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
The paper presents COMPASS, an adaptive biorthogonal neural quantum state method that combines autoregressive architectures with variational Monte Carlo to reliably find ground sta…
Spectral-topology-induced criticality in non-Hermitian fermionic metals
Ayan Banerjee, Julius T. Gohsrich, Flore K. Kunst
Quantum matter emerges from the interplay of fluctuations, topology, and entanglement, which - in equilibrium - governs quantized transport, universal criticality, and topological…
Multi-dimensional parameter space of higher-order exceptional points induced by Brillouin optoacoustics
Grigorii Slinkov, Anton Montag, Julius T. Gohsrich +4
Exceptional points (EPs) are degeneracies in the spectrum of non-Hermitian systems, where both the eigenvalues and eigenvectors coalesce. In the vicinity of an n-th order EP, the e…
Higher-order exceptional points in a multimode continuum optoacoustic system
Anton Montag, Julius T. Gohsrich, Quentin Levoy +2
Exceptional points appear in non-Hermitian systems as degeneracies, where not only eigenvalues but also eigenvectors coalesce. They are of great theoretical and experimental intere…
