Deeply nonlinear magnon-photon hybrid excitation
Dinesh Wagle, Anish Rai, M. Benjamin Jungfleisch
We investigate the microwave-power dependence of magnon-photon coupling in a yttrium iron garnet-sphere/split-ring-resonator hybrid system at room temperature and demonstrate that…
Spin pumping driven by magnon-polaritons in a ferromagnet-coplanar superconducting resonator hybrid system
Dinesh Wagle, Yi Li, Anish Rai +3
We demonstrate spin pumping driven by a strongly coupled magnon-photon system using a ferromagnet-coplanar superconducting resonator hybrid system at 1.4 K. Electrical readout via…
Identifying Extreme Events in the Stock Market: A Topological Data Analysis
Anish Rai, Buddha Nath Sharma, Salam Rabindrajit Luwang +2
This paper employs Topological Data Analysis (TDA) to detect extreme events (EEs) in the stock market at a continental level. Previous approaches, which analyzed stock indices sepa…
Complex network analysis of cryptocurrency market during crashes
Kundan Mukhia, Anish Rai, SR Luwang +3
This paper identifies the cryptocurrency market crashes and analyses its dynamics using the complex network. We identify three distinct crashes during 2017-20, and the analysis is…
High-Frequency Stock Market Order Transitions during the US-China Trade War 2018: A Discrete-Time Markov Chain Analysis
Salam Rabindrajit Luwang, Anish Rai, Md. Nurujjaman +2
Statistical analysis of high-frequency stock market order transaction data is conducted to understand order transition dynamics. We employ a first-order time-homogeneous discrete-t…
Controlling magnon-photon coupling in a planar geometry
Dinesh Wagle, Anish Rai, Mojtaba T. Kaffash +1
The tunability of magnons enables their interaction with various other quantum excitations, including photons, paving the route for novel hybrid quantum systems. Here, we study mag…

The capability of magnons to hybridize and strongly couple with diverse excitations offers a promising avenue for realizing and controlling emergent properties that hold significan…
Control of magnon-photon coupling by spin torque
Anish Rai, M. Benjamin Jungfleisch
We demonstrate the influence of damping and field-like torques in the magnon-photon coupling process by classically integrating the generalized Landau-Lifshitz-Gilbert equation wit…
Detection and Forecasting of Extreme event in Stock Price Triggered by Fundamental, Technical, and External Factors
Anish Rai, Salam Rabindrajit Luwang, Md Nurujjaman +3
The sporadic large fluctuations are seen in the stock market due to changes in fundamental parameters, technical setups, and external factors. These large fluctuations are termed a…
Direct probing of strong magnon-photon coupling in a planar geometry
Mojtaba Taghipour Kaffash, Dinesh Wagle, Anish Rai +3
We demonstrate direct probing of strong magnon-photon coupling using Brillouin light scattering spectroscopy in a planar geometry. The magnonic hybrid system comprises a split-ring…
A sentiment-based modeling and analysis of stock price during the COVID-19: U- and Swoosh-shaped recovery
Anish Rai, Ajit Mahata, Md. Nurujjaman +2
Recently, a stock price model is proposed by A. Mahata et al. [Physica A, 574, 126008 (2021)] to understand the effect of COVID-19 on stock market. It describes V- and L-shaped rec…
Room-Temperature Intrinsic and Extrinsic Damping in Polycrystalline Fe Thin Films
Shuang Wu, David A. Smith, Prabandha Nakarmi +8
We examine room-temperature magnetic relaxation in polycrystalline Fe films. Out-of-plane ferromagnetic resonance (FMR) measurements reveal Gilbert damping parameters of …
Statistical properties of the aftershocks of stock market crashes revisited: Analysis based on the 1987 crash, financial-crisis-2008 and COVID-19 pandemic
Anish Rai, Ajit Mahata, Md Nurujjaman +1
During any unique crisis, panic sell-off leads to a massive stock market crash that may continue for more than a day, termed as mainshock. The effect of a mainshock in the form of…
