“…In semiconductor implementations, uses of the first type have been demonstrated: single natural and artificial atomic systems have been coherently driven by SAWs with evidence of phonon-dressed atomic states [46] and phonon-assisted dark states (see section 4) being reported, as well as the modulation of energy levels of quantum dots [7]. Moreover, SAWs have been used to provide moving potential wells for semiconductor quasiparticles as a route towards quantum channels for single electrons (see section 3) and the study of many-body quantum ground states of an exciton-polariton condensate in SAW-induced lattices [47].…”

Today, surface acoustic waves (SAWs) and bulk acoustic waves are already two of the very few phononic technologies of industrial relevance and can been found in a myriad of devices employing these nanoscale earthquakes on a chip. Acoustic radio frequency filters, for instance, are integral parts of wireless devices. SAWs in particular find applications in life sciences and microfluidics for sensing and mixing of tiny amounts of liquids. In addition to this continuously growing number of applications, SAWs are ideally suited to probe and control elementary excitations in condensed matter at the limit of single quantum excitations. Even collective excitations, classical or quantum are nowadays coherently interfaced by SAWs. This wide, highly diverse, interdisciplinary and continuously expanding spectrum literally unites advanced sensing and manipulation applications. Remarkably, SAW technology is inherently multiscale and spans from single atomic or nanoscopic units up even to the millimeter scale. The aim of this Roadmap is to present a snapshot of the present state of surface acoustic wave science and technology in 2019 and provide an opinion on the challenges and opportunities that the future holds from a group of renown experts, covering the interdisciplinary key areas, ranging from fundamental quantum effects to practical applications of acoustic devices in life science.

“…They provide localised modes isolated in energy from the photonic bands. Their properties can eventually be tailored to create, for instance, localised lasing modes [5,24], or used as precursors of lattice solitons [25][26][27][28][29]. A method to create isolated gap states is to implement one-dimensional lattices with nontrivial topology.…”

We report polariton lasing in localised gap states in a honeycomb lattice of coupled micropillars. Localisation of the modes is induced by the optical potential created by the excitation beam, requiring no additional engineering of the otherwise homogeneous polariton lattice. The spatial shape of the gap states arises from the interplay of the orbital angular momentum eigenmodes of the cylindrical potential created by the excitation beam and the hexagonal symmetry of the underlying lattice. Our results provide insights into the engineering of defect states in two-dimensional lattices.

“…Exciton polaritons (polaritons) in semiconductor microcavities [3][4][5] possess substantially smaller effective masses and can condense not only at liquid Helium [6][7][8] but also up to the room temperature [9,10]. This makes a system of polaritons in artificial periodic potentials an excellent alternative platform for studying manybody physics, gap solitons [11,12], topological polariton states [13,14], as well as classical [15] and quantum [16] simulators.…”
