“…The bichromatic excitation of quantum systems with PDMs has been studied in a wide range of quantum systems, including electron and nuclear spins [50,51], QDs [52,53], and superconducting qubits [54]. The RFS of an asymmetric QD has been recently analyzed in the regime of dissipative dynamics and weak frequency modulation of the low-frequency (LF) field [55,56].…”

A two-level quantum emitter with broken inversion symmetry simultaneously driven by an optical field and a microwave field that couples to the permanent dipole's moment is presented. We focus to a situation where the angular frequency of the microwave field is chosen such that it closely matches the Rabi frequency of the optical field, the so-called Rabi resonance condition. Using a series of unitary transformations we obtain an effective Hamiltonian in the double-dressed basis which results in easily solvable Bloch equations which allow us to derive analytical expressions for the spectrum of the scattered photons. We analyze the steady-state population inversion of the system which shows a distinctive behavior at the Rabi resonance with regard to an ordinary two-level nonpolar system. We show that saturation can be produced even in the case that the optical field is far detuned from the transition frequency, and we demonstrate that this behavior can be controlled through the intensity and the angular frequency of the microwave field. The spectral properties of the scattered photons are analyzed and manifest the emergence of a series of Mollow-like triplets which may be spectrally broadened or narrowed for proper values of the amplitude and/or frequency of the low-frequency field. We also analyze the phase-dependent spectrum which reveals that a significant enhancement or suppression of the squeezing at certain sidebands can be produced. These quantum phenomena are illustrated in a recently synthesized molecular complex with high nonlinear optical response although they can also occur in other quantum systems with broken inversion symmetry.

“…As is well-known, for a sufficiently strong monochromatic field, the spectrum has a symmetric three-peak structure, known as the Mollow triplet [1]. More recently, the bi-and multi-chromatically driven quantum systems are of interest [25][26][27][28]. In such systems, the spectrum turns out to have a complicated multipeak structure [7][8][9][10][11][12][13], which can be either symmetric or asymmetric.…”

We study the origin of the symmetry of the fluorescence spectrum from the two-level system subjected to a low-frequency periodic modulation and a near-resonant high-frequency monochromatic excitation by using the analytical and numerical methods based on the Floquet theory. We find that the fundamental origin of symmetry of the spectrum can be attributed to the presence of the generalized parity of the Floquet states, which depends on the driving parameters. The absence of the generalized parity can lead to the asymmetry of the spectrum. Based on the generalized parity, the conditions for the symmetry and asymmetry of the spectrum can be derived, which succeeds in predicting symmetry and asymmetry of the spectrum for the harmonic, biharmonic, and multiharmonic modulations. Moreover, we find that the secular approximation widely used in the analytical calculation may lead to artifact symmetry of the spectrum that vanishes when such approximation is avoided. The present study provides a significant perspective on the origin of the symmetry of the spectrum.

When interaction between light and matter is in the strong coupling region, matter has a significant influence on the whole system, with potential to develop low-power active optical devices. Strong coupling can verify some basic problems of quantum physics, and it is an ideal system to study light-matter interaction, providing an intuitive and accurate demonstration of some pure quantum effects with small mass and easy optical control. Here, the most important advances in strong coupling in recent years are described. Of late, an extensive series of experimental and theoretical findings, and remarkable achievements have been made in this field. Strong coupling between cavities and some new materials such as semiconductors, two-dimensional (2D) material, and quantum dots (QDs) are the focus of research in this field. Another field that has made outstanding progress is the application of this optical phenomenon, including resonance-enhanced Raman and infrared spectra, nanolasers, and cavity-enhanced sensing. Furthermore, the potential in this field arises for future quantum information and quantum optical devices. It is now developing at a very fast rate and can be predicted to have broad prospects for development in the future. Some prospects in terms of design and application are included.
