Consequently, any physical quantity expressed by discrete topological invariants is unprecedentedly robust against large perturbations. The 2016 Nobel Prize in physics was awarded for research on topological physics. Likewise, photonics is also benefiting from band topologies—discrete global configurations of wave-functions in the Brillouin zone of periodic systems such as photonic crystals. Using topological photonics, photon transport without any localization and scattering loss is now feasible. Since the concept of photonic crystals was first proposed in 1987, Group L01 has been working on experiments with periodic dielectric materials. In 1994, our group reported laser-assisted crystallization of polystyrene spheres and strontium titanate (SrTiO3) particles (n = 2.5) with lattice constants of ~1.5 μm (1). Such photonic crystals are characterized by their band structures, while the hidden freedom of band topology was only unveiled in 2005. Topological photonics started with the proposal of a one-way waveguide as the edge state of a two-dimensional (2D) photonic crystal, which was experimentally demonstrated in 2009. In the following year, our group published the second set of experimental results (2) on this topic in the context of microwave frequencies. The idea is illustrated in Figure 1A. The edge mode of a magnetic photonic crystal has a gapless dispersion curve traversing the whole bandgap, connecting the bulk bands above and below. The group velocity of the edge mode has only one sign and propagates in one direction only, without scattering from arbitrary defects. Such a one-way edge state is analogous to the chiral edge state in the quantum Hall effect, providing a novel mechanism for planar integration of nonreciprocal photonic devices. In three dimensions, optical fibers are the best light guides and are ubiquitous in modern technologies. Using high-dimensional band topologies, we have shown that one-way fibers can be designed using 3D magnetic photonic crystals (3), as illustrated in Figure 1B.

Bhattacharyya, Jyotirmoy Guha","doi":"10.1088/978-0-7503-2715-2ch11","DOIUrl":"https://doi.org/10.1088/978-0-7503-2715-2ch11","url":null,"abstract":"Einstein, Podolsky, and Rosen (EPR) were concerned with the following issue. Given two spatially separated quantum systems A and B and an appropriate initial entangled state, a measurement of a property on system A can be an indirect measurement of B in the sense that from the outcome of the A measurement one can infer with probability 1 a property of B, because the two systems are correlated. There are cases in which either of two properties of B represented by noncommuting projectors can be measured indirectly in this manner, and EPR argued that this implied that system B could possess two incompatible properties at the same time, contrary to the principles of quantum theory. In order to understand this argument, it is best to apply it to a specific model system, and we shall do so using Bohm's formulation of the EPR paradox in which the systems A and B are two spin-half particles a and b in two different regions of space, with their spin degrees of freedom initially in a spin singlet state (23.2). As an aid to later discussion, we write the argument in the form of a set of numbered assertions leading to a paradox: a result which seems plausible, but contradicts the basic principles of quantum theory. The assertions E1 to E4 are not intended to be exact counterparts of statements in the original EPR paper, even when the latter are translated into the language of spin-half particles. However, the general idea is very similar, and the basic conundrum is the same. E1. Suppose S az is measured for particle a. The result allows one to predict S bz for particle b, since S bz = −S az. E2. In the same way, the outcome of a measurement of S ax allows one to predict S bx since S bx = −S ax. E3. Particle b is isolated from particle a, and therefore it cannot be affected by measurements carried out on particle a. E4. Consequently, particle b must simultaneously possess values for both S bz and S bx , namely the values revealed by the corresponding measurements on particle a, either of which could be carried out in any given experimental run. E5. But this contradicts the basic principles of quantum theory, since in the two-dimensional spin space one cannot simultaneously assign values of both S z and S x to particle b.","PeriodicalId":42828,"journal":{"name":"Nonlinear Optics Quantum Optics-Concepts in Modern Optics","volume":"101 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86647014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
