Best for students, researchers, and serious astronomy enthusiasts.\u003c\/p\u003e\n\u003cp\u003eIn this thesis, ultimate sensitive measurement for weak force imposed on a suspended mirror is performed with the help of a laser and an optical cavity for the development of gravitational-wave detectors. According to the Heisenberg uncertainty principle, such measurements are subject to a fundamental noise called quantum noise, which arises from the quantum nature of a probe (light) and a measured object (mirror). One of the sources of quantum noise is the quantum back-action, which arises from the vacuum fluctuation of the light. It sways the mirror via the momentum transferred to the mirror upon its reflection for the measurement. The author discusses a fundamental trade-off between sensitivity and stability in the macroscopic system, and suggests using a triangular cavity that can avoid this trade-off. The development of an optical triangular cavity is described and its characterization of the optomechanical effect in the triangular cavity is demonstrated. As a result, for the first time in the world the quantum back-action imposed on the 5-mg suspended mirror is significantly evaluated. This work contributes to overcoming the standard quantum limit in the future.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Default Title","offer_id":46417170137287,"sku":"1-99-520-000249","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/9575\/6487\/files\/9784431558804.jpg?v=1776287387","url":"https:\/\/snowflakeskies.com\/products\/classical-pendulum-feels-quantum-back-action-2016","provider":"Snowflake Skies","version":"1.0","type":"link"}
