Ando Lab Midterm Seminar May 9, 2018 Optimizing the Future 2018 Yuta Michimura Department of Physics, University of Tokyo
Contents • Looking back on the year 2017 • My plans and expectations for the year 2018 • Looking back over the past years • Interesting-looking experiments (canceled) 2
Ando Lab Vision 2017 • What did I say last year? • KAGRA • Rotating TOBA • Cryogenic TOBA • Gravitational inverse square law • Macroscopic quantum mechanics • Lorentz invariance test 3
KAGRA Y. Enomoto • Some are addressed, some are not • Worked on actuators, sensitivity update, green, electronics and cables, O3 configuration and PE, …… ALS business MZI simulation with K. Yamamoto K. Nagano et al. K. Komori? PSO Parameter estimation 4
Rotating TOBA • Not much progress… • But I still think it is worth a try 5
Cryogenic TOBA • T. Shimoda working on cryogenics • Ching Pin working on Q-value measurements • K. Komori worked on thermal noise calculations with non- uniform temperature Particle Swarm Optimization! 6
Gravitational Inverse Square Law • Not much progress… • But, in terms of search for non- standard forces… Axion Dark Matter! 7
Macroscopic Quantum Mechanics • K. Komori working on torsion pendulum • CSL experiments done by B4 • Good progress in optical levitation experiments - more laser power - possibility of making a curved mirror at ~10 mg scale • Should be very close to horizontal restoring force confirmation • Get high power laser 8
Lorentz Invariance Test • Good progress - compact turntable with wireless signal extraction - first monolithic optical cavity integrated with input optics - reached world best precision in one week • Observation! • Bit bigger (and more stable) turntable 9
My Plans 2018 • Finish axion paper. • Finish bKAGRA Phase-1 paper. • More investigation on sensitivity optimization for parameter estimation (incorporate detection rate, aLIGO/AdV sensitivity dependence, IM parameters, squeezing, polarization optimization). • Realistic feasibility study for KAGRA+. • Virgo visit from June 4 to August 18. • KAGRA interferometer works from August (or October?). • Summarize KAGRA lock acquisition scheme, including ALS and MZI modulation. • In-vac RF PD and RF QPD. 10
My Expectations 2018 • Observe radiation pressure noise with torsion pendulum. • Horizontal restoring force confirmation for optical levitation. • Fabricate ~10 mg curved mirror. • Start observation for Lorentz violation search, summarize the current setup. • Some experimental result at cryogenic temperatures. • Start DECIGO experiment. 11
What I Did 2017 ANU, GWADW TAUP JPS LNPC KIW Tohoku F2F JPS F2F Nagoya JPS Axion Brown ALS, MZI, electronics Actuator paper Phase 2 schedule, sensitivity NonEq thermal noise paper KAGRA+ Sensitivity PSO, PE Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar 2017 2018 12
My Schedule 2018 Fukuoka MG (LVC) JPS (GWPAW) (France?) GWADW KIW F2F JPS (JGRG) F2F (KIW) F2F? PSO, PE, KAGRA+ Summarize KAGRA electronics ALS, MZI Phase 1 paper Brown Axion Virgo KAGRA interferometer Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar 2018 2019 13
Why Virgo, Now? • 若手研究者の国際展開事業 started this year • Never been to Virgo • Exciting to join Virgo commissioning towards O3 • After bKAGRA Phase 1, before RSE 14

Interesting-looking Experiments • The grass is always greener on the other side. • It is also important to concentrate on your own work. • But, of course, I’m not saying that we should be narrow - minded. • And I know elder people are narrow-minded. • You have to be clever enough to enlighten elder people. 16
