Physica A: Statistical Mechanics and its Applications, 2019 As an application of the classically decayable correlation in a quantum chaos system maintained over an extremely long time-scale (Matsui et al, Europhys.Lett. 113(2016),40008), we propose a minimal model of quantum damper composed of a quantum harmonic oscillator (HO) weakly interacting with a bounded quantum chaos system.

Damping rate limitations for transverse dampers in large hadron colliders [PDF]
, 2020 The paper focuses on two issues important for design and operation of bunch-by-bunch transverse damper in a very large hadron collider, where fast damping is required to suppress beam instabilities and noise induced emittance growth.

Study on the Development of Passive MR Damper with Displacement-Dependent Damping Characteristics
Journal of Fluid Science and Technology, 2010 In this paper, we propose a new concept of a magneto-rheological (MR) fluid damper, which is a passive MR fluid damper. The passive MR damper has no electrical devices, such as a sensor, power supply and controller, and hence, it has an advantage in ...

APPLICATION OF MR DAMPERS TO VARIABLE DAMPERS
Doboku Gakkai Ronbunshu, 2004 ダンパーの減衰力を任意に変化させることができれば, 橋梁の地震応答を抑える上で有利であり, 構造物の応答に応じて特性を変化させることのできるバリアブルダンパーの利用が効果的であると考えられている. 本研究では, 電流で減衰力を制御可能なMRダンパーを用いたバリアブルダンパーの有効性を実験, 解析の両面から検討する. 小型MRダンパーの特性を明らかにすることを目的として繰り返し載荷実験を行った後, 模型橋の振動台加振実験を行い, 地震時のMRダンパー及び橋梁の挙動を調べた. また, バリアブルダンパーをモデル化し, 橋の地震応答を地震応答解析によってよく再現できることを示した.
