Tracking the Catastrophic Collapse of Hybrid Exciton-Phonon Order in a Quantum Material
Omar Abdul-Aziz, Danilo Comini, Johannes Lang +8
Revealing the interactions binding electronic and lattice components of cooperative quantum order is central to sculpting new states of matter. This challenge is epitomized by the…

Fermion quantum criticality far from equilibrium
Rohan Mittal, Tom Zander, Johannes Lang +1
Driving a quantum system out of equilibrium while preserving its subtle quantum mechanical correlations on large scales presents a major challenge, both fundamentally and for techn…

Numerical renormalization of glassy dynamics
Johannes Lang, Subir Sachdev, Sebastian Diehl
The quench dynamics of glassy systems are challenging. Due to aging, the system never reaches a stationary state but instead evolves on emergent scales that grow with its age. This…
