Cyber - Infrastructure for Climate - Change Research Sudarshan

The amount of data available to climate-change researchers has grown rapidly in the past few years, and the trend is likely to continue. This growth of data has two components: First, advances in data collection and storage technologies permit us to generate data faster (e.g., from sources such as ice cores). Second, advances in the Web and related technologies permit us to easily access data p...

Meaningful Change Detection in Structured Data Sudarshan

Detecting changes by comparing data snapshots is an important requirement for diierence queries, active databases, and version and connguration management. In this paper we focus on detecting meaningful changes in hierarchically structured data, such as nested-object data. This problem is much more challenging than the corresponding one for re-lational or at-le data. In order to describe change...

Non-classicality criteria: Glauber–Sudarshan P function and Mandel parameter

We calculate exactly the quantummechanical, temporalWigner quasiprobability density for a singlemode, degenerate parametric amplifier for a system in the Gaussian state, viz., a displaced-squeezed thermal state. The Wigner function allows us to calculate the fluctuations in photon number and the quadrature variance. We contrast the difference between the non-classicality criteria, which is inde...
