75. Structural Transitions and Stochastic Dynamics in Trapped Ion Crystals

21/04/2026, 10:30

Speaker:
Prof Sadiq Rangwala
Raman Research Institute

Abstract:
We present a new ion trap experiment, with an end cap type Paul trap built for precision spectroscopy and metrology [1,2]. We will discuss the performance of this experiment and then move quickly to the observation of three dimensional trapped ion crystals of Ca+ ions. The crystals form when the ions attain their...

76. Evaluating Excess Micromotion in an Asymmetric Segmented Trap for Ytterbium Optical Clocks

21/04/2026, 11:00

Speaker:
Dr Piyaphat Phoonthong
National Institute of Metrology (Thailand)

Abstract:
In this work, we present an evaluation of excess micromotion within a linear, asymmetric segmented Paul trap developed at the National Institute of Metrology, Thailand (NIMT). To characterize the micromotion amplitude, we employ the photon correlation method, which utilizes the correlation...

77. Ytterbium ion based Optical Clock: Possible way for Redefining SI Second

Speaker:
Prof Subhasis Panja
CSIR-National Physical laboratory
Academy of Scientific & Innovative Research

Abstract:
Present definition of time and frequency is based on a microwave transition of laser cooled Cesium atoms. The variance of the measurement “Allan Deviation” is inversely proportional to the resonance frequency, so an optical frequency standard at resonance...
