Abstract We briefly review the status of applying quantum squeezing to aid the search for gravitational waves with km-scale laser interferometers operating in the audio frequency band. The target audience is quantum optics professionals who are interested in an easily accessible introduction to the gravitational wave detector, both as an application of squeezing and as a platform for developing other quantum techniques. 1 Background and introduction One of the main thrusts of modern theoretical

Abstract Carbon-based materials (CM) growth techniques include common growth factors for meta-photonics-heterostructure, holographic displays, and lasers. In this article, a review of basic growth using several sources is presented. The solid and gas sources of CVD and PLD techniques are discussed. Additionally, doping types and the fabrication of the CM devices are covered to satisfy the requirements of the light emitters’ functionality in the physics of materials as follows: (a) direct bandga

Abstract A new rare-isotope beam (RIB) accelerator complex, RAON, is under construction in South Korea. RAON employs two RIB production methods, namely, isotope separation online (ISOL) and in-flight fragmentation (IF). According to the original design, ISOL and IF can run independently, and RAON ultimately combines them to provide more neutron-rich ion beams for the experiments. In 2021, due to the delay in developing high-energy superconducting cavities and modules, it was decided to proceed

Abstract Quantum systems are under various unwanted interactions due to their coupling with the environment. Efficient control of quantum system is essential for quantum information processing. Weak-coupling interactions are ubiquitous, and it is very difficult to suppress them using optimal control method, because the control operation is at a time scale of the coherent life time of the system. Nitrogen-vacancy (NV) center of diamond is a promising platform for quantum information processing.

Abstract Classical magnetic fields might change the properties of topological insulators such as the time reversal symmetry protected topological edge states. This poses a question that whether quantized fields would change differently the feature of topological materials with respect to the classical one. In this paper, we propose a model to describe topological insulators (ultracold atoms in square optical lattices with magnetic field) coupled to a tunable single-mode quantized field, and dis

Every year, the Physical Society of Japan presents its Young Scientist Awards to young researchers to recognize outstanding achievements in their early research careers. This year’s winners were recently decided by the board of directors of the JPS based on the recommendations of the selection committees established in 19 divisions of the JPS. The maximum number of winners from each division has been determined based on the number of talks given at the Annual Meetings in the past 3 years. Each

Dr. Eiji Saitoh Professor, Graduate School of Engineering, University of Tokyo 3.1 Pioneering contribution to the physics of spin current The charge of an electron and its flow, the electric current, have always been the main physical quantities of interest in electronics. The angular momentum, or the spin, is another fundamental physical quantity of an electron that generates magnetic moment through its polarization and plays an important role in the physics of magnetism and related engineerin
