Experimental Demonstration of Higher Precision Weak-Value-Based Metrology Using Power Recycling

2016-11-29T10:00:00-05:00

Author(s): Yi-Tao Wang, Jian-Shun Tang, Gang Hu, Jian Wang, Shang Yu, Zong-Quan Zhou, Ze-Di Cheng, Jin-Shi Xu, Sen-Zhi Fang, Qing-Lin Wu, Chuan-Feng Li, and Guang-Can Guo
The weak-value-based metrology is very promising and has attracted a lot of attention in recent years because of its remarkable ability in signal amplification. However, it is suggested that the upper limit of the precision of this metrology cannot exceed that of classical metrology because of the l…

Top Quark Mass Calibration for Monte Carlo Event Generators

2016-11-29T10:00:00-05:00

Author(s): Mathias Butenschoen, Bahman Dehnadi, André H. Hoang, Vicent Mateu, Moritz Preisser, and Iain W. Stewart
The most precise top quark mass measurements use kinematic reconstruction methods, determining the top mass parameter of a Monte Carlo event generator m_{t}^{MC}. Because of hadronization and parton-shower dynamics, relating m_{t}^{MC} to a field theory mass is difficult. We present a calibration pr…

Ultrafast Coherent Dynamics of a Photonic Crystal All-Optical Switch

2016-11-29T10:00:00-05:00

Author(s): Pierre Colman, Per Lunnemann, Yi Yu, and Jesper Mørk
We present pump-probe measurements of an all-optical photonic crystal switch based on a nanocavity, resolving fast coherent temporal dynamics. The measurements demonstrate the importance of coherent effects typically neglected when considering nanocavity dynamics. In particular, we report the observ…
