It is demonstrated that the incorporation of a purely spatial Chern-Simons term, which violates parity, into the Landau-Ginzburg free energy leads to a complex magnetic penetration depth. This characteristic indicates that, aside from possessing an effective penetration depth, the magnetic field on the surface of the superconductor experiences periodic spatial oscillations, which significantly deviates from the conventional Meissner effect. In particular, it is observed that as the degree of parity breaking, quantified by the strength of the spatial Chern-Simons term, increases, a vortex solution with magnetic field inversion may emerge. With the discovery of superconductivity in certain Weyl semimetals, the possibility of experimentally observing this phenomenon in these materials is anticipated.</p>","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For data with at best quasi-labels, graphs are a natural representation and have important applications in many industries and scientific disciplines. Specifically, for unlabeled data, anomaly detection on graphs is a method to determine which data points do not posses the latent characteristics that are present in most other data. There have been a variety of classical methods to compute an anomalous score for the individual vertices of a respective graph, such as checking the local topology of a node, random walks, and complex neural networks. Leveraging the structure of the graph, the first quantum algorithm is proposed to calculate the anomaly score of each node by continuously traversing the graph with a uniform starting position for all nodes. The proposed algorithm incorporates well-known characteristics of quantum walks, and, taking into consideration the noisy intermediate-scale quantum (NISQ) era and subsequent intermediate-scale quantum (ISQ) era, an adjustment to the algorithm is provided to mitigate the increasing depth of the circuit.

These modifications are achieved through layer-by-layer (LbL) assembly, resulting in a reduced light transmission and a spectral red shift. Subsequent annealing restores transmission and induces a spectral blue shift. A similar effect is observed under low-pressure annealing when a mirror is installed on the facet of the modified fibers.

It is now understood that quantum steering plays a pivotal role in asymmetric quantum information tasks. In this work, a scheme is proposed to generate asymmetric steering between two mechanical modes by transferring quantum coherence from a correlated-emission laser. To accomplish this, quantum Langevin equations is derived to describe the optomechanical coupling between two cavity modes and two mechanical modes along with the master equation of two-mode laser. By examining the case where the cavity modes scatter at the anti-Stokes sidebands, it is demonstrated that both two-way and one-way steering can be achieved by adjusting the strength of the field driving the gain medium of the laser. Furthermore, it is showed that the direction of one-way steering can be controlled by varying the temperatures of the mechanical baths or the strengths of the optomechanical couplings. Additionally, it is revealed that the directionality of one-way steering depends on the modes fluctuation levels of the modes, with the mode exhibiting larger fluctuations determining the direction.
