About agdelma

Dr. Del Maestro is an Associate Professor of Physics at the University of Vermont studying how collective and cooperative states of matter emerge in quantum many-body systems. He employs the tools of theoretical physics to study phase transitions, dimensional crossover and entanglement in quantum fluids, ultra-cold bosonic gases, superconductors and topological states of matter. This includes using quantum field theory in tandem with the development of novel high-performance computational algorithms for the study of strongly interacting quantum matter.

Superfluid helium and black holes

An entangled connection

At low temperatures, helium—the same substance that makes balloons float—becomes a special type of liquid known as a superfluid, which has zero viscosity. It's like the anti-molasses! The properties of superfluids are governed by the laws of quantum mechanics. More specifically, the atoms in superfluid helium are “entangled” with each other, allowing them to share information and influence each other’s behavior in ways that are totally foreign to our everyday experience, and which Einstein famously described as "spooky action at a distance." Better still, scientists have recently discovered that the law controlling entanglement between different parts of a helium superfluid is the same as that governing the exotic behavior of black holes in outer space.
