Aging Phase Diagram and Exact Asymptotic Energies of Mixed Spherical Spin Glasses
Johannes Lang, Vincenzo Citro, Luca Leuzzi +1
We determine the aging phase diagram of mixed spherical -spin glasses quenched from random configurations to zero temperature. Solving the asymptotic dynamical equations of…
Revealing the Spin Hydrodynamics of a Spin-Imbalanced Unitary Fermi Gas
DeChao Zhang, Johannes Lang, J. E. Thomas
Hydrodynamics governs diverse collective phenomena in nature, from the expansion of a quarkgluon plasma to viscous electron flow in quantum materials. In strongly interacting hydro…
DYNAMITE: A high-performance framework for solving Dynamical Mean-Field Equations
Johannes Lang, Vincenzo Citro, Luca Leuzzi +1
Understanding the dynamics of systems evolving in complex and rugged energy landscapes is central across physics, economics, biology, and computer science. Disordered mean-field mo…
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…
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…
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…
