Autoregressive Projective Quantum Monte Carlo: From a Hermitian to a Non-Hermitian Perspective
Lavoisier Wah, Remmy Zen, Flore K. Kunst
Accurately determining the ground-state properties of quantum many-body systems remains a central challenge. In this work, we introduce an autoregressive projective quantum Monte C…
Many-Body Mobility Edge and Non-Hermitian Skin Effect in an Interacting Quasi-Periodic Spin Chain
Lavoisier Wah, Ayan Banerjee, Flore K. Kunst
Non-Hermitian many-body physics reveals a rich interplay between topology, localization, and boundary effects, yet their collective behavior in interacting disordered systems remai…
Bridging Frustration and Non-Hermiticity via COMPASS: An Adaptive Biorthogonal Neural Quantum State Framework
Lavoisier Wah, Flore K. Kunst, Mohamed Hibat-Allah
In this work, we introduce a complementary optimization method for progressive and adaptive state search (COMPASS) based on biorthogonal adaptive recurrent neural quantum states. O…
Many-Body Neural Network Wavefunction for a Non-Hermitian Ising Chain
Lavoisier Wah, Remmy Zen, Flore K. Kunst
Non-Hermitian (NH) quantum systems have emerged as a powerful framework for describing open quantum systems, non-equilibrium dynamics, and engineered quantum optical materials. How…
