Spontaneous emission of a moving atom in the presence of magnetodielectric material: A relativistic approach
Fariba Shafieiyan, Ehsan Amooghorban, Ali Mahdifar
In this paper, based on a canonical quantization scheme, we study the effect of the relativistic motion of an excited atom on its decay rate in the presence of absorbing and disper…
Entanglement of two two-levels atoms mediated by an optical black hole
Mahnaz Tavakoli, Ehsan Amooghorban
We consider the dynamics of a system consisting of two two-level atoms interacting with the electromagnetic field near an optical black hole. We obtain the reduced density operator…
Entanglement dynamics of two two-level atoms in the vicinity of an invisibility cloak
Ehsan Amooghorban, Elnaz Aleebrahim
We study the entanglement between two identical two-level atoms located near an ideal model of invisibility cloaks, by monitoring the the time evolution of the concurrence measure.…
Wireless Information and Power Transfer in Full-Duplex Systems with Massive Antenna Arrays
Mohammadali Mohammadi, Batu K. Chalise, Himal A. Suraweera +1
We consider a multiuser wireless system with a full-duplex hybrid access point (HAP) that transmits to a set of users in the downlink channel, while receiving data from a set of en…
Origin of magnetic frustration in BiMnO(NO)
Mojtaba Alaei, Hamid Mosadeq, Ismail Abdolhossaini Sarsari +1
BiMnO(NO) (BMNO) is a honeycomb bilayers anti-ferromagnet, not showing any ordering down to very low temperatures despite having a relatively large Curie-Weiss t…
Stars versus stripes Ramsey numbers
G. R. Omidi, G. Raeisi, Z. Rahimi
For given simple graphs , the Ramsey number is the smallest positive integer such that if the edges of the complete graph $K_…
