“…Although the vast majority of systems exhibiting SR involve electronic transitions at optical frequencies, SR has also been observed in spin systems . Spin SR has attracted much attention due to its many possible applications to sensing and spin masers (microwave amplification by stimulated emission of radiation). − Measuring the delay time of a superradiant burst provides an accurate evaluation of the triggering intensity because the delay time depends exponentially on the intensity of the external pulse and spin SR can be triggered by extremely weak external pulses. Thus, systems exhibiting spin SR can be used to produce sensitive detectors.…”

There is increasing interest in the study of chiral degrees of freedom occurring in matter and in electromagnetic fields. Opportunities in quantum sciences will likely exploit two main areas that are the focus of this Review: (1) recent observations of the chiral-induced spin selectivity (CISS) effect in chiral molecules and engineered nanomaterials and (2) rapidly evolving nanophotonic strategies designed to amplify chiral light–matter interactions. On the one hand, the CISS effect underpins the observation that charge transport through nanoscopic chiral structures favors a particular electronic spin orientation, resulting in large room-temperature spin polarizations. Observations of the CISS effect suggest opportunities for spin control and for the design and fabrication of room-temperature quantum devices from the bottom up, with atomic-scale precision and molecular modularity. On the other hand, chiral–optical effects that depend on both spin- and orbital-angular momentum of photons could offer key advantages in all-optical and quantum information technologies. In particular, amplification of these chiral light–matter interactions using rationally designed plasmonic and dielectric nanomaterials provide approaches to manipulate light intensity, polarization, and phase in confined nanoscale geometries. Any technology that relies on optimal charge transport, or optical control and readout, including quantum devices for logic, sensing, and storage, may benefit from chiral quantum properties. These properties can be theoretically and experimentally investigated from a quantum information perspective, which has not yet been fully developed. There are uncharted implications for the quantum sciences once chiral couplings can be engineered to control the storage, transduction, and manipulation of quantum information. This forward-looking Review provides a survey of the experimental and theoretical fundamentals of chiral-influenced quantum effects and presents a vision for their possible future roles in enabling room-temperature quantum technologies.

“…This phenomenon should not be confused with spin induction or maser generation, as is explained in reviews [1,7]. For instance, when the spin motion is pushed by a strong transverse field, one has spin induction, which, though being a coherent process, has nothing to do with superradiance.…”

“…Spin superradiance is a phenomenon that got its name because of its close analogy with superradiance occurring in atomic systems [1]. In the latter, superradiance was predicted by Dicke [2] in 1954 and nowadays it is well studied both theoretically and experimentally, being now a part of textbooks [3,4].…”

Spin superradiance is a relatively novel notion, being discovered experimentally [5,6] in 1988, and whose exhaustive microscopic theory has been elaborated only recently (see reviews [1,7]).…”

“…This is certainly impermissible, since without a precise fixed terminology any scientific descriptions and discussions become pointless. Therefore in the present paper the notion of superradiance is used in its strictly defined and commonly accepted sense, be it atomic [2][3][4] or spin [1,7] superradiance: Superradiance is a self-organized collective emission of electromagnetic radiation.…”

A comparative analysis is given of spin superradiance and atomic superradiance. Their similarities and distinctions are emphasized. It is shown that, despite a close analogy, these phenomena are fundamentally different. In atomic systems, superradiance is a self-organized process, in which both the initial cause, being spontaneous emission, as well as the collectivizing mechanism of their interactions through the common radiation field, are of the same physical nature. Contrary to this, in actual spin systems with dipole interactions, the latter are the major reason for spin motion. Electromagnetic spin interactions through radiation are negligible and can never produce collective effects. The possibility of realizing superradiance in molecular magnets by coupling them to a resonant circuit is discussed.Comment: Latex file, 12 pages, no figure
