We present experimental results obtained with a model experimental system dedicated to the study of 2D structures and phase transitions. The system is composed of a monolayer of millimetric soft ferromagnetic beads confined in a 2D horizontal cell. The beads are immersed in a vertical and homogeneous magnetic field inducing magnetic dipole-dipole i...

We propose to realize one-dimensional topological phases protected by SU(N) symmetry using alkali or alkaline-earth atoms loaded into a bichromatic optical lattice. We derive a realistic model for this system and investigate it theoretically. Depending on the parity of N, two different classes of symmetry-protected topological (SPT) phases are stab...

The pyrite mineral MnS_{2} was recently shown to undergo a giant pressure-induced volume collapse at âˆ¼ 12 GPa, via a disordered intermediate phase. The high pressure arsenopyrite phase is stabilised by metal-metal bonding, a mechanism now shown to be ubiquitous for Mn^{2+} chalcogenides. Here we report a spectroscopic investigation of this transition up ...

While neutron imaging is a well-established technique for investigations of inner structures and processes in materials, complex systems, and devices, the utilization of polarized neutron beams to visualize magnetic phenomena has been introduced only about a decade ago. In contrast to neutron scattering studies, where the interaction of the neutron...

The behaviors of ferromagnetic transition metals of the first period: Fe, Co and Ni are examined within density functional theory calculations in two dimensional carbon extended networks using model structure LiC6. Around geometry optimized structures, the energy-volume equations of states considering non magnetic and spin polarized configurations ...
