“…Such quantization triggers the appearance of topological surface states with an energy dispersion connecting two topologically inequivalent Weyl points: the Fermi arcs (13). These unconventional surface modes are responsible for exotic phenomena in electronic systems such as bulk-mediated quantum oscillations (14), as well as unusual classical wave propagation in bosonic settings such as photonics or acoustics (15)(16)(17)(18)(19). However, an important practical difference between the two scenarios is that whereas the electronic ground state fills up until the Fermi level and thus naturally probes Fermi arc energies, bosonic excitations accumulate in the lowest energy state because of their statistics.…”

Fermi arcs, i.e., surface states connecting topologically distinct Weyl points, represent a paradigmatic manifestation of the topological aspects of Weyl physics. We investigate a light-matter interface based on the photonic counterpart of these states and prove that it can lead to phenomena with no analog in other setups. First, we show how to image the Fermi arcs by studying the spontaneous decay of one or many emitters coupled to the system’s border. Second, we demonstrate that, exploiting the negative refraction of these modes, the Fermi arc surface states can act as a robust quantum link, enabling, e.g., the occurrence of perfect quantum state transfer between the considered emitters or the formation of highly entangled states. In addition to their fundamental interest, our findings evidence the potential offered by the photonic Fermi arc light-matter interfaces for the design of more robust quantum technologies.

“…This specially prepared beam that pulls is also referred to as the optical tractor beam in the literature [8][9][10][11][12][13][14][15]. It is typically realized in an open space [16][17][18][19][20][21][22][23][24][25][26][27], and sometimes, near a surface [28][29][30][31][32][33][34][35][36]. However, such pulling can only be achieved when the beam and particle are both carefully prepared in order to tailor the delicate light-matter interaction required by pulling.…”

Optical tractor beams capable of pulling particles backward have garnered significant and increasing interest. Generally, it is easier to push than to pull. Traditional optical tractor beams are limited to free space beams with fairly small forward wavevectors, enabling them to pull selected particles. In this study, we present a comprehensive theory for the optical force exerted by a surface wave (SW) through meticulous analytical and numerical calculations, uncovering the relationship between the canonical momentum and optical forces. Moreover, based on the theory, we demonstrate a general-purpose optical surface tractor beam (OSTB) that can pull virtually any passive particle, regardless of its size, composition, and geometry. The OSTB utilizes a SW with negative canonical momentum characterized by a single well-defined negative Bloch k. Unlike previous cases, it relies on a novel mechanism where the negative incident force always surpasses the recoil force. We demonstrate explicitly that the same OSTB, when excited on the surface of a double-negative-index metamaterial, can pull particles with varying morphologies.

“…Recently, there has been a surge of interest in topological physics. Besides abundant fundamental research [14][15][16][17][18][19][20][21][22], the characteristic of unidirectional boundary transport of topologically nontrivial surface states provides a robust route to the one-way waveguiding and inspires varies applications [23][24][25][26][27][28][29][30][31][32][33]. The chiral surface state [34,35] which is supported in quantum Hall systems is possibly the most fascinating one since its one-way transport is robust against almost all kinds of perturbations.…”

We propose the topological one-way waveguide for acoustic waves whose width can be flexibly adjusted. The waveguide is constructed by a heterostructure where an ordinary phononic crystal is sandwiched by two time-reversal-symmetry-broken (TRS-broken) phononic crystals with their cylinders spinning in an opposite manner. The waveguide mode is confined to the ordinary phononic crystal and exhibits the gap-less and asymmetric dispersion. Therefore, we can tune the width of the waveguide by adjusting the thickness of the ordinary phononic crystal, and the waveguide mode is one-way transport which is robust against various types of local disorders and arbitrary bends. Owing to these, this acoustic topological one-way waveguide can meet the requirements of more applications compared with conventional waveguides and conventional one-way waveguides based on chiral surface waves.
