Exact dynamics of concurrence-based entanglement in a system of four spin-1/2 particles on a triangular ladder structure
Sajedeh Shahsavari, Mostafa Motamedifar, Hassan Safari
Motivated by the ability of triangular spin ladders to implement quantum information processing, we propose a type of such systems whose Hamiltonian includes the XX Heisenberg inte…
Medium-assisted van der Waals dispersion interactions involving chiral molecules
Hassan Safari, Pablo Barcellona, Stefan Yoshi Buhmann +1
The van der Waals dispersion interaction between two chiral molecules in the presence of arbirary magnetoelectric media is derived using perturbation theory. To be general, the mol…
Cavity-QED interactions of two correlated atoms
Saeideh Esfandiarpour, Robert Bennett, Hassan Safari +1
We consider the resonant van der Waals interaction between two correlated identical two-level atoms (at least one of which being excited) within the framework of macroscopic cavity…
Enhanced chiral discriminatory van der Waals interactions mediated by chiral surfaces
Pablo Barcellona, Hassan Safari, A. Salam +1
We predict a discriminatory interaction between a chiral molecule and an achiral molecule which is mediated by a chiral body. To achieve this, we generalize the van der Waals inter…
Body-assisted van der Waals interaction between excited atoms
Hassan Safari, Mohammad Reza Karimpour
We present a formula for the body-assisted van der Waals interaction potential between two atoms, one or both being prepared in an excited energy eigenstate. The presence of arbitr…
Body-assisted dispersion potentials of diamagnetic atoms
Stefan Yoshi Buhmann, Hassan Safari, Stefan Scheel +1
We derive Casimir-Polder and van der Waals potentials of one or two atoms with diamagnetic properties in an arbitrary environment of magnetoelectric bodies. The calculations are ba…
