The pith

Concatenating superlattices with alternating topology creates tunable coupled phonon interface states.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper shows that alternating the topology of superlattices produces localized phonon states at their interfaces. Concatenating three such superlattices couples two interface states, which then hybridize into symmetric and antisymmetric modes whose frequency splitting is adjusted by the reflectivity of the central layer. This splitting reaches tens of gigahertz and the approach extends to longer chains that form narrow minibands while staying localized. The behavior is confirmed through experiments on grown GaAs/AlAs samples using pump-probe measurements together with transfer-matrix models. A reader would care because it supplies a route to build interacting phonon modes in the gigahertz range that draw on topological protection.

Core claim

By concatenating three superlattices with alternating topology, we realize two coupled interface states that hybridize into symmetric and antisymmetric modes, whose splitting can be tuned over tens of gigahertz by varying the reflectivity of the central DBR. Extending this concept, we engineer chains of up to N=6 coupled interface states that form narrow topological minibands while remaining strongly localized at the interfaces. These states are observed in molecular-beam-epitaxy-grown GaAs/AlAs heterostructures using time-domain pump-probe transient reflectivity measurements and reproduced by transfer-matrix calculations and a simple analytical model.

What carries the argument

Hybridization of topological interface states through a central tunable distributed Bragg reflector that controls the coupling strength between states formed by alternating Zak phases.

Load-bearing premise

The interface states remain strongly localized and their hybridization is dominated by the topological band inversion and central DBR reflectivity without significant effects from fabrication disorder, interface roughness, or non-topological scattering.

What would settle it

Measuring that the observed frequency splitting stays fixed when the central DBR reflectivity is changed, or finding that the states delocalize in samples with only minor roughness, would show the central claim is not correct.

Topological interface states in one-dimensional superlattices provide spatially localized phonon modes protected by the topology of the underlying band structure. In GaAs/AlAs distributed Bragg reflectors (DBRs), such states can be engineered through band inversion between superlattices with opposite Zak phases within the Su-Schrieffer-Heeger (SSH) framework. Here, we demonstrate topological phonon molecules and extended chains formed by coupled nanophononic interface states. By concatenating three superlattices with alternating topology, we realize two coupled interface states that hybridize into symmetric and antisymmetric modes, whose splitting can be tuned over tens of gigahertz by varying the reflectivity of the central DBR. Extending this concept, we engineer chains of up to N=6 coupled interface states that form narrow topological minibands while remaining strongly localized at the interfaces. We experimentally observe these coupled states in molecular-beam-epitaxy-grown GaAs/AlAs heterostructures using time-domain pump-probe transient reflectivity measurements, and reproduce their behavior using transfer-matrix calculations and a simple analytical model for the mode splitting. These results establish topological interface states as a robust platform for engineering coupled phononic systems and tunable nanophononic architectures in the GHz regime.

Referee Report

2 major / 1 minor

Summary. The manuscript demonstrates coupled topological interface states in GaAs/AlAs superlattices by concatenating three structures with alternating Zak phases, realizing hybridization into symmetric and antisymmetric phonon modes whose GHz-scale splitting is tuned via central DBR reflectivity. It extends the concept to chains of up to N=6 states forming localized minibands, with experimental verification via time-domain pump-probe transient reflectivity on MBE-grown samples, supported by transfer-matrix calculations and an analytical splitting model.

Significance. If the central claim holds, the work provides a controllable platform for topological phonon molecules and minibands in the GHz regime, advancing nanophononics by linking band-inversion-protected interface states to tunable hybridization. The experimental-modeling combination (pump-probe data reproduced by transfer-matrix and analytics) strengthens the case for topological engineering of phononic architectures.

major comments (2)
  1. [Transfer-matrix modeling] Transfer-matrix modeling section: The calculations and analytical splitting formula treat interfaces as atomically abrupt with perfect periodicity. No quantitative comparison is made to models incorporating realistic MBE roughness (1-2 monolayer intermixing), which can produce non-topological scattering shifts and broadening comparable to the reported tens-of-GHz splitting, especially at reduced central DBR reflectivity. This leaves open whether the observed tuning is dominated by topological hybridization.
  2. [Experimental results] Experimental results and data analysis: The manuscript provides no details on error bars, data exclusion criteria, or quantitative fits (e.g., R² or chi-squared values) between measured and modeled mode splittings. This weakens verification of the claim that splitting is tunable over tens of GHz purely by DBR reflectivity.
minor comments (1)
  1. [Figures and captions] Figure captions and main text could clarify the exact phonon wavelengths relative to expected roughness correlation lengths to aid reader assessment of disorder effects.

  1. Referee: Transfer-matrix modeling section: The calculations and analytical splitting formula treat interfaces as atomically abrupt with perfect periodicity. No quantitative comparison is made to models incorporating realistic MBE roughness (1-2 monolayer intermixing), which can produce non-topological scattering shifts and broadening comparable to the reported tens-of-GHz splitting, especially at reduced central DBR reflectivity. This leaves open whether the observed tuning is dominated by topological hybridization.

    Authors: We agree that realistic MBE interface roughness merits explicit discussion, as 1-2 monolayer intermixing can in principle introduce non-topological scattering. However, the close quantitative match between our measured splittings and the ideal transfer-matrix predictions across the full range of central DBR reflectivities indicates that hybridization dominates. In the revised manuscript we will add a dedicated paragraph that estimates the magnitude of roughness-induced shifts using a simple perturbed transfer-matrix approach and shows that these contributions remain well below the observed tunable splitting (tens of GHz). revision: yes

  2. Referee: Experimental results and data analysis: The manuscript provides no details on error bars, data exclusion criteria, or quantitative fits (e.g., R² or chi-squared values) between measured and modeled mode splittings. This weakens verification of the claim that splitting is tunable over tens of GHz purely by DBR reflectivity.

    Authors: We will revise the experimental section to include error bars on all reported splitting values, a brief description of data-acquisition and exclusion criteria, and quantitative goodness-of-fit metrics (R² and reduced chi-squared) for the comparison between measured and modeled splittings versus central DBR reflectivity. These additions will be incorporated into both the main text and the supplementary information. revision: yes

No circularity: results rest on independent transfer-matrix modeling and experiment

full rationale

The paper's derivation chain begins from the standard SSH model for Zak-phase band inversion in GaAs/AlAs DBRs, proceeds to explicit transfer-matrix calculations that solve the wave equation for the layered structure with given layer thicknesses and acoustic impedances, and derives an analytical splitting formula from the resulting coupled-mode eigenvalues. These steps are not fitted to the target splitting data and then re-labeled as predictions; the transfer-matrix code is a direct numerical implementation of the wave equation without adjustable parameters tuned to the observed GHz splitting. Experimental pump-probe data serve as external validation rather than input to the model. No self-citation is invoked to establish uniqueness or to smuggle an ansatz; the SSH framework is cited as prior literature without author overlap in the load-bearing steps. The observed tuning with central DBR reflectivity follows directly from the reflectivity-dependent coupling strength in the transfer-matrix output, without reduction to a self-definitional loop.
