Pseudo-superconducting-diode effect in ferroelectric Josephson junctions
Yaozu Tang, Nienke ten Haaf, Artem Bondarenko +2
The superconducting diode effect (SDE), characterized by unequal critical supercurrents in opposite current directions, enables supercurrent rectification. We propose a magnetic-fi…
Quantum-Material Josephson Junctions: Unconventional Barriers, Emerging Functionality
Kathryn A. Pitton, Michiel P. Dubbelman, Trent M. Kyrk +5
Josephson junctions translate quantum phase coherence into an electrical response and underpin superconducting sensors and quantum circuits. In conventional junctions, the barrier…
From strong to weak correlations in breathing-mode kagome van der Waals materials: Nb(F,Cl,Br,I) as a robust and versatile platform for many-body engineering
Joost Aretz, Sergii Grytsiuk, Xiaojing Liu +12
By combining ab initio downfolding with cluster dynamical mean-field theory, we study the degree of correlations in monolayer, bilayer and bulk breathing-mode kagome van der Waals…
Anomalous refractive index modulation and giant birefringence in 2D ferrielectric CuInPS
Houssam El Mrabet Haje, Roald J. H. van der Kolk, Trent M. Kyrk +1
2D ferroelectric (FE) materials have opened new opportunities in non-volatile memories, computation and non-linear optics due to their robust polarization in the ultra-thin limit a…
Roadmap on Quantum Magnetic Materials
Antonija GrubiÅ¡iÄ-Äabo, Marcos H. D. Guimarães, Dmytro Afanasiev +36
Fundamental research on two-dimensional (2D) magnetic systems based on van der Waals materials has been gaining traction rapidly since their recent discovery. With the increase of…
Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
