JYOTIRAJ (RAJ) NATH

DOCTORAL RESEARCHER // THEORETICAL & COMPUTATIONAL CONDENSED MATTER

Doctoral researcher at Massey University (Auckland, New Zealand) within the Prof. Joachim Brand Research Group. Specializing in many-body quantum dynamics, non-equilibrium field theories, and stochastic quantum Monte Carlo propagators.

My computational focus centers on simulating non-linear solitonic dynamics in attractive Bose-Einstein condensates (BECs), real-time Full Configuration Interaction Quantum Monte Carlo (FCIQMC), and non-Hermitian extensions of the 1D Fermi-Hubbard lattice.

PEDIGREE: Inria Paris-Saclay (2025 Research Fellow) • SVNIT Surat (MSc Physics) • QSQT-2025 Organizer • Open-Source Julia Core Contributor (Rimu.jl).
