Práticas de investigação partilhada ou como interpelar as fronteiras disciplinares em música: perspetivas a partir de (uma) etnomusicologia

Este texto resulta de um desafio: o de discorrer sobre a importância da prática de investigação no desenvolvimento do conhecimento em música a partir da minha experiência como etnomusicóloga. É, no entanto, produzido no&...

Multipolar boson stars: macroscopic Bose-Einstein condensates akin to hydrogen orbitals

Boson stars are often described as macroscopic Bose-Einstein condensates. By accommodating large numbers of bosons in the same quantum state, they materialize macroscopically the intangible probability density cloud of a single&#...

Spin-induced scalarized black holes

It was recently shown that a scalar field suitably coupled to the Gauss-Bonnet invariant $\mathcal{G}$ can undergo a spin-induced linear tachyonic instability near a Kerr black hole. This instability appears only once&#...

Two-step multiuser equalization for hybrid mmWave massive MIMO GFDM systems

Although millimeter-wave (mmWave) and massive multiple input multiple output (mMIMO) can be considered as promising technologies for future mobile communications (beyond 5G or 6G), some hardware limitations limit their applicability. T...
