Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.Excitons in biased bilayer graphene are electrically tunable excitations in the mid‐infrared (MIR) spectrum, where optical transitions are typically scarce. In this work, it is demonstrated that when the bilayer is encapsulated in hexagonal‐boron‐nitride (hBN)—a material supporting optical phonons and hyperbolic‐phonon‐polaritons (HPhPs) in the MIR—the

First and second sound of a unitary Fermi gas in highly oblate harmonic traps
New Journal of Physics, 2014 We theoretically investigate first and second sound modes of a unitary Fermi gas trapped in a highly oblate harmonic trap at finite temperatures. Following the idea by Stringari and co-workers (2010 Phys. Rev. Lett.

, 2010 Superfluidity, the ability of a fluid to move without dissipation, is one of the most spectacular manifestations of the quantum nature of matter. We explore here the possibility of superfluid motion of light.

Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.Abstract INTRODUCTION Accurate identification of individuals at risk for cognitive decline is critical for treatment planning and trial enrichment strategies. We evaluated the combined utility of plasma phosphorylated tau at threonine 217 (p‐tau217), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP) in predicting domain ...

, 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.

Superfluid spin transport in magnetically ordered solids
, 2020 The paper reviews the theory of the long-distance spin superfluid transport in solid ferro- and antiferromagnets based on the analysis of the topology, the Landau criterion, and phase slips.

Supercurrents and Tunneling in Massive Many‐Vortex Necklaces and Star‐Lattices
Annalen der Physik, Volume 537, Issue 12, December 2025.It is numerically shown how massive many‐vortex systems, in a mixture of Bose–Einstein condensates, can host the bosonic tunneling of the infilling component in an almost‐periodic way when the vortices are organized in necklaces or star‐lattices. The purpose is to explore the conditions for the onset of Josephson supercurrents in rotating many‐vortex ...

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions
Laser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

Self-consistent approach for Bose-condensed atoms in optical lattices
Condensed Matter Physics, 2013 Bose atoms in optical lattices are considered at low temperatures and weak interactions, when Bose-Einstein condensate is formed. A self-consistent approach, based on the use of a representative statistical ensemble, is employed, guaranteeing a gapless ...
