Our research investigates the fundamental behavior of quantum many body systems when they are driven out of balance, far from their natural resting or equilibrium state. In these regimes, standard descriptions break down and rich collective phenomena, strong correlations, and entanglement emerge. Key questions are: How do nonequilibrium quantum systems evolve and settle into steady states, and how can these processes be harnessed to design new quantum technologies? What new phases of matter arise when particles are so strongly linked that none can be understood in isolation? How do information, and entanglement spread through these restless, interacting systems? Ultimately, our work aims to uncover the hidden principles that govern complex quantum matter and to define the fundamental limits of control in quantum materials and devices operating in regimes that challenge our understanding of quantum mechanics.
To address these questions, we use cutting-edge simulations and theory to uncover fundamental quantum effects. Our research spans quantum materials, nanoscale physics, and the frontiers of quantum computing and technology, linking insights into quantum matter with the development and application of next-generation quantum devices.
Simulation & Theory for Fundamental Quantum Effects
Simulation & Theory for Fundamental Quantum Effects
We develop and apply highly precise computational methods to uncover fundamental quantum effects in model systems. By identifying key mechanisms, we track how correlations and emergent phenomena evolve in real time. Our main methodologies are diagrammatic real-time quantum Monte Carlo approaches, but our toolkit also includes tensor-train representations, HEOM, perturbative approaches, and machine learning, allowing us to tackle problems across interaction strengths and timescales.

Quantum Materials
Quantum Materials
We study quantum materials driven far from equilibrium, where strong correlations and collective phenomena give rise to new phases and emergent quasiparticles. By studying transport, optically driven systems, and structured materials, we explore how these systems relax and evolve, sometimes reaching non-thermal steady states. Using tools like dynamical mean field theory (DMFT), we connect microscopic mechanisms to macroscopic observations, uncovering the dynamical principles that govern complex quantum behavior.

Nanoscale Physics
We investigate quantum phenomena at the nanoscale, probing how microscopic mechanisms govern transport in devices such as quantum dots and single molecules in junctions. We study the interplay between nonequilibrium driving and electron-electron or electron-phonon interactions, revealing how feedback through these channels shapes device behavior. Our work connects quantum transport to the underlying chemistry and structure, providing insight into the fundamental principles that control nanoscale systems.

Quantum Technology
We study quantum computing and technologies through the lens of nonequilibrium many-body physics, investigating the microscopic origins of noise and decoherence, and the fundamental limits of these devices. Using theory, simulation, data from quantum hardware, and hybrid quantum-classical approaches, we explore how quantum devices can simulate complex systems while simultaneously challenging numerical methods with their intricate dynamics. This feedback between devices and modeling guides our understanding of near-term NISQ technologies and informs the design of more robust quantum platforms.
