Quantum interference near graphene layers: Observing the surface plasmons with transverse electric polarization

Abstract

The spontaneous emission of a V-type three-level quantum emitter near graphene layers is investigated. With appropriate doping densities, graphene layers support transverse electric- (TE-) polarized surface plasmons. This kind of plasmon can enhance the decay rates of dipoles parallel to the layers, and subsequently, strong quantum interference presents between the two orthogonal transition dipoles of the emitter. As a result, the emission field polarization and the spectrum can be radically changed. This can be evidence of the TE-polarized surface plasmons in the graphene layers.

Spontaneous emission interference enhancement with a μ -negative metamaterial slab

Xiaodong Zeng, Jingping Xu, Yaping Yang

The spontaneous decay and quantum interference of a $\mathsf{V}$-type Zeeman atom placed near a $\ensuremath{\mu}$-negative metamaterial (MNG) slab are investigated. Based on the fact that MNG slab supports only TE-polarized surface-plasmon polariton (SPP) modes, the decay rate of the dipole component parallel to the interface would be much larger than that normal to the interface, because one can couple while another decouple to TE modes. Consequently, high-level anisotropic environment is created and the two dipoles can interfere with each other strongly by sharing such SPP modes even if they are orthogonal. In our work, we analyze the influence of the parameters of the MNG slab as well as the atomic location on the interference intensity in detail. In addition, the dissipation of the slab is considered, and the quantum interference is still excellent even with large absorption.

Plasmon-Induced Enhancement of Quantum Interference near Metallic Nanostructures

Vassilios Yannopapas, Emmanuel Paspalakis, Nikolay V. Vitanov

We show that the quantum interference between two spontaneous emission channels can be greatly enhanced when a three-level V-type atom is placed near plasmonic nanostructures such as metallic slabs, nanospheres, or periodic arrays of metal-coated spheres. The spontaneous emission rate is calculated by a rigorous first-principles electromagnetic Green's tensor technique. The enhancement of quantum interference is attributed to the strong dependence of the spontaneous emission rate on the orientation of an atomic dipole relative to the surface of the nanostructure at the excitation frequencies of surface plasmons.

Quantum interference near bismuth-chalcogenide microstructures

Dimitrios E. Karaoulanis, Emmanuel Paspalakis, Vassilios Yannopapas

In this work, we show that the quantum interference between two spontaneous emission channels can be greatly enhanced when a three-level V-type quantum emitter is placed near the bismuth chalcogenide ( B i 2 T e 3 ). Namely, we calculated the degree of quantum interference for quantum emitters placed in the vicinity of a planar surface of a B i 2 T e 3 slab, as well as near a B i 2 T e 3 microsphere. We found, in particular, that the degree of quantum interference assumes very high values, for both geometries, which is a result of the strong dependence of the spontaneous emission rate on the orientation of a quantum-emitter dipole relative to the B i 2 T e 3 surface, at the frequencies of polaritonic-type excitations. These particular high values of quantum interference can trigger a variety of phenomena associated with quantum interference of spontaneous-emission channels, such as lasing without inversion, coherent populations trapping, transparency, nonlinearities, and so forth.

Quantum interference of spontaneous-emission channels near the surface of Bi2Se3

Dimitrios E. Karaoulanis, Vassilios Yannopapas

We show that the quantum interference between two spontaneous emission channels can be significantly enhanced when a three-level V-type atom is placed near the surface of the topological insulator [Formula: see text]. The enhancement of quantum interference is a result of the strong dependence of the spontaneous emission rate on the orientation of an atomic dipole relative to surface of the [Formula: see text] at the frequencies of polaritonic-type excitations.

Nonlinear Atom-Plasmon Interactions Enabled by Nanostructured Graphene

Joel D. Cox, F. Javier Garcı́a de Abajo

Electrically tunable graphene plasmons are anticipated to enable strong light-matter interactions with resonant quantum emitters. However, plasmon resonances in graphene are typically limited to infrared frequencies, below those of optical excitations in robust quantum light sources and many biologically interesting molecules. Here we propose to utilize near fields generated by the plasmon-assisted nonlinear optical response of nanostructured graphene to resonantly couple with proximal quantum emitters operating in the near infrared. We show that the nonlinear near field produced by a graphene nanodisk can strongly excite and coherently control quantum states in two- and three-level atomic systems when the third harmonic of its plasmon resonance is tuned to a particular electronic transition. In the present scheme, emitter and plasmon resonances are nondegenerate, circumventing strong enhancement of spontaneous emission. We envision potential applications for the proposed nonlinear plasmonic coupling scheme in sensing and temporal quantum control.

Dynamic control of resonance fluorescence in graphene quantum plasmonics

Ali A. Kamli, Sergey A. Moiseev, Jabir Wali Hakami

The spectral and statistical properties are explored for surface plasmon (SP) emission in resonance fluorescence from a driven two level emitter in the proximity of 2D single graphene sheet. We derive an exact closed form analytic expression for the emitted SP field valid in the near and far regions. The SP field profile and spectrum function depend on the graphene conductivity and take into account the dynamic control parameters, namely Fermi energy. We present analysis for the spectrum and second order coherence functions and discuss the possibility of their control using graphene system parameters to manipulate the spectral linewidth and second order coherence function.
