Minkowskian spacetime in (3 + 1) dimensions is identified with a deformation of the (4 + 1)-dimensional AdS algebra. Both Minkowskian and AdS first-order non-commutative spaces are explicitly obtained, and the former coincides with the well known κ-Minkowski space. Next, by working in the conformal basis, a new non-commutative Minkowskian sp...
متن کاملElectromagnetic Field Tensor and Lorentz Force as Consequence of the Geometry of Minkowskian Spacetime
It is a well known fact that the electromagnetic force acting on a charged particle cannot be obtained from Maxwell Equations having, ultimately, an empirical basis (at least from a classical standpoint). This problem have been around for many years, leaving the electromagnetic field (which we have always considered our better understood part of Physics) with an apparent, and rather curious, la...
متن کاملElectromagnetic Field Tensor and Lorentz Force as Consequence of the Geometry of Minkowskian Spacetime
We show that the electromagnetic field tensor and the Lorentz Force are both a natural consequence of the geometric structure of Minkowskian space, being related to infinitesimal boost and rotations in spacetime. The longstanding issue about the apparent empirical origin of the Lorentz Force is clarified.
متن کاملNon-aqueous Isorefractive Pickering Emulsions
Non-aqueous Pickering emulsions of 16-240 μm diameter have been prepared using diblock copolymer worms with ethylene glycol as the droplet phase and an n-alkane as the continuous phase. Initial studies using n-dodecane resulted in stable emulsions that were significantly less turbid than conventional water-in-oil emulsions. This is attributed to the rather similar refractive indices of the latt...
متن کاملOn the Motion of Matter in Spacetime
We argue that the geodesic hypothesis based on auto-parallels of the Levi-Civita connection may need refinement in theories of gravity with additional scalar fields. This argument is illustrated with a reformulation of the Brans-Dicke theory in terms of a spacetime connection with torsion determined dynamically in terms of the gradient of the Brans-Dicke scalar field. The perihelion shift in th...
