Scrambling dynamics and many-body chaos in a random dipolar spin model
Ahmet Keles, Erhai Zhao, W. Vincent Liu
Is there a quantum many-body system that scrambles information as fast as a black hole? The Sachev-Ye-Kitaev model can saturate the conjectured bound for chaos, but it requires ran…

Renormalization group analysis of dipolar Heisenberg model on square lattice
Ahmet Keles, Erhai Zhao
We present a detailed functional renormalization group analysis of spin-1/2 dipolar Heisenberg model on square lattice. This model is similar to the well known - model an…

Absence of long-range order in a triangular spin system with dipolar interactions
Ahmet Keles, Erhai Zhao
Antiferromagnetic Heisenberg model on the triangular lattice is perhaps the best known example of frustrated magnets, but it orders at low temperatures. Recent density matrix renor…
