The foundation of atomic physics is the arsenal of spectroscopic tools to probe individual
atoms and molecules with astounding precision. With the advent of ultracold quantum …

This article summarizes some of the relevant features exhibited by binary mixtures of Bose–
Einstein condensates in the presence of coherent coupling at zero temperature. The …

Topological gauge theories describe the low-energy properties of certain strongly correlated
quantum systems through effective weakly interacting models,. A prime example is the …

Dark energy and dark matter constitute 95% of the observable Universe. Yet the physical
nature of these two phenomena remains a mystery. Einstein suggested a long-forgotten …

Topological bound states in the continuum are confined wave-mechanical objects that offer
advantageous ways to enhance light–matter interactions in compact photonic devices. In …

Dispersion engineering is a powerful and versatile tool that can vary the speed of light
signals and induce negative-mass effects in the dynamics of particles and quasiparticles …

Modulational instabilities play a key role in a wide range of nonlinear optical phenomena,
leading, eg, to the formation of spatial and temporal solitons, rogue waves, and chaotic …

In a trapped spin-1/2 Bose-Einstein condensate with miscible interactions, a two-
dimensional spin-orbit coupling can introduce an unconventional spatial separation …

We introduce a vector form of the cubic complex Ginzburg-Landau equation describing the
dynamics of dissipative solitons in the two-component helicoidal spin-orbit coupled open …

By inducing a Raman transition using a pair of Gaussian and Laguerre-Gaussian laser
beams, we realize a Rb 87 condensate whose orbital angular momentum (OAM) and its …
