iTensor

iTensor is a cutting‐edge tensor calculus platform that seamlessly integrates symbolic and numerical computing to empower researchers, educators, and enthusiasts in exploring complex physics phenomena. Our platform leverages advanced computational libraries, such as SymPy for symbolic mathematics and NumPy for high-performance numerical analysis, enabling users to perform intricate calculations in general relativity, astrophysics, and beyond. With iTensor, you can interactively define metric tensors, coordinate systems, and tensor operations, and then visualize outcomes through real‐time simulations. The application supports both symbolic derivations, allowing analytical expressions to be generated and simplified, and numerical computations, offering precise and efficient evaluations on a variety of multidimensional data. This dual approach not only aids in verifying theoretical predictions but also serves as a powerful educational tool that bridges abstract theory and practical application. Our open-source solution features an intuitive web-based interface built with Next.js and a robust Django backend that exposes comprehensive RESTful APIs. Designed with extensibility in mind, iTensor provides advanced features such as customizable simulation parameters, real-time adjustments to gravitational lensing and time dilation effects, and support for future modules including accretion disk dynamics, particle trajectory analysis, and even Hawking radiation visualization. At iTensor, we believe that innovative science should be accessible. We are committed to continuous improvement and collaboration with the research community. Whether you are looking to perform advanced tensor computations or use our platform as a foundation for new astrophysical simulations, iTensor is designed to help you push the boundaries of what is possible in computational physics.
