Analogue Special and General Relativity by Optical Multilayer Thin Films: The Rindler Space Case
Sh. Dehdashti, R. Roknizadeh, A. Mahdifar
In this paper, to obtain an analogy between the curved spaces and the linear optics, we expand the idea of Ref.[1, 2] to the multilayer films. We investigate efects of thickness an…
Applications of differential algebra for computing Lie algebras of infinitesimal CR-automorphisms
Masoud Sabzevari, Amir Hashemi, Benyamin M. -Alizadeh +1
We perform detailed computations of Lie algebras of infinitesimal CR-automorphisms associated to three specific model real analytic CR-generic submanifolds in C^9 by employing diff…
The Ramsey number of loose paths in 3-uniform hypergraphs
Leila Maherani, Gholamreza Omidi, Ghaffar Raeisi +1
Recently, asymptotic values of 2-color Ramsey numbers for loose cycles and also loose paths were determined. Here we determine the 2-color Ramsey number of 3-uniform loose paths wh…
Quantum optical effective-medium theory for loss-compensated metamaterials
Ehsan Amooghorban, N. Asger Mortensen, Martijn Wubs
A central aim in metamaterial research is to engineer sub-wavelength unit cells that give rise to desired effective-medium properties and parameters, such as a negative refractive…
On three-color Ramsey number of paths
Leila Maherani, Gholamreza Omidi, Ghaffar Raeisi +1
Let be graphs. The multicolor Ramsey number is the smallest positive integer such that if the edges of complete graph are par…
