From detailed numerical calculations, we demonstrate that in simple photonic crystal structures, a discrete number of Bloch surface-localized eigenstates can exist inside the continuum of free-space modes. Coupling to the free space causes the surface modes to leak, but the forward and back-reflected leakage may interfere destructively to create a perfectly bound surface state with zero leakage. We perform analytical temporal coupled-mode theory analysis to show the generality of such phenomenon and its robustness from variations of system parameters. Periodicity, time-reversal invariance, two-fold rotational symmetry and a perfectly reflecting boundary are necessary for these unique states.

“…The sample is repatterned to open large squares around the pyramid. The squares must be sufficiently large to accommodate a photonic crystal cavity of sufficient size so that the Q-value is limited by vertical losses, typically 10 rings of holes [100]. A second patterned-substrate growth planarizes the pyramids through selective InP growth in these large openings.…”

Strong confinement of charges in few electron systems such as in atoms, molecules and quantum dots leads to a spectrum of discrete energy levels that are often shared by several degenerate quantum states. Since the electronic structure is key to understanding their chemical properties, methods that probe these energy levels in situ are important. We show how electrostatic force detection using atomic force microscopy reveals the electronic structure of individual and coupled self-assembled quantum dots. An electron addition spectrum in the Coulomb blockade regime, resulting from a change in cantilever resonance frequency and dissipation during tunneling events, shows one by one electron charging of a dot. The spectra show clear level degeneracies in isolated quantum dots, supported by the first observation of predicted temperature-dependent shifts of Coulomb blockade peaks. Further, by scanning the surface we observe that several quantum dots may reside on what topologically appears to be just one. These images of grouped weakly and strongly coupled dots allow us to estimate their relative coupling strengths.

“…Encouragingly, cavities with the required properties can be realized in certain high-g microcavities with current micro-manufacturing and micro-etching technologies (see reference 29 and references therein). For example, in toroidal microcavities, the cooperativity factor of C ∼ 10 7 was achieved experimentally 29 , and in the photonic band gap cavities, C ∼ 10 3 was also realized 25,27,30 . In order to achieve the honeycomb lattice, one can build three optical cavities in different directions at each site of the lattice, or design an appropriate structure of the photonic band gap cavities to restrict the photons of different frequencies in three directions.…”

Kitaev model has both Abelian and non-Abelian anyonic excitations. It can act as a starting point for topological quantum computation. However, this model Hamiltonian is difficult to implement in natural condensed matter systems. Here we propose a quantum simulation scheme by constructing the Kitaev model Hamiltonian in a lattice of coupled cavities with embedded Λ-type three-level atoms. In this scheme, several parameters are tunable, for example, via external laser fields. Importantly, our scheme is based on currently existing technologies and it provides a feasible way of realizing the Kitaev model to explore topological excitations.
