Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing inspiration …

Pathogens hitting the plant cell wall is the first impetus that triggers the phenylpropanoid
pathway for plant defense. The phenylpropanoid pathway bifurcates into the production of an …

Topological photonics emerged as a novel route to engineer the flow of light. Topologically
protected photonic edge modes, which are supported at the perimeters of topologically …

Objectives This study aims to analyze the incidence of Post-acute COVID-19 syndrome (PCS)
and its components, and to evaluate the acute infection phase associated risk factors. …

Superfluidity, the ability of a quantum fluid to flow without friction, is one of the most spectacular
phenomena occurring in degenerate gases of interacting bosons. Since its first discovery …

A quantum fluid passing an obstacle behaves differently from a classical one. When the flow
is slow enough, the quantum gas enters a superfluid regime, and neither whirlpools nor …

Integrated switching devices comprise the building blocks of ultrafast optical signal
processing 1 , 2 . As the next stage following intensity switching 1 , 3 , 4 , circular polarization …

The coupling of two macroscopic quantum states through a tunnel barrier gives rise to Josephson
phenomena 1 such as Rabi oscillations 2 , the ac and dc effects 3 , or macroscopic self…

Semiconductor microcavities offer unique systems in which to investigate the physics of
weakly interacting bosons. Their elementary excitations, polaritons—mixtures of excitons and …

We use coupled micropillars etched out of a semiconductor microcavity to engineer a spin-orbit
Hamiltonian for photons and polaritons in a microstructure. The coupling between the …
