Quantum Reservoir Computing with Physics-Informed Correction for Reduced-Order PDE Forecasting
Krishna Bhatia, Harsh, Shalini Devendrababu
We study a hybrid proposal--correction architecture for reduced-order PDE forecasting in which a pure-state quantum reservoir computer (QRC) predicts latent coefficient dynamics an…
Octupolar Gravitational Radiation in de Sitter Spacetime
Harsh, Omkar Shetye, Amitabh Virmani
We derive the gravitational radiation generated by a localised matter source in de Sitter spacetime at octupolar order in the multipolar expansion, working in generalised harmonic…
Consistent Truncation of Linearized gravitational waves in de Sitter space-time
Ghanashyam Date, Harsh
An important step in using observations of gravitational waves from bounded sources is to relate the observed waveforms far away from a source to the local dynamics and environment…
de Sitter Teukolsky waves
Harsh, Sk Jahanur Hoque, Sitender Pratap Kashyap +1
We present de Sitter Teukolsky waves -- linearised quadrupolar gravitational waves in the transverse-traceless gauge in de Sitter spacetime. In the cosmological constant going…
