Spin-Orbit Coupling Response Theory within the Oriented Spin Space Group Framework
Yuntian Liu, Xiaobing Chen, Yutong Yu +3
Spin-orbit coupling (SOC) plays a pivotal role in a broad range of phenomena in condensed matter physics. The recently developed spin space group theory offers a new perspective fo…
Automatic calculation of symmetry-adapted tensors under spin-group symmetry. STENSOR, a new tool of the Bilbao Crystallographic Server
Luis Elcoro, Jesus Etxebarria, J. Manuel Perez-Mato +1
We present STENSOR, a new computational tool integrated into the Bilbao Crystallographic Server, designed for the automatic calculation of symmetry-adapted tensors under spin group…
Symmetry Classification of Magnetic Orders using Oriented Spin Space Groups
Yuntian Liu, Xiaobing Chen, Yutong Yu +3
Magnetism has witnessed remarkable progress in recent decades, largely driven by its potential for next-generation storage devices. However, the classification of magnetic orders,…
Chiral ferroelectric nematic liquid crystals as materials for versatile laser devices
César L. Folcia, Josu Ortega, Teresa Sierra +2
We present a liquid-crystal laser device based on the chiral ferroelectric nematic phase (NF*). The laser medium is obtained by mixing a ferroelectric nematic material with a chira…
Second harmonic generation in anisotropic stratified media: A generalization of the Berreman method and its application to photonic materials
J. Ortega, C. L. Folcia, J. Etxebarria
We have developed a numerical method for calculating the second harmonic generation (SHG) generated by an anisotropic material whose optical properties present an arbitrary modulat…
Ferroelectric chiral nematic liquid crystals: New photonic materials with multiple bandgaps controllable by low electric fields
J. Ortega, C. L. Folcia, J. Etxebarria +1
We have carried out a spectroscopic study on a prototype ferroelectric nematic material (RM7343) doped with a non-polar chiral compound. The mixture presents two chiral nematic pha…
The ferroelectric nematic phase: An optimum liquid crystal candidate for nonlinear optics
C. L. Folcia, J. Ortega, R. Vidal +2
Materials that exhibit high nonlinear optical (NLO) susceptibilities are considered as promising candidates for a wide range of photonic and electronic applications. Here we argue…
Generalization of the Maier-Saupe theory to the ferroelectric nematic phase
J. Etxebarria, C. L. Folcia, J. Ortega
We present a generalization of the Maier-Saupe (MS) theory that incorporates the description of the ferroelectric nematic phase (NF) within its scope of application. The extension…
On the appearance of a Dirac delta term at the origin in the Schroedinger radial equation
J. Etxebarria
We revisit a recent discussion about the boundary condition at the origin in the Schroedinger radial equation for central potentials. Using a slight modification of the usual spher…
