A hybrid optoelectronic Mott insulator
Henry Navarro, Javier del Valle, Yoav Kalcheim +11
The coupling of electronic degrees of freedom in materials to create hybridized functionalities is a holy grail of modern condensed matter physics that may produce novel mechanisms…
Controlling Metal-Insulator Transitions in Vanadium Oxide Thin Films by Modifying Oxygen Stoichiometry
Min-Han Lee, Yoav Kalcheim, Javier del Valle +1
Vanadium oxides are strongly correlated materials which display metal-insulator transitions as well as various structural and magnetic properties that depend heavily on oxygen stoi…
A caloritronics-based Mott neuristor
Javier del Valle, Pavel Salev, Yoav Kalcheim +1
Machine learning imitates the basic features of biological neural networks to efficiently perform tasks such as pattern recognition. This has been mostly achieved at a software lev…
The magnetic origin of the metal-insulator transition in V2O3: Mott meets Slater
J. Trastoy, A. Camjayi, J. del Valle +6
Despite decades of experimental and theoretical efforts, the origin of metal-insulator transitions (MIT) in strongly-correlated materials is one of the main longstanding problems i…
Magnetic order and disorder in nanomagnets probed by superconducting vortices
V. Rollano, J. del Valle, A. Gomez +8
We have studied two nanomagnet systems with strong (Co/Pd multilayers) and weak (NdCo alloy films) stray magnetic fields by probing the out-of-plane magnetic states with supercondu…
