Morphology-induced spectral modification of self-assembled WS2 pyramids

Posted by klaurent Delft

Kavli Affiliate: Sonia Conesa-Boj | Summary:Due to their intriguing optical properties, including stable and chiral excitons, two-dimensional transition metal dichalcogenides (2D-TMDs) hold the promise of applications in nanophotonics. Chemical vapor deposition (CVD) techniques offer a platform to fabricate and design nanostructures with diverse geometries. However, the more exotic the grown nanogeometry, the less is known […]

Initial Design of a W-band Superconducting Kinetic Inductance Qubit (Kineticon)

Posted by klaurent Caltech

Kavli Affiliate: Mohammad Mirhosseini | Summary:Superconducting qubits are widely used in quantum computing research and industry. We describe a superconducting kinetic inductance qubit (and introduce the term Kineticon to describe it) operating at W-band frequencies with a nonlinear nanowire section that provides the anharmonicity required for two distinct quantum energy states. Operating the qubits at […]

Kavli Affiliate: Sol M. Gruner | Summary:Orbital angular momentum and torque transfer play central roles in a wide range of magnetic textures and devices including skyrmions and spin-torque electronics(1-4). Analogous topological structures are now also being explored in ferroelectrics, including polarization vortex arrays in ferroelectric/dielectric superlattices(5). Unlike magnetic toroidal order, electric toroidal order does not […]
