Enhancement of Quantum Excitation Transport by Photonic Nonreciprocity
S. Ali Hassani Gangaraj, Lei Ying, Francesco Monticone +1
Enhanced interaction between two two-level emitters (e.g., atoms) by nonreciprocal photonic media can be of benefit to broad areas, from quantum information science to biological d…
Non-Markovian Transient Casimir-Polder force and population dynamics on excited and ground state atoms: weak and strong coupling regimes in generally non-reciprocal environments
George W. Hanson, S. Ali Hassani Gangaraj, Mario G. Silveirinha +2
The transient Casimir-Polder force on a two-level atom introduced into a three-dimensional, inhomogeneous, generally non-reciprocal environment is evaluated using non-Markovian Wei…
Spontaneous lateral atomic recoil force close to a photonic topological material
S. Ali Hassani Gangaraj, George W. Hanson, Mauro Antezza +1
We investigate the quantum recoil force acting on an excited atom close to the surface of a nonreciprocal photonic topological insulator (PTI). The main atomic emission channel is…
Fluctuation-induced forces on an atom near a photonic topological material
Mário G. Silveirinha, S. Ali Hassani Gangaraj, George W. Hanson +1
We theoretically study the Casimir-Polder force on an atom in a arbitrary initial state in a rather general electromagnetic environment wherein the materials may have a nonreciproc…
Giant Interatomic Energy-Transport Amplification with Nonreciprocal Photonic Topological Insulators
Pierre Doyeux, S. Ali Hassani Gangaraj, George W. Hanson +1
We show that the energy-transport efficiency in a chain of two-level emitters can be drastically enhanced by the presence of a photonic topological insulator (PTI). This is obtaine…
Robust entanglement with 3D nonreciprocal photonic topological insulators
S. Ali Hassani Gangaraj, George W. Hanson, Mauro Antezza
We investigate spontaneous and pumped entanglement of two level systems in the vicinity of a photonic topological insulator interface, which supports a nonreciprocal (unidirectiona…
Transient and steady-state entanglement mediated by three-dimensional plasmonic waveguides
S. Ali Hassani Gangaraj, Andrei Nemilentsau, George W. Hanson +1
Entanglement between two qubits (two level atoms) mediated by surface plasmons in three-dimensional plasmonic waveguides is studied using a quantum master equation formalism. Two t…
Quantum plasmonic excitation in graphene and robust-to-loss propagation
George W. Hanson, S. A. Hassani Gangaraj, Changhyoup Lee +2
We investigate the excitation of quantum plasmonic states of light in graphene using end-fire and prism coupling. In order to model the excitation process quantum mechanically we q…
