The natural existence of crystalline symmetry in real materials manifests the importance of understanding crystalline symmetry-protected topological phases, especially for interacting systems. In this paper, we systematically construct and classify all the point-group crystalline topological superconductors and insulators in three-dimensional (3D) interacting fermion systems using the novel concept of a topological crystal. The corresponding higher-order topological surface theory can also be systematically studied via higher-order bulk-boundary correspondence. In particular, we discover several intrinsically interacting topological phases that cannot be realized in any free-fermion systems. Moreover, the crystalline equivalence principle for 3D interacting fermionic systems is also verified, with an additional subtle “twist” on the spin of fermions.

Coherent Structure Interactions in Spatially Extended Systems Driven by Excited Hidden Modes 受激励隐藏模驱动的空间扩展系统的相干结构相互作用

We study the emergence of strong interactions between dissipative coherent structures (pulses) in spatially extended systems. Focusing first on a prototypical model problem from fluid dynamics, that of liquid film flowing down a vertical plane, we show that under certain conditions, a two-pulse system undergoes a transition from a regime of decaying oscillatory dynamics to one with self-sustained oscillations. Intriguingly, such a transition is not governed by the standard Hopf bifurcation. Instead, a novel governing mechanism for transition to oscillatory dynamics is unraveled via a peculiar and atypical Hopf bifurcation in which a complex-conjugate resonance pair crosses the imaginary axis in the complex plane. Prior to crossing the essential spectrum (including at the bifurcation point), this resonance pair does not appear in the standard LC2-based spectral analysis but reveals itself when appropriate weighted functional spaces are used. We show that such a resonance pair originates from the splitting of a resonance pole of the single-pulse system. While this object is not part of the classical spectrum, it plays a vital role in shaping the system’s dynamics. We further demonstrate that this resonance-pole mechanism extends to a broad range of systems. Specifically, in the generalised Kuramoto-Sivashinsky equation—a model prototype applicable across a wide range of fields from fluid dynamics to geophysics and plasma physics—we observe the same bifurcation and resulting oscillatory pulse interactions. By contrast, in the FitzHugh-Nagumo model—a central model prototype in reaction-diffusion systems—the resonance pole splits into real eigenvalues, and monotonic pulse interactions occur. In addition, we illustrate that the resonance pole may induce oscillatory interactions in three-pulse systems and eventually lead to chaotic dynamics in strongly interacting multipulse systems, which can be quantified in terms of a positive Lyapunov exponent.

我们研究了空间扩展系统中耗散相干结构(脉冲)之间强相互作用的出现。首先关注流体动力学中的一个原型模型问题,即液膜沿垂直平面向下流动的问题,我们证明了在某些条件下,双脉冲系统经历了从衰减振荡动力学到自持续振荡动力学的过渡。有趣的是,这种转变不受标准Hopf分岔的支配。相反,一个新的控制机制过渡到振荡动力学是通过一个特殊的和非典型的Hopf分岔,其中一个复共轭共振对穿过虚轴在复平面。在越过基本光谱之前(包括在分岔点),该共振对不会出现在标准的基于lc2的光谱分析中,但当使用适当的加权泛函空间时,它会显示出来。我们证明了这种共振对起源于单脉冲系统的共振极的分裂。虽然这个物体不是经典光谱的一部分,但它在形成系统动力学方面起着至关重要的作用。我们进一步证明,这种共振极点机制扩展到广泛的系统。具体地说,在广义的Kuramoto-Sivashinsky方程(一个适用于从流体动力学到地球物理学和等离子体物理学等广泛领域的模型原型)中,我们观察到相同的分岔和由此产生的振荡脉冲相互作用。相反,在FitzHugh-Nagumo模型(反应扩散系统的中心模型原型)中,共振极分裂成实特征值,单调脉冲相互作用发生。此外,我们还说明了共振极可能在三脉冲系统中引起振荡相互作用,并最终导致强相互作用的多脉冲系统中的混沌动力学,这可以用正李雅普诺夫指数来量化。2025年由美国物理学会出版

Noninvertible Peccei-Quinn Symmetry and the Massless Quark Solution to the Strong CP Problem 不可逆Peccei-Quinn对称和强CP问题的无质量夸克解

We consider theories of gauged quark flavor and identify noninvertible Peccei-Quinn symmetries arising from fractional instantons when the resulting gauge group has nontrivial global structure. Such symmetries exist solely because the standard model has the same number of generations as colors, Ng=Nc, which leads to a massless down-type quark solution to the strong CP problem in an ultraviolet SU(9) theory of quark color-flavor unification. We show how the Cabibbo-Kobayashi-Maskawa flavor structure and weak CP violation can be generated without upsetting our solution. Published by the American Physical Society 2025

Multipolar Anisotropy in Anomalous Hall Effect from Spin-Group Symmetry Breaking 自旋群对称破缺中反常霍尔效应的多极各向异性

