GENERAL LECTURE 5 : Make Optical Lattice Clocks Compact and Useful for Real-world Applications (Friday 24 May, 2024)

 

Speaker : Prof. Hidetoshi Katori (The University of Tokyo, Japan)

 

Dr. (Prof.) Hidetoshi Katori is a Professor at the Department of Applied Physics, Graduate School of Engineering, University of Tokyo, Japan. He is also the chief scientist at Quantum Metrology laboratory, Riken, leading the Space-Time Engineering research team at Riken, Japan.   He served as a Distinguished Professor at the University of Tubingen, Germany.

Professor Katori is widely regarded as the inventor of “Neutral atom-based optical lattice clocks”. In early 2000s, his work related to “Ultrastable Optical Clock with Neutral Atoms in an Engineered Light Shift Trap”, and its demonstration in 2005 has provided the breakthrough for the start of work on optical lattice clocks and its various applications in timekeeping, geodesy, and fundamental physics. He demonstrated optical lattice clocks with Strontium(Sr), Ytterbium(Yb), Mercury (Hg) and Cadmium (Cd) neutral atoms. He measured the frequency ratios between Sr, Yb and Hg atoms, a prerequisite for the adoption of optical atomic clocks as the primary time standard and is a highly cited work. Neutral atom optical lattice clocks are one of the primary candidates for the re-definition of the SI second and already has been accepted as the secondary representation of the second.

Recently, Prof. Katori started experimenting on a compact transportable optical lattice clocks for field experiments. Dr. Katori demonstrated geodesy by using Einstein’s relativity idea that two clocks at different heights will be ticking at different rates. He did the famous Tokyo-Skytree experiment where he took one of his transportable clocks to one of the viewer's gallery and demonstrated height difference measurement at centimeter level accuracy.

Prof. Katori group is also involved in the research for Thorium based nuclear clock and has recently been successful in the measurement of energy of 229Th nuclear clock isomer. He proposed the idea for “Internet of clocks” for various geoscience-related measurements like earthquakes, which has opened up a new field of application for such clocks.

He led various prestigious projects like CREST (Japan science & technology), ERATO Katori innovative space-time project, the JST Mirai program etc. Prof. Katori has been a recipient of many prestigious awards. To name a few in this long list is Julius springer prize (2005), RABI award (2008), The Philipp Franz von Siebold prize (2011), Micius quantum prize (2020), Breakthrough prize in Fundamental Physics (2021),  the 20th IBM Japan science award (2006), The Asahi prize (2011), Medal with Purple ribbon (2014), The 54th Fujihara award (2013), The 14th Leo Esaki Prize (2017), The Honda prize (2022).

ABSTRACT

Energy is at the center of all our activities, especially now, that electricity become a need for basic human survival. Nevertheless, the resources are limited and on certain occasions, we need to rely on the opportunity to have specific energy availability and energy on demand, so that sensors, emergency communications, and electrical operated devices, in general, continue to operate even if the energy grid is not there. All electrical mobile solutions depend heavily on batteries including electric cars, with the burden chemical batteries bring to environmental pollution.

If we can deliver energy using electromagnetic waves the same breakthrough we had seen in the last century with wireless communications, will be a reality also with wireless energy. Delivering energy where we need it and when we need it, including the removal of batteries from electrical devices, and relocating the energy from the sun to earth using space-based solar power, with a 24/24h energy availability, will make a change in how we see energy problems.

In this talk, we will discuss the electricity generation problem and how to cope with the huge demand for electrical-based technologies. We will address new paradigms for electromagnetic energy transmission, and alternatives to make energy available when needed and where needed. With these solutions, Net Zero energy alternatives will be available everywhere and can be a step forward in human development.

COURSE PROGRAM

Sunday, May 19, 10:40-18:00

10:40 – 12:40 – Wireless Power Transmitter and Receiver Efficiency Optimization

During this talk, we will delve into the intricate realm of Wireless Power Transfer (WPT) transmitters and receivers, with a particular focus on addressing the challenge of efficiency. Efficiency stands as a pivotal concern in WPT systems, influencing their practical applicability across various domains. Our discussion will encompass an exploration of current efficiency limitations. Moreover, we will deliberate on innovative strategies and emerging technologies aimed at enhancing the efficiency of WPT systems. By collectively examining these issues and brainstorming potential solutions, we aim to foster a comprehensive understanding and pave the way for advancements in the field of wireless power transfer.

Instituto de Telecomunicações - Universidade de Aveiro, Portugal

12:40-13:40 – Lunch Break

13:40 – 15:40 - High Efficiency Rectenna Theory and Technology for Far Field Wireless Power

For practical wireless power transfer (WPT) system, we need high efficiency rectenna, rectifying antenna. For wide beam WPT or an energy harvesting, we need the high efficiency rectenna in low input microwave power. On contrary, in narrow beam WPT, we need high power rectenna or rectenna array technology to receive focusd microwave power. The rectenna has interesting characteristics when we design it as combination of the antenna and the rectifying circuit with a diode. In this talk, I explain the basic theory of the rectenna and its novel technology for the practical far field WPT.

Professor, Kyoto University, Japan

15:40-16:00 – Break

16:00 – 18:00 - Harmonic Backscattering: a path towards energy-autonomous clutter-insensitive wireless sensing

This session will provide an overview of the current status of backscatter radios that rely on harmonic generation. We will start describing the basics of harmonic generation. Examples of simple zero-biased frequency doublers will be provided. Then, we will discuss approaches to achieve compact harmonic antenna systems. Solutions involving green materials such as cardboard will be provided. Finally, we will describe state-of-the-art sensing solutions based on harmonic transponders, including temperature sensors, rotational speed sensors, vibration sensors. We will highlight the pros and cons of each approach and we will sketch possible evolution scenarios.
