“…To introduce a detuning parameter [73,74], one can couple WGs with different widths w 1 along the y-axis [see Fig. 2(a)] [18]. For mimicking multipulse couplings with the pulses being of different phases, one can divide the coupled WGs into several coupling parts along x-axis, and adjacent parts are connected by phase shifters [60] to adjust the phase difference between sound waves, which corresponds to the phase difference between different pairs of pulses [75].…”

“…There are also achievements connecting classical waves to topological and quantum effects [4,6,[17][18][19][20][21][22], which may not only provide broader platforms for expanding categories of acoustic metamaterials but may also open up a new avenue for the construction of functional metamaterials using previously unexplored approaches. We intend to build a bridge between unidirectional acoustic metamaterials (UDAMs) and quantum computation.…”

Nonadiabatic holonomic quantum transformations (NHQTs) have attracted wide attention and have been applied in many aspects of quantum computation, whereas related research is usually limited to the field of quantum physics. Here we bring NHQTs into constructing a unidirectional acoustic metamaterial (UDAM) for shaping classical beams. The UDAM is made up of an array of three-waveguide couplers, where the propagation of acoustic waves mimics the evolution of NHQTs. The excellent agreement among analytical predictions, numerical simulations, and experimental measurements confirms the great applicability of NHQTs in acoustic metamaterial engineering. The present work extends research on NHQTs from quantum physics to the field of classical waves for designing metamaterials with simple structures and may pave a new way to design UDAMs that would be of potential applications in acoustic isolation, communication, and stealth.

“…By performing quantum-classical analogs, the technique of AP has been applied to classical physics as well, showing surprising merits for designing optical devices with attractive functions, such as, to name a few, optical polarization control [7], frequency conversion [8], and energy transfer [9][10][11][12][13][14][15][16]. Despite numerous achievements in optics, the applications of AP in acoustics have not been widely reported so far [17][18][19][20], especially its ability to obtain arbitrary beam splitting in waveguide (WG) couplers.…”

In this work, we introduce quantum-mechanical adiabatic passage (AP) into the design of spatial acoustic four-waveguide (WG) couplers. Thanks to the agreement in form between the Schrödinger equation in quantum mechanics and the coupled-mode equation of classical wave, the behavior of propagating wave in coupled WGs is capable of mapping to quantum states driven by external fields. By coupling the input and output WGs with a mediator WG in space, an apparent beam splitting is realized and the ratio of intensity can be customized arbitrarily by altering the space-dependent coupling strengths. Moreover, a one-way propagation feature is exhibited in the spatial coupler when an appropriate loss is introduced in the mediator WG owing to the existence of dark state. This work builds a bridge between quantum adiabatic technology and acoustic beam splitter, which may have potential applications in acoustic communication, filtering and detection.

“…Besides, the performance of device is subject to the narrow band and single function, hindering practicability and industrialization of acoustic coupler. In the past decade, the combination of acoustic systems with other concepts (such as topological state [59][60][61][62][63][64], parity-time symmetry [65][66][67][68], quantum adiabaticity [69][70][71][72] and Landau-Zener transition [73]) has received great interest and has led to surprising advantages for designing advanced functional acoustic metadevices. As a promising and pragmatic quantum technology, yet STAP in an acoustic system has not been reported so far.…”

Shortcut to adiabatic passage (STAP), initially proposed to accelerate adiabatic quantum state transfer, has been widely explored and applied in quantum optics and integrated optics. Here we bring STAP into the field of acoustics to design compact couplers and functional metamaterial. The space-varying coupling strengths of acoustic waveguides (WGs) are tailored by means of dressed states in a three-level system, accounting for the desirable acoustic energy transfer among three WGs with short length. We show that the acoustic coupler has one-way feature when loss is introduced into the intermediate WG. More uniquely, when the propagation of acoustic wave is designed to mimic a Hadamard transformation, an acoustic metamaterial can be constructed by arraying several couplers, possessing the beam-splitting function and unidirectional, broadband performances. Our work bridges STAP and the acoustic coupler as well as metamaterial, which may have profound impacts on exploring quantum technologies for promoting advanced acoustic devices.
