Colloquium: Many-body localization, thermalization, and entanglement
Thermalizing quantum systems are conventionally described by statistical mechanics at
equilibrium. However, not all systems fall into this category, with many-body localization …

Exploring the many-body localization transition in two dimensions
A fundamental assumption in statistical physics is that generic closed quantum many-body
systems thermalize under their own dynamics. Recently, the emergence of many-body …

Slow scrambling in disordered quantum systems
B Swingle, D Chowdhury - Physical Review B, 2017 - APS
In this work we study the effect of static disorder on the growth of commutators—a probe of
information scrambling in quantum many-body systems—in a variety of contexts. We find …

Matter-wave diffraction from a quasicrystalline optical lattice
K Viebahn, M Sbroscia, E Carter, JC Yu… - Physical Review Letters, 2019 - APS
Quasicrystals are long-range ordered and yet nonperiodic. This interplay results in a wealth
of intriguing physical phenomena, such as the inheritance of topological properties from …

Quantum butterfly effect in weakly interacting diffusive metals
We study scrambling, an avatar of chaos, in a weakly interacting metal in the presence of
random potential disorder. It is well known that charge and heat spread via diffusion in such …

Quantum phase transition dynamics in the two-dimensional transverse-field Ising model
The quantum Kibble-Zurek mechanism (QKZM) predicts universal dynamical behavior near
the quantum phase transitions (QPTs). It is now well understood for the one-dimensional …

Onset of many-body chaos in the model
D Chowdhury, B Swingle - Physical Review D, 2017 - APS
The growth of commutators of initially commuting local operators diagnoses the onset of
chaos in quantum many-body systems. We compute such commutators of local field …

Finding matrix product state representations of highly excited eigenstates of many-body localized hamiltonians
A key property of many-body localized Hamiltonians is the area law entanglement of even
highly excited eigenstates. Matrix product states (MPS) can be used to efficiently represent …
