“…One notices that dissipative coupling γ only leads to frequency shifts ω p if the coherent coupling g is nonzero, while the coherent coupling g only modifies the collective damping rates γ p if the dissipative coupling γ is nonzero, due to the form of Eq. (42). Furthermore, the complex frequency of Eq.…”

We study a prototypical model of two coupled two-level systems, where the competition between coherent and dissipative coupling gives rise to a rich phenomenology. In particular, we analyze the case of asymmetric coupling, as well as the limiting case of chiral (or one-way) coupling. We investigate various quantum optical properties of the system, including its steady-state populations, power spectrum, and second-order correlation functions, and outline the characteristic features which emerge in each quantity as one sweeps through the nontrivial landscape of effective complex couplings. Most importantly, we reveal instances of population trapping, unexpected spectral features, and strong emission correlations.

“…As such, one may use cascaded theory to posit a well-defined criterion for chiral coupling [28,36,40]. Meanwhile, a number of papers have appeared recently successfully employing the cascaded formalism to uncover nontrivial photon correlations [41][42][43][44].…”

“…Indeed, the Jaynes–Cummings model shows that these(non‐classical) states can be generated using non‐classical sources (thermal or laser light are considered classical while one or several photon sources are considered quantum). The study of the excitation polaritons by these sources are under progress (see,e.g., this theoretical study of the coupled harmonic oscillator as well as of the coupled two‐level system ). Polaritons can also encode the orbital angular momentum of light and can control of the spin–orbit states for quantum information applications …”

Strong Light–Matter Coupling as a New Tool for Molecular and Material Engineering: Quantum Approach

When atoms come together and bond, these new states are called molecules and their properties determine many aspects of our daily life. Strangely enough, it is conceivable for light and molecules to bond, creating new hybrid light–matter states with far‐reaching consequences for these strongly coupled materials. Even stranger, there is no “real” light needed to obtain the effects; it simply appears from the vacuum, creating “something from nothing.” Surprisingly, the setup required to create these materials has become moderately straightforward. In its simplest form, one only needs to put a strongly absorbing material at the appropriate place between two mirrors, and quantum magic can appear. Only recently has it been discovered that strong coupling can affect a host of significant effects at a material and molecular level, which were thought to be independent of the “light” environment: phase transitions, conductivity, chemical reactions, etc. This review addresses the fundamentals of this opportunity: the quantum mechanical foundations, the relevant plasmonic and photonic structures, and a description of the various applications, connecting material chemistry with quantum information, entanglement, nonlinear optics, and chemical reactivity. Ultimately, revealing the interplay between light and matter in this new regime opens attractive avenues for various new technologies.

“…Only recently has it been proposed that entangled photons can be exploited as a useful spectroscopic probe of atomic and molecular processes. [11][12][13][14][15][16] The spectral and temporal nature of entangled photons offer a unique means for interrogating the dynamics and interactions between molecular states. The crucial consideration is that when entangled photons are created, typically by spontaneous parametric down-conversion, there is a precise relation between the frequency and wavevectors of the entangled pair.…”

We present an input/output analysis of photon-correlation experiments whereby a quantum mechanically entangled bi-photon state interacts with a material sample placed in one arm of a Hong-Ou-Mandel (HOM) apparatus. We show that the output signal contains detailed information about subsequent entanglement with the microscopic quantum states in the sample. In particular, we apply the method to an ensemble of emitters interacting with a common photon mode within the open-system Dicke Model. Our results indicate considerable dynamical information concerning spontaneous symmetry breaking can be revealed with such an experimental system. arXiv:1707.03304v1 [quant-ph]
