The logic of contextuality
Samson Abramsky, Rui Soares Barbosa
Contextuality is a key signature of quantum non-classicality, which has been shown to play a central role in enabling quantum advantage for a wide range of information-processing a…
Bursting and excitability in neuromorphic resonant tunneling diodes
Ignacio Ortega, Oreste Piro, Bruno Romeira +1
We study in this paper the dynamics of quantum nanoelectronic resonant tunneling diodes (RTDs) as excitable neuromorphic spike generators. We disclose the mechanisms by which the R…
A colloquium on the variational method applied to excitons in 2D materials
M. F. C. Martins Quintela, N. M. R. Peres
In this colloquium, we review the research on excitons in van der Waals heterostructures from the point of view of variational calculations. We first make a presentation of the cur…
How additive manufacturing can boost the bioactivity of baked functional foods
Sara M Oliveira, Alice Gruppi, Marta V. Vieira +6
The antioxidant activity of baked foods is of utmost interest when envisioning enhancing their health benefits. Incorporating functional ingredients is challenging since their bioa…
Highly Confined In-plane Exciton-Polaritons in Monolayer Semiconductors
Itai Epstein, Andre J. Chaves, Daniel A. Rhodes +7
2D materials support unique excitations of quasi-particles that consist of a material excitation and photons called polaritons. Especially interesting are in-plane propagating pola…
Beyond the gyrotropic motion: dynamic C-state in vortex spin torque oscillators
Steffen Wittrock, Philippe Talatchian, Miguel Romera Rabasa +9
In the present study, we investigate a dynamical mode beyond the gyrotropic (G) motion of a magnetic vortex core in a confined magnetic disk of a nano-pillar spin torque nano oscil…
