“…Massively Fermi-degenerate electrons and holes, which would never occur in atomic-like systems, can lead to many-body enhancement of gain, which induces preferential production of a superfluorescent burst at the Fermi edge [140]. This is still a rapidly progressing field of research, expanding to encompass more and more nontraditional physical situations for SR and SF, such as plasmon excitations [43,61] and exciton-plasmon coupling [170,171], with unique solid-state cavities to create nonintuitive many-body playgrounds [60,169,172].…”

Recent advances in optical studies of condensed matter systems have led to the emergence of a variety of phenomena that have conventionally been studied in the realm of quantum optics. These studies have not only deepened our understanding of light-matter interactions but also introduced aspects of many-body correlations inherent in optical processes in condensed matter systems. This article is concerned with the phenomenon of superradiance (SR), a profound quantum optical process originally predicted by Dicke in 1954. The basic concept of SR applies to a general N -body system where constituent oscillating dipoles couple together through interaction with a common light field and accelerate the radiative decay of the whole system. Hence, the term SR ubiquitously appears in order to describe radiative coupling of an arbitrary number of oscillators in many situations in modern science of both classical and quantum description. In the most fascinating manifestation of SR, known as superfluorescence (SF), an incoherently prepared system of N inverted atoms spontaneously develops macroscopic coherence from vacuum fluctuations and produces a delayed pulse of coherent light whose peak intensity ∝ N 2 . Such SF pulses have been observed in atomic and molecular gases, and their intriguing quantum nature has been unambiguously demonstrated. In this review, we focus on the rapidly developing field of research on SR phenomena in solids, where not only photon-mediated coupling (as in atoms) but also strong Coulomb interactions and ultrafast scattering processes exist. We describe SR and SF in molecular centers in solids, molecular aggregates and crystals, quantum dots, and quantum wells. In particular, we will summarize a series of studies we have recently performed on semiconductor quantum wells in the presence of a strong magnetic field. In one type of experiment, electron-hole pairs were incoherently prepared, but a macroscopic polarization spontaneously emerged and cooperatively decayed, emitting an intense SF burst. In another type of experiment, we observed the SR decay of coherent cyclotron resonance of ultrahigh-mobility two-dimensional electron gases, leading to a decay rate that is proportional to the electron density. These results show that cooperative effects in solid-state systems are not merely small corrections that require exotic conditions to be observed; rather, they can dominate the nonequilibrium dynamics and light emission processes of the entire system of interacting electrons.

“…31 The interaction with surface plasmons has been also employed to control certain properties of quantum emitters, including the decay rate, 32 angular directionality, 33 and energy transfer. 34,35 Single plasmon generation 36,37 and detection 38,39 have been experimentally demonstrated, and the achievements on plasmon transport switching 40 and plasmon-assisted qubit-qubit interaction, 41 suggest the on-chip implementation of quantum operations involving qubits in a plasmonic waveguide network. Along this line, we have recently explored the generation of entanglement between two qubits linked by a plasmonic waveguide (PW) consisting of a V-shaped channel milled in a flat metallic surface and operating in the optical regime 42,43 (see Fig.…”

We study the generation of entanglement between two distant qubits mediated by the surface plasmons of a metallic waveguide. We show that a V-shaped channel milled in a flat metallic surface is much more efficient for this purpose than a metallic cylinder. The role of the misalignments of the dipole moments of the qubits, an aspect of great importance for experimental implementations, is also studied. A careful analysis of the quantum dynamics of the system by means of a master equation shows that two-qubit entanglement generation is essentially due to the dissipative part of the effective qubit-qubit coupling provided by the surface plasmons. The influence of a coherent external pumping, needed to achieve a steady-state entanglement, is discussed. Finally, we pay attention to the question of how to get information experimentally on the degree of entanglement achieved in the system.

“…The superradiance has been an active field in atomic physics for decades [25][26][27]. Recently, it has also been studied in classical optics in the context of electromagnetically induced transparency [28,29], Fano interference [30][31][32] and in complex radiation environments [33][34][35][36]. The analog of superradiance has never been considered to be present in thermal emitters, which is vaguely justified since the underlying process of thermal radiation is an incoherent process.…”
