Quantum diffusion in spin chains with phase space methods.
Connecting short-time microscopic dynamics with long-time hydrodynamics in strongly correlated quantum systems is one of the outstanding questions. In particular, it is hard to determine variousExpand

Cluster Truncated Wigner Approximation in Strongly Interacting Systems
We present a general method by which linear quantum Hamiltonian dynamics with exponentially many degrees of freedom is replaced by approximate classical nonlinear dynamics with the number of degreesExpand

Bounds on MAXCUT QAOA performance for p>1
We obtain worst case performance guarantees for $p=2$ and $3$ QAOA for MAXCUT on uniform 3-regular graphs. Previous work by Farhi et al obtained a lower bound on the approximation ratio of $0.692$Expand

Internet Spaceships are Serious Business : Econophysics of EVE Online
In this paper the economic system of the on-line multiplayer game “EVE Online” is analyzed and compared with real economic systems. Using a publicly-available dataset of asks and bids in the primaryExpand
Emergent conservation laws and nonthermal states in the mixed-field Ising model
This paper presents a method of computing approximate conservation laws and eigenstates of integrability-broken models using the concept of adiabatic continuation. Given some Hamiltonian, eigenstatesExpand

This paper describes the Oz Scheduler; a workbench for scheduling problems. Through a graphical interface, the user can freely combine the elements that define a scheduling strategy. Such elementsExpand
Variational Schrieffer-Wolff transformations for quantum many-body dynamics
Building on recent results for adiabatic gauge potentials, we propose a variational approach for computing the generator of Schrieffer-Wolff transformations. These transformations consist of blockExpand
