Superfluidity - Wikipedia
Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without any loss of kinetic energy. When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium (helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures.
How superfluids work in-depth | Description, Example & Application
2023年5月17日 · Learn how superfluids work, from the role of quantum mechanics to their potential applications in fields like fluid dynamics and energy production. How Do Superfluids Work? Superfluidity is a phenomenon that occurs when a fluid is cooled to extremely low temperatures, close to absolute zero (-273.15°C or -459.67°F), and it loses all its ...
Superfluidity Definition and Examples - Science Notes and Projects
2022年2月9日 · By definition, superfluidity is the zero viscosity flow of a fluid, such as a liquid or gas. In physics, superfluidity is a property of fluids where they have zero viscosity or are frictionless. A substance displaying this property is superfluid. Superfluids flow …
Superfluid: The importance of Liquid Helium and its applications
2021年4月28日 · What is Liquid Helium and why is it called a Superfluid? “Liquid Helium”, at standard atmospheric pressures, refers to the physical state of helium at very low temperatures. When Helium is in this liquid state, we refer to it as “superfluid”. A superfluid is a state in which matter acts like a non-viscosity fluid.
densed matter physics who are interested in high-energy applications of their field and a relativistic field-theoretical formalism they usually do not employ. And, most importantly, this course is intended for advanced undergraduate students, graduate students, and researchers who simply want to understand what superfluidity is and
[1404.1284] Introduction to superfluidity -- Field-theoretical approach ...
2014年4月4日 · In this pedagogical introduction, I discuss theoretical aspects of superfluidity and superconductivity, mostly using a field-theoretical formalism. While the emphasis is on general concepts and mechanisms behind superfluidity, I also discuss various applications in low-energy and high-energy physics.

SUPERFLUIDITY - CERN
In this paper we shall concentrate on the simplest superfluid, formed from liquid 4He. Liquid 4He, in either its normal phase or its superfluid phase, is used as a coolant in practical applications: most commonly in superconducting magnets and SQUID systems. It is not practicable to include in this paper a complete set of references.
Superfluidity - New World Encyclopedia
Recently, researchers have developed several applications for superfluids. For instance, they have been used as specialized solvents (quantum solvents) in spectroscopy, as agents to trap and dramatically reduce the speed of light, and as materials needed in high-precision gyroscopes .
Applications of Superfluid Helium in Large-Scale Superconducting ...
