A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations
Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying systems comprised of several.....»»
Extreme weather forecasts: Algorithm "nudges" existing climate simulations closer to future reality
To assess a community's risk of extreme weather, policymakers rely first on global climate models that can be run decades, and even centuries, forward in time, but only at a coarse resolution. These models might be used to gauge, for instance, future.....»»
