Scrambling dynamics across a thermalization-localization quantum phase transition
Subhayan Sahu, Shenglong Xu, Brian Swingle
We study quantum information scrambling, specifically the growth of Heisenberg operators, in large disordered spin chains using matrix product operator dynamics to scan across the…
Locality, Quantum Fluctuations, and Scrambling
Shenglong Xu, Brian Swingle
Thermalization of chaotic quantum many-body systems under unitary time evolution is related to the growth in complexity of initially simple Heisenberg operators. Operator growth is…
Accessing scrambling using matrix product operators
Shenglong Xu, Brian Swingle
Scrambling, a process in which quantum information spreads over a complex quantum system becoming inaccessible to simple probes, happens in generic chaotic quantum many-body system…
Ferromagnetism and Wigner crystallization in Kagome graphene and related structures
Yuanping Chen, Shenglong Xu, Yuee Xie +3
Interaction in a flat band is magnified due to the divergence in the density of states, which gives rise to a variety of many-body phenomena such as ferromagnetism and Wigner cryst…
