Superfluidity as a research area investigates quantum condensed phases of matter that exhibit frictionless flow, quantized circulation, and macroscopic quantum coherence, primarily in systems such as liquid helium-4, helium-3, ultracold atomic gases, and exciton–polariton condensates. The field focuses on understanding the microscopic mechanisms underlying Bose–Einstein condensation and fermionic pairing, the role of symmetry breaking and topological order, and the dynamics of quantized vortices and collective excitations. Research integrates many-body theory, quantum field methods, and precision low-temperature experiments to probe phase diagrams, critical phenomena, transport properties, and potential applications in quantum technologies and precision metrology.
In a recent study, researchers made a significant observation of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a 2D dipolar gas of ultracold atoms. This work marks a milestone in understanding how 2D superfluids ...

Data collected by the SAMURAI spectrometer at RIKEN's RI Beam Factory (RIBF) in Japan recently led to the detection of a rare fluorine (F) isotope, known as 30F. This has opened interesting possibilities for the study of ...
Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls.
