Self‐Hybridized Exciton‐Polariton Photodetectors From Layered Metal‐Organic Chalcogenolates
Advanced Functional Materials, Volume 36, Issue 34, 27 April 2026.Self‐hybridized exciton‐polariton photodetectors are demonstrated using high refractive index mithrene, eliminating the need for top mirrors. This simplified architecture enables tunable sub‐bandgap photodetection via lower exciton‐polariton states and enhanced carrier transport through ultrafast polariton group velocities.

Generation of Anisotropic Second‐Harmonic Petal‐Like Beams with NbOBr2 Holograms
Advanced Photonics Research, Volume 7, Issue 4, April 2026.Highly anisotropic second‐harmonic petal‐like beams with different combinations of the topological charges of vortex beams are produced using ultrathin NbOBr2 holograms. These demonstrations provide a pathway toward the development of chip‐scale polarization‐sensitive functional optical devices for many applications.

Remarks on the Blow-Up Solutions for the Critical Gross-Pitaevskii Equation
Abstract and Applied Analysis, 2013 This paper is concerned with the blow-up solutions of the critical Gross-Pitaevskii equation, which models the Bose-Einstein condensate. The existence and qualitative properties of the minimal blow-up solutions are obtained.

Physical Review ResearchWe investigate the hollowing transition of a shell-shaped Bose-Einstein condensate using collective excitations. The shell is created using an immiscible dual-species Bose-Einstein condensate mixture, with its hollowness controlled by tuning the ...

ON THE VORTEX STRUCTURE IN TWO COMPONENT BOSE-EINSTEIN CONDENSATE
East European Journal of Physics, 2014 The vortex structure in a space-homogeneous Bose-Einstein condensate of two particle species with different masses has been studied. It is shown that the vortex structure in the two-component condensate is described by three dimensionless parameters ...

Interferometric Measurement of the Current-Phase Relationship of a Superfluid Weak Link
Physical Review X, 2014 Weak connections between superconductors or superfluids can differ from classical links due to quantum coherence, which allows flow without resistance.

Physical Review ResearchOpen dissipative systems of quantum fluids have been well studied numerically. In view of a complementary analytical description, we extend here the variational optimization method for Bose-Einstein condensates of closed systems to open-dissipative ...

Realizing and optimizing an atomtronic SQUID
New Journal of Physics, 2016 We demonstrate how a toroidal Bose–Einstein condensate with a movable barrier can be used to realize an atomtronic SQUID. The magnitude of the barrier height, which creates the analogue of an SNS junction, is of crucial importance, as well as its ramp-up
