Nonreciprocal Transport in Superconducting Diodes via Tailored Antidot Geometries

The superconducting diode effect (SDE) offers a transformative path toward dissipationless nonreciprocal electronics, yet a unified framework for controlling its microscopic origins remains elusive. Here, we demonstrate precision engineering of the SDE in niobium films by tailori...

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

ABSTRACT Thin dielectric films are known to show distinct colors, depending primarily on the film thickness. In the present article we show that a specialized thin film Fabry–Pérot resonator, that we name conductor–dielectric–conductor (CDC) matched cavity, appears grey when obse...

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

The intersection of topological photonics and nonlinear optics provides new opportunities for compact, tunable light sources. Here, we demonstrate even and odd harmonic generation, in the 6-10 THz range, in electrically driven micro-lasers by integrating a set of different topolo...

Cortical dynamics in Angelman syndrome: novel insights from a preclinical mouse model

Angelman syndrome (AS) is a neurogenetic disorder caused by the loss of function in the maternally inherited UBE3A gene, leading to a spectrum of symptoms that include developmental delays, intellectual disability, and motor impairments. While genetic and molecular mechanisms of...

Phenotyping iPSC-derived neurons from Angelman patients and partial rescue via JNK pathway inactivation

Angelman Syndrome (AS, MIM #105,830) is a rare neurodevelopmental disorder caused by imprinting defects, and it is marked by motor impairment, intellectual disability, speech limitations, and seizures. The condition arises due to the loss of function in neurons of the maternally-...
