Raman-scattering study of the phonon dispersion in twisted bi-layer graphene

, 2013
Bi-layer graphene with a twist angle \theta\ between the layers generates a superlattice structure known as Moir\'{e} pattern. This superlattice provides a \theta-dependent q wavevector that activates phonons in the interior of the Brillouin zone.

Protected nodal electron pocket from multiple-Q ordering in underdoped high temperature superconductors

, 2011
A multiple wavevector (Q) reconstruction of the Fermi surface is shown to yield a profoundly different electronic structure to that characteristic of single wavevector reconstruction, despite their proximity in energy.

Improvement of gain and spatial resolution for impulsive stimulated Brillouin scattering microscopy

Photoacoustics
Brillouin microscopy has been widely used in the mechanical imaging of cells and tissues, and the signal-to-noise (SNR) ratio limits the spectral integration time.

Room temperature chiral magnetic skyrmion in ultrathin magnetic nanostructures

, 2016
Magnetic skyrmions are chiral spin structures with a whirling configuration. Their topological properties, nanometer size and the fact that they can be moved by small current densities have opened a new paradigm for the manipulation of magnetisation at ...

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Spectral Phasor Analysis for Brillouin Microspectroscopy

Frontiers in Physics, 2019
Brillouin Light Scattering (BLS) spectroscopy allows for the all-optical measurement of the hypersonic velocities in a sample, from which one can extract high-frequency elastic moduli. Recent advances in high resolution optical imaging spectrometers have

Domain wall-based spin-Hall nano-oscillators

, 2018
In the last decade, two revolutionary concepts in nano magnetism emerged from research for storage technologies and advanced information processing. The first suggests the use of magnetic domain walls (DWs) in ferromagnetic nanowires to permanently store
