“…Recently, superradiant effects in two-dimensional electron gases (2DEGs) have been brought into attention 9- 15 . In the original Dicke model, the coherence is obtained because single sources are within the distance smaller than the wavelength of the radiation.…”

“…In 2DEGs the effects of the superradiance may be easily monitored experimentally, e.g. by varying the temperature or gate voltage.The main experimental procedure to investigate the superradiance in 2DEGs is based on the time-domain terahertz spectroscopy 9,[11][12][13]15 . Within this technique 17 the cyclotron resonance is excited by a short terahertz pulse and the free decay of the electronic system is directly recorded in the time domain.…”

Superradiant and transport lifetimes of the cyclotron resonance in the topological insulator HgTe

We investigate the superradiance effects in three-dimensional topological insulator HgTe with conducting surface states. We demonstrate that the superradiance can be explained using the classical electrodynamic approach. Experiments using the continuous-wave spectroscopy allowed to separate the energy losses in the system into intrinsic and radiation losses, respectively. These results demonstrate that the superradiance effects are not sensitive to the details of the band structure of the material.

We investigate the rate of superradiant emission for a number of artificial atoms (qubits) embedded in a one-dimensional open waveguide. More specifically, we study the 1D (N+1)-qubit chain where N qubits are identical in respect to their excitation frequency Ω but have different rates of spontaneous emission Γn, and a single impurity qubit which is different from N qubits by its excitation frequency ΩP and rate of spontaneous emission ΓP . This system is shown to have two hybridized collective states which accumulates the widths of all qubits. The energy spectrum of these states and corresponding probabilities are investigated as the function of the frequency detuning between the impurity and other qubits in a chain. It is shown that the inclusion of impurity qubit alter the resonance widths of the system only in a narrow range of the frequency detuning between qubits and impurity, where the resonance widths experience a significant repulsion. The photon transmission through disordered N-qubit chain with impurity qubit is also considered. It is shown that a single photon transport through this system is described by a simple expression which predicts for specific photon frequency the existence of a complete transmission peak and transparency window between frequencies Ω and ΩP .

One-dimensional structures of non-Hermitian plasmonic metallic nanospheres are studied in this paper. For a single sphere, solving Maxwell's equations results in quasi-stationary eigenmodes with complex quantized frequencies. Coupled mode theory is employed in order to study more complex structures. The similarity between the coupled mode equations and the effective non-Hermitian Hamiltonians governing open quantum systems allows us to translate a series of collective phenomenon emerging in condensed matter and nuclear physics to the system of plasmonic spheres. A nontrivial physics emerges as a result of strong non-radiative near field coupling between adjacent spheres. For a system of two identical spheres, this occurs when the width of the plasmonic resonance of the uncoupled spheres is twice the imaginary component of the coupling constant. The two spheres then become coupled through a single continuum channel and the effect of coherent interaction between the spheres becomes noticeable. The eigenmodes of the system fall into two distinct categories: superradiant states with enhanced radiation and dark states with no radiation. The transmission through one-dimensional chains with an arbitrary number of spheres is also considered within the effective Hamiltonian framework which allows us to calculate observables such as the scattering and transmission amplitudes. This nano-scale waveguide can undergo an additional superradiance phase transition through its coupling to the external world. It is shown that perfect transmission takes place when the superradiance condition is satisfied.
