A quantum simulator is a type of quantum computer that controls the interactions between
quantum bits (or qubits) in a way that can be mapped to certain quantum many-body …

Spontaneous symmetry breaking is a fundamental concept in many areas of physics,
including cosmology, particle physics and condensed matter. An example is the breaking of …

Quantum computers can solve certain problems more efficiently than any possible
conventional computer. Small quantum algorithms have been demonstrated on multiple …

When a system thermalizes it loses all memory of its initial conditions. Even within a closed
quantum system, subsystems usually thermalize using the rest of the system as a heat bath …

The routine application of Csp3-hybridized nucleophiles in cross-coupling reactions remains
an unsolved challenge in organic chemistry. The sluggish transmetalation rates observed for …

Extending the framework of statistical physics to the nonequilibrium setting has led to the
discovery of previously unidentified phases of matter, often catalyzed by periodic driving …
