FAMU-FSU professor will study superfluid helium with $1.25M grant from Gordon and Betty Moore Foundation

When the temperature of matter approaches absolute zero, a different type of physics takes over. Instead of classical physics — the physics you learned about in high school — quantum physics governs its behavior. For example, helium is typically a gas, but when an isotope of helium is cooled to very low temperatures, it becomes […]

FSU researchers expand understanding of vortex spread in superfluids

An international team of scientists featuring Florida State University researchers has developed a model that predicts the spread of vortices in so-called superfluids, work that provides new insight into the physics that govern turbulence in quantum fluid systems such as superfluid neutron stars. In a paper published in Physical Review Letters, the researchers created a […]

Building a better quantum bit: New qubit breakthrough could transform quantum computing

You are no doubt viewing this article on a digital device whose basic unit of information is the bit, either 0 or 1. Scientists worldwide are racing to develop a new kind of computer based on the use of quantum bits, or qubits, which can simultaneously be 0 and 1 and could one day solve […]

NASA selects FAMU-FSU College of Engineering to help develop sustainable aviation system

Researchers at the FAMU-FSU College of Engineering will help NASA develop the future of sustainable aviation as part of a five-year, $10 million project. FAMU-FSU Professor of Mechanical Engineering Louis Cattafesta will lead a team in developing a hybrid electric power system that uses turboelectric generators and fuel cells. The system is powered by hydrogen […]

Low-gravity simulator design developed by FAMU-FSU College of Engineering researchers offers new avenues for space research

As humanity continues its exploration of the universe, the low-gravity environment of space presents unusual challenges for scientists and engineers. Researchers at the FAMU-FSU College of Engineering and the Florida State University-headquartered National High Magnetic Field Laboratory have developed a new tool to help meet that challenge — a novel design for a low-gravity simulator […]

Engineering researchers develop new explanation for formation of vortices in 2D superfluid

Researchers at the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory have new insight about the formation of vortices in a type of quantum fluid, work that could help our comprehension of the physics mystery of how vortex clusters form and provide valuable understanding into the atmospheric swirling motion on planets such […]

Engineering researcher gets NSF award for 3D imaging technology to advance quantum fluid research

Superfluids are one of the 20th century’s most fascinating and important discoveries. Their study is the basis of Nobel Prize-winning work, and they hold promise for better electricity transmission and may even help answer the secrets of the universe with their mysterious “quantum fluid” properties. Wei Guo, an associate professor of mechanical engineering at the […]

FSU engineering researchers visualize the motion of vortices in superfluid turbulence

Nobel laureate in physics Richard Feynman once described turbulence as “the most important unsolved problem of classical physics.” Understanding turbulence in classical fluids like water and air is difficult partly because of the challenge in identifying the vortices swirling within those fluids. Locating vortex tubes and tracking their motion could greatly simplify the modeling of […]