The traditional view of the anomalous Hall effect (AHE) in ferromagnets is that it arises from the magnetization perpendicular to the measurement plane and that there is a linear dependence on the latter. Underlying such a view is the thinking that the AHE is a time-reversal symmetry breaking phenomenon and can therefore be treated in terms of a power series in the magnetic order. However, this view is squarely challenged by a number of recent experiments, urging for a thorough theoretical investigation on the fundamental level. We find that for strong magnets, it is more appropriate and fruitful to regard the AHE as a spin-group symmetry breaking phenomenon where the critical parameter is the spin-orbit interaction strength, which involves a much smaller energy scale. In collinear ferromagnets, the spin-orbit coupling breaks the ∞2′ spin rotation symmetry, and the key to characterizing such symmetry breaking is the identification of spin-orbit vectors which transform regularly under spin-group operations. Born out of our framework is a rich multipolar relationship between the anomalous Hall conductivity and the magnetization direction, with each pole being expanded progressively in powers of the spin-orbit coupling strength. For the leading order contribution, i.e., the dipole, its isotropic part corresponds to the traditional view, and its anisotropic part can lead to the in-plane AHE where the magnetization lies within the measurement plane. Beyond the dipolar structure, the octupolar structure offers the leading order source of nonlinearity and hence introduces unique anisotropy where the dipolar structure cannot. Our theory thus offers a unified explanation for the in-plane AHE recently observed in various ferromagnets, and further extends the candidate material systems. It can also be generalized to study the anomalous Hall effect in crystals with any periodic spin structure and to study the nonlinear Hall effect and the spin Hall effect. Our theory lays the ground for decoding the coupling between various transport and optical phenomena and the magnetic orders. Published by the American Physical Society 2025
关于铁磁体中反常霍尔效应的传统观点认为,反常霍尔效应是由垂直于测量平面的磁化引起的,并且与测量平面的磁化呈线性关系。这种观点的基础是认为AHE是一种时间反转对称性破缺现象,因此可以用磁序的幂级数来处理。然而,这一观点受到了最近一些实验的直接挑战,迫切需要在基本层面上进行彻底的理论研究。我们发现,对于强磁体,将AHE视为一种自旋-群对称破缺现象更为合适和有效,其关键参数是自旋-轨道相互作用强度,涉及的能量尺度要小得多。在共线铁磁体中,自旋轨道耦合破坏了∞2’自旋旋转对称性,表征这种对称性破坏的关键是识别自旋群操作下有规则变换的自旋轨道向量。从我们的框架中诞生了异常霍尔电导率与磁化方向之间丰富的多极关系,每个极点在自旋轨道耦合强度的幂次上逐步扩展。对于阶贡献即偶极子,其各向同性部分符合传统观点,其各向异性部分可导致磁化位于测量平面内的面内AHE。除了偶极结构之外,八极结构提供了非线性的主要来源,因此引入了偶极结构所不能的独特的各向异性。因此,我们的理论为最近在各种铁磁体中观察到的面内AHE提供了统一的解释,并进一步扩展了候选材料体系。它也可以推广到研究任意周期自旋结构晶体中的反常霍尔效应,以及研究非线性霍尔效应和自旋霍尔效应。我们的理论为解码各种输运和光现象与磁序之间的耦合奠定了基础。2025年由美国物理学会出版

Arrays of coupled superconducting qubits are analog quantum simulators able to emulate a wide range of tight-binding models in parameter regimes that are difficult to access or adjust in natural materials. In this work, we use a superconducting qubit array to emulate a tight-binding model on the rhombic lattice, which features flat bands. Enabled by broad adjustability of the dispersion of the energy bands and of on-site disorder, we examine regimes where flat-band localization and Anderson localization compete. We observe disorder-induced localization for dispersive bands and disorder-induced delocalization for flat bands. Remarkably, we find a sudden transition between the two regimes and, in its vicinity, the semblance of quantum critical scaling. Published by the American Physical Society 2025

We introduce homological measurement, a framework for measuring the logical Pauli operators encoded in Calderbank-Shor-Steane stabilizer codes. The framework is based on the algebraic description of such codes as chain complexes. Protocols such as lattice surgery and some of its recent generalizations are shown to be special cases of homological measurement. Using this framework, we develop a specific protocol called edge expanded homological measurement for fault-tolerant measurement of arbitrary logical Pauli operators of general quantum low density parity-check codes, requiring a number of ancillary qubits growing only linearly with the weight of the logical operator measured, and guarantee that the distance of the code is preserved. We further benchmark our protocol numerically in a photonic architecture based on Gottesman-Kitaev-Preskill qubits, showing that the logical error rates of various codes are on par with other methods requiring more ancilla qubits.

介绍了一种测量编码在calderbank - shorr - steane稳定码中的逻辑泡利算子的框架——同调测量。该框架基于链配合物等代码的代数描述。晶格手术等方案及其最近的一些推广被证明是同调测量的特殊情况。在此框架下,我们开发了一种称为边缘扩展同调测量的特定协议,用于一般量子低密度奇偶校验码的任意逻辑泡利算子的容错测量,该协议要求辅助量子比特的数量仅随所测量逻辑算子的权重线性增长,并保证码的距离保持不变。我们进一步在基于Gottesman-Kitaev-Preskill量子比特的光子架构中对我们的协议进行数值基准测试,表明各种代码的逻辑错误率与其他需要更多辅助量子比特的方法相当。2025年由美国物理学会出版
