• Title: Rabi oscillations of bound states in the continuum
• Authors: Stefano Longhi
• Abstract summary: Photonic bound states in the continuum (BICs) are special localized and non-decaying states of a photonic system with a frequency embedded into the spectrum of scattered states. Here we consider such a simple photonic structure and show that, breaking mirror symmetry and allowing for non-nearest neighbor couplings, a doublet of quasi-BIC states can be sustained.

• Abstract: Photonic bound states in the continuum (BICs) are special localized and non-decaying states of a photonic system with a frequency embedded into the spectrum of scattered states. The simplest photonic structure displaying a single BIC is provided by two waveguides side-coupled to a common waveguide lattice, where the BIC is protected by symmetry. Here we consider such a simple photonic structure and show that, breaking mirror symmetry and allowing for non-nearest neighbor couplings, a doublet of quasi-BIC states can be sustained, enabling weakly-damped embedded Rabi oscillations of photons between the waveguides.

• Bound states in the continuum induced via local symmetries in complex structures [0.0]
  Bound states in the continuum (BICs) defy conventional wisdom that assumes a spectral separation between propagating waves, that carry energy away, and spatially localized waves corresponding to discrete frequencies. We introduce theoretically BICs relying on a different mechanism, namely local symmetries that enforce a field concentration on a part of a complex system without implying any global symmetry. Our alternative for achieving BICs in complex wave systems may be useful for applications like sensing, lasing, and enhancement of nonlinear interactions that require high-$Q$ modes.

• Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation [49.1574468325115]
  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

  We perform exact calculations for the oscillating BICs in a 1D photonic lattice coupled to "giant atom" at multiple points. We show that the bound states outside the energy band are detrimental to the oscillating BIC phenomenon. Our work can be experimentally implemented on current photonic waveguide array platforms.

  We use intuition to predict the formation of non-trivial photonic steady-states in one and two dimensions. We show that subradiant emitter configurations are linked to the emergence of steady-state light-localization in the driven-dissipative setting. These results shed light on the recently reported optically-defined cavities in polaritonic lattices.

• Dispersive bands of bound states in the continuum [0.0]
  Bound states in the continuum (BICs) have provided a new paradigm in optics and photonics, especially at the nanoscale. We introduce the idea of a crystal made of BICs, in which an array of BICs are indirectly coupled via a common continuum of states. Results are illustrated for a chain of optical cavities side-coupled to a coupled-resonator optical waveguide.

• Interference traps waves in open system: Bound states in the continuum [0.0]
  I review the four mechanisms of bound states in the continuum (BICs) in application to microwave and acoustic cavities open to directional waveguides. The most simple are the symmetry protected BICs which are localized inside the cavity. The most general and interesting is the Friedrich-Wintgen mechanism when the BICs are result of full destructive interference of outgoing resonant modes.

• Waveguide quantum optomechanics: parity-time phase transitions in ultrastrong coupling regime [125.99533416395765]
  We show that the simplest set-up of two qubits, harmonically trapped over an optical waveguide, enables the ultrastrong coupling regime of the quantum optomechanical interaction. The combination of the inherent open nature of the system and the strong optomechanical coupling leads to emerging parity-time (PT) symmetry. The $mathcalPT$ phase transition drives long-living subradiant states, observable in the state-of-the-art waveguide QED setups.
