Controlled operations in a strongly correlated two-electron quantum ring

Quantum Simulations of Strongly Correlated Electron Systems

We review recent progress in developing new quantum Monte Carlo methods for simulating strongly correlated electron systems. We then present a summary of our ongoing studies of the Hubbard model with these methods, including the ground-state constrained path Monte Carlo method and a new nite-temperature method. These methods make possible simulations at large system sizes and low temperatures. ...

Nonequilibrium Quantum Breakdown in a Strongly Correlated Electron System

During the past decades, there has been an increasing fascination and surprises with diverse quantum many-body effects. With the magical touch of interaction a simple electron system may assume insulating, metallic, magnetic or superconducting states according as the control parameters are changed. Strongly correlated electron systems, as exemplified by the high-Tc superconductors and their hos...

Solving strongly correlated electron models on a quantum computer

One of the main applications of future quantum computers will be the simulation of quantum models. While the evolution of a quantum state under a Hamiltonian is straightforward (if sometimes expensive), using quantum computers to determine the ground state phase diagram of a quantum model and the properties of its phases is more involved. Using the Hubbard model as a prototypical example, we he...
