A briefly formulated update of the recently published review [B.A. Malomed, Multidimensional soliton systems. Adv. Phys. 9(1) (2024), pp. 2301592] on the topic of multidimensional solitons (chiefly, in nonlinear optics and atomic Bose–Einstein condensates (BECs)) is presented. The update briefly summarizes some notable results on this topic that have been reported very recently, and offers a compact outline of the directions of the current experiment and theoretical work in this and related fields. In particular, as concerns newest experimental findings, included are the creation of multiple quantum droplets in prolate BEC, and the observation of expanding toroidal light structures in linear optics. The update of theoretical results includes the analysis of 2D solitons in the optical system with the quadratic nonlinearity and fractional diffraction, and the prediction of stable 3D vortex solitons in various BEC schemes with long-range interactions.

Despite being the simplest element, hydrogen (H) exhibits complex behavior in materials due to its unique ambipolar character. In particular, it is recognized as one of the most important impurities in semiconductor physics, because H is often unintentionally incorporated into materials and significantly influences the electrical properties of the host material. One of the few means that have been applied to obtain experimental information about the local electronic state of diluted H is the use of muon (Mu) as pseudo-H. Here, we present an overview on the “ambipolarity model” that provides a new paradigm for the microscopic understanding of Mu-related defects. Its essence lies in the fact that the information Mu yields is not about the equilibrium double-charge transition level () but about the donor/acceptor levels ( and ) associated with the relaxed-excited states of Mu. Most notably, the model resolves serious discrepancies between the implications from implanted-Mu studies and theoretical predictions on the electronic state of H from ab initio density functional theory calculations in oxide semiconductors that have hindered the coherent integration of both Mu and H knowledge. The model also suggests that hydride state (H) plays important roles in oxide materials, as found in a variety of recent examples. Based on these successes, the model is currently serving as a reliable guide for the interpretation of various Mu states observed in other insulating materials, for which several recent examples are presented.
尽管氢（H）是最简单的元素，但由于其独特的两极特性，它在材料中表现出复杂的行为。特别是，它被认为是半导体物理学中最重要的杂质之一，因为氢经常被无意地掺入材料中，并显著影响主材料的电学特性。利用μ介子（Mu）作为伪氢气，是获得稀释氢气局部电子态实验信息的少数方法之一。在此，我们概述了 "安培极性模型"，它为从微观上理解与μ介子有关的缺陷提供了一种新的范式。其本质在于，Mu 所产生的信息不是关于平衡双电荷转换电平（E+/-），而是关于与 Mu 的弛豫激发态相关的供体/受体电平（E0/- 和 E+/-0）。最值得注意的是，该模型解决了植入式 Mu 研究与氧化物半导体中原子密度泛函理论计算对 H 电子状态的理论预测之间的严重差异，这些差异阻碍了 Mu 和 H 知识的协调整合。该模型还表明，氢化物态（H-）在氧化物材料中发挥着重要作用，这在最近的各种实例中都有发现。基于这些成功经验，该模型目前已成为解释在其他绝缘材料中观察到的各种 Mu 状态的可靠指南，并介绍了最近的几个实例。

Thin films based on silicon and transition-metal elements dominate the semiconducting industry and are ubiquitous in all modern devices. Films have also been produced in the rare-earth series of elements for both research and specialized applications. Thin films of uranium and uranium dioxide were fabricated in the 1960s and 1970s, but there was little sustained effort until the early 2000s. Significant programmes started at Oxford University (transferring to Bristol University in 2011), and Los Alamos National Laboratory (LANL) in New Mexico, USA. In this review we cover the work that has been published over the last ~20 years with these materials. Important breakthroughs occurred with the fabrication of epitaxial thin films of initially uranium metal and UO2, but more recently of many other uranium compounds and alloys. These have led to a number of different experiments that are reviewed, as well as some important trends. The interaction with the substrate leads to differing strain and hence changes in properties. An important advantage is that epitaxial films can often be made of materials that are impossible to produce as bulk single crystals. Examples are U3O8, U2N3 and alloys of U-Mo, which form in a modified bcc structure. Epitaxial films may also be used in applied research. They represent excellent surfaces, and it is at the surfaces that most of the important reactions occur in the nuclear fuel cycle. For example, the fuel-cladding interactions, and the dissolution of fuel by water in the long-term storage of spent fuel. To conclude, we discuss possible future prospects, examples include bilayers containing uranium for spintronics, and superlattices that could be used in heterostructures. Such applications will require a more detailed knowledge of the interface interactions in these systems, and this is an important direction for future research.

Path integrals are a ubiquitous tool in theoretical physics. However, their use is sometimes hindered by the lack of control on various manipulations -- such as performing a change of the integration path -- one would like to carry out in the light-hearted fashion that physicists enjoy. Similar issues arise in the field of stochastic calculus, which we review to prepare the ground for a proper construction of path integrals. At the level of path integration, and in arbitrary space dimension, we not only report on existing Riemannian geometry-based approaches that render path integrals amenable to the standard rules of calculus, but also bring forth new routes, based on a fully time-discretized approach, that achieve the same goal. We illustrate these various definitions of path integration on simple examples such as the diffusion of a particle on a sphere.
