Mott physics in the multiflavored age

Frédéric Mila

The multiflavor Mott insulators, whose local Hilbert space consists of multiple degrees of freedom, occur widely in both quantum materials and ultracold atom systems. This Comment recommends the review article by Chen and Wu that is, to the author's knowle ...

Quantum Transport in 40-nm MOSFETs a Deep-Cryogenic Temperatures

Edoardo Charbon, Andrea Ruffino, Yatao Peng

In this letter, we characterize the electrical properties of commercial bulk 40-nm MOSFETs at room and deep cryogenic temperatures, with a focus on quantum information processing (QIP) applications. At 50 mK, the devices operate as classical FETs or quantu ...

Template-Assisted Scalable Nanowire Networks

Anna Fontcuberta i Morral, Lucas Güniat, Gözde Tütüncüoglu, Martin George Friedl, Heidi Andrea Potts, Wonjong Kim, Mahdi Zamani, Vladimir Dubrovskii, Sara Marti Sanchez

Topological qubits based on Majorana Fermions have the potential to revolutionize the emerging field of quantum computing by making information processing significantly more robust to decoherence. Nanowires are a promising medium for hosting these kinds of ...

Towards defect-free 1-D GaAs/AlGaAs heterostructures based on GaAs nanomembranes

Anna Fontcuberta i Morral, Federico Matteini, Gözde Tütüncüoglu, Heidi Andrea Potts, Davide Deiana

We demonstrate the growth of defect-free zinc-blende GaAs nanomembranes by molecular beam epitaxy. Our growth studies indicate a strong impact of As-4 re-emission and shadowing in the growth rate of the structures. The highest aspect ratio structures are o ...

Bandgap engineering in a nanowire: self-assembled 0, 1 and 2D quantum structures

Inherent to the nanowire morphology is the exciting possibility of fabricating materials organized at the nanoscale in three dimensions. Composition and structure can be varied along and across the nanowire, as well as within coaxial shells. This opens up ...

Elsevier2013

The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...
