Our research activities evolve dynamically and are concept-driven rather than method-centric.
This page summarizes the vision and ongoing efforts of the NEUQUAM team. Despite our flexible approach, we maintain a common focus: understanding complex non-equilibrium many-body dynamics through the lens of emergence and universality.
Our overarching goal is to transform many-body light-matter interfaces into beyond-NISQ devices. To achieve this, we investigate the dynamics of driven open AMO systems using tools from condensed matter physics and non-equilibrium statistical mechanics. Ultimately, we aim to develop a universal theory of many-body quantum information that naturally emerges from quantum optics.

A new quantum instability, activated in parametrically driven systems, promotes enhancement of AFM correlations regardless of the nature of order in the starting microscopic spin model. It is about the formation of nesting and Fermi surfaces for magnons, which are notoriously forbidden in thermal states.
