Digital Twin Modeling of Quantum Dynamical Systems: Dissipative Quantum Reservoir Computing
Abhijit Sen, Bikram Keshari Parida, Shital Chauhan +2
Modeling the response of driven many-body quantum systems from input--output data is difficult: the dynamics are nonlinear, history dependent, and expensive to simulate as system s…
Exploration of Zero-Complexity Compact Stars in Higher Dimensions under the Finch-Skea Background
Shyam Das, Megandhren Govender, Kevin Reddy +1
Motivated by the recent extension of Herrera's gravitational complexity to arbitrary higher-dimensional spacetimes, we investigate exact compact-star models that satisfy the vanish…
K-U-KAN: Koopman-Enhanced U-KAN for 3D Dental Reconstruction from a Single Panoramic X-ray Radiograph
Bikram Keshari Parida, Abhijit Sen, Wonsang You
A panoramic X-ray compresses a 3D jaw into a 2D strip; we aim to recover the missing depth cleanly and fast. Existing implicit neural representations render realistic volumes but a…
Geometric Kolmogorov--Arnold Network (GeoKAN)
Abhijit Sen, Bikram Keshari Parida, Giridas Maiti +2
We introduce Geometric Kolmogorov--Arnold Networks (GeoKANs), a family of geometry-aware KAN-type models in which approximation is carried out in learned, geometry-adapted coordina…
Feature Engineering is Not Dead: Reviving Classical Machine Learning with Entropy, HOG, and LBP Feature Fusion for Image Classification
Abhijit Sen, Giridas Maiti, Bikram K. Parida +3
Feature engineering continues to play a critical role in image classification, particularly when interpretability and computational efficiency are prioritized over deep learning mo…
Input-Output Optics as a Causal Time Series Mapping: A Generative Machine Learning Solution
Abhijit Sen, Bikram Keshari Parida, Kurt Jacobs +1
The response of many-body quantum systems to an optical pulse can be extremely challenging to model. Here we explore the use of neural networks, both traditional and generative, to…
Panorama Tomosynthesis from Head CBCT with Simulated Projection Geometry
Anusree P. S., Bikram Keshari Parida, Seong Yong Moon +1
Cone Beam Computed Tomography (CBCT) and Panoramic X-rays are the most commonly used imaging modalities in dental health care. CBCT can produce three-dimensional views of a patient…
Physics Informed Kolmogorov-Arnold Neural Networks for Dynamical Analysis via Efficent-KAN and WAV-KAN
Subhajit Patra, Sonali Panda, Bikram Keshari Parida +4
Physics-informed neural networks have proven to be a powerful tool for solving differential equations, leveraging the principles of physics to inform the learning process. However,…
Lévy-Leblond Equation and Eisenhart-Duval lift in Koopman-von Neumann Mechanics
Bikram Keshari Parida, Abhijit Sen, Shailesh Dhasmana +1
The Koopman-von Neumann (KvN) mechanics is an approach that was formulated long ago to answer the question regarding the existence of a Hilbert space representation of classical me…
Eisenhart lift of Koopman-von Neumann mechanics
Abhijit Sen, Bikram Keshari Parida, Shailesh Dhasmana +1
The Eisenhart lift establishes a fascinating connection between non-relativistic and relativistic physics, providing a space-time geometric understanding of non-relativistic Newton…
Anisotropic compact star with a linear pressure-density relationship
Shyam Das, Bikram Keshari Parida, Koushik Chakraborty +1
We present a model of compact astrophysical object under General Theory of Relativity using the anisotropic extension of Tolman IV solution. The anisotropy function, derived from t…
Anisotropic compact stars: Constraining model parameters to account for physical features of tidal Love numbers
Shyam Das, Saibal Ray, Maxim Khlopov +2
In this paper, we develop a new class of models for a compact star with anisotropic stresses inside the matter distribution. By assuming a linear equation of state for the anisotro…
Tidal love number of a static spherically symmetric anisotropic compact star
Shyam Das, Bikram Keshari Parida, Ranjan Sharma
Tidal deformability of a coalescing neutron star subjected to an external tidal field plays an important role in our probe for the structure and properties of compact stars. In par…
