Strain-Induced Relaxor Multiferroicity at Room Temperature in Hexaferrite BaFe12O19 Thin Films
Yilin Evan Li, Harikrishnan KP, Sankalpa Hazra +19
Multiferroic materials that combine magnetic and electric order at room temperature are rare. Here, we demonstrate strain-induced room-temperature polar order in the ferrimagnetic…
Tracking Dynamical Transitions using Link Density of Recurrence Networks
Rinku Jacob, R. Misra, K P Harikrishnan +1
We present Link Density (LD) computed from the Recurrence Network (RN) of a time series data as an effective measure that can detect dynamical transitions in a system. We illustrat…
Recurrence measures and transitions in stock market dynamics
Krishnadas M., K. P. Harikrishnan, G. Ambika
The financial markets are understood as complex dynamical systems whose dynamics is analysed mostly using nonstationary and brief data sets that usually come from stock markets. Fo…
Quantifying information loss on chaotic attractors through recurrence networks
K. P. Harikrishnan, R. Misra, G. Ambika
We propose an entropy measure for the analysis of chaotic attractors through recurrence networks which are un-weighted and un-directed complex networks constructed from time series…
Higher order spectral analysis of ECG signals
Yamini Kotriwar, Sneha Kachhara, K. P. Harikrishnan +1
Higher Order Spectral (HOS) analysis is often applied effectively to analyze many bio-medical signals to detect nonlinear and non-Gaussian processes. One of the most basic HOS meth…
Degree weighted recurrence networks for the analysis of time series data
Rinku Jacob, K. P. Harikrishnan, R. Misra +1
Recurrence networks are powerful tools used effectively in the nonlinear analysis of time series data. The analysis in this context is done mostly with unweighted and undirected co…
