Probing superfluidity in a quasi two-dimensional Bose gas through its local dynamics

New Journal of Physics, 2016
We report direct evidence of superfluidity in a quasi two-dimensional Bose gas by observing its dynamical response to a collective excitation, the scissors mode.

Dark Matter Superfluidity

, 2016
In this talk I summarize a novel framework that unifies the stunning success of MOND on galactic scales with the triumph of the $\Lambda$CDM model on cosmological scales. This is achieved through the rich and well-studied physics of superfluidity.

Optically Selective Photomask Based on Field‐Induced Periodic Defect Arrays in Ferroelectric Nematics

Advanced Optical Materials, Volume 14, Issue 12, 25 March 2026.
Field‐induced periodic defect patterns in the ferroelectric nematic liquid crystal phase act as optically selective photomasks. Created in the liquid crystal cells with bare electrodes, their periodicity is controlled by the applied frequency and cell gap. When used as photomasks, these patterns modulate transmitted light, whose spatial characteristics

Evidence of Gapless Superfluidity in MXB 1659-29 With and Without Late Time Cooling

Universe
The interpretation of the thermal relaxation of some transiently accreting neutron stars in quasipersistent soft X-ray transients, especially MXB 1659-29, has been found to be challenging within the traditional deep crustal heating paradigm.

Superfluidity and Stabilities of a Bose-Einstein condensate with periodically modulated interatomic interaction

, 2013
We study theoretically the superfluidity and stability of a Bose-Einstein condensate (BEC) whose interatomic scattering length is periodically modulated with optical Feshbach resonance.

Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

Nano Select, Volume 7, Issue 3, March 2026.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm

Superfluidity and effective mass of magnetoexcitons in topological insulator bilayers: Effect of inter-Landau-level Coulomb interaction

, 2012
The effective mass and superfluidity-normal phase transition temperature of magnetoexcitons in topological insulator bilayers are theoretically investigated.

Cover Feature: Advanced Electron Microscopy of Clusters Grown Inside Superfluid Helium Droplets: Advances, Challenges, and Perspectives (Small Struct. 3/2026)

Small Structures, Volume 7, Issue 3, March 2026.
Superfluid Helium Droplets Superfluid helium nanodroplets enable ultra‐clean fabrication of metallic clusters and nanowires that are difficult to access by other routes. In their Review (10.1002/sstr.202500586), Daniel Knez and co‐workers highlight aberration‐corrected STEM, EELS/EDX, and electron tomography for resolving structure, composition, and 3D
