More is different. We study how.
We study states of quantum matter in and out of equilibrium, with a focus on collective quantum phenomena. Our work sits where condensed matter physics, statistical mechanics and quantum information meet.

All research themes- Quantum chaos in open systems
What does chaos look like when a quantum system leaks into its environment? We study the spectra of Liouvillians and non-Markovian generators, random-matrix universality, and how relaxation and thermalization work away from isolation.
11 papers since 2024 - Driven matter and transport
Voltage, temperature bias and noise push matter into states with no equilibrium counterpart. We study non-equilibrium phase transitions, current fluctuations, impurity models and universal transport laws.
5 papers since 2024 - Quasiperiodic and moiré materials
Incommensurate potentials and moiré superlattices produce localization, multifractality and new kinds of order. We look for the phases these systems host and how interactions and disorder change them.
11 papers since 2024 - Quantum information and noisy devices
Real quantum processors are noisy. We use many-body and random-matrix tools to describe error accumulation, error mitigation and correction, tomography of open systems, and monitored dynamics.
7 papers since 2024 - Localization, constraints and gauge theories
Conservation laws can freeze or slow dynamics. We study many-body localization, fractonic and multipole-conserving systems, non-Hermitian skin effects and lattice gauge theories.
