Topological defects as relics of emergent continuous symmetry and Higgs condensation of disorder in ferroelectrics
Shi-Zeng Lin, Xueyun Wang, Yoshitomo Kamiya +9
Lars Onsager and Richard Feynman envisioned that the three-dimensional (3D) superfluid-to-normal transition in He occurs through the proliferation of vortices. This proce…
Unsupervised Feature Analysis with Class Margin Optimization
Sen Wang, Feiping Nie, Xiaojun Chang +3
Unsupervised feature selection has been always attracting research attention in the communities of machine learning and data mining for decades. In this paper, we propose an unsupe…
Quadratic unitary Cayley graphs of finite commutative rings
Xiaogang Liu, Sanming Zhou
The purpose of this paper is to study spectral properties of a family of Cayley graphs on finite commutative rings. Let be such a ring and its set of units. Let $Q_R…
Electronic and magnetic properties of off-stoichiometric CoMnSi/MgO interfaces studied by x-ray magnetic circular dichroism
V. R. Singh, V. K. Verma, K. Ishigami +8
We have studied the electronic and magnetic states of Co and Mn atoms at the interface of the CoMnSi (CMS)/MgO (=0.69, 0.99, 1.15 and 1.29) magnetic tunnel junc…
Distinct itinerant spin-density waves and local-moment antiferromagnetism in an intermetallic ErPdSi single crystal
Hai-Feng Li, Chongde Cao, Andrew Wildes +8
Identifying the nature of magnetism, itinerant or localized, remains a major challenge in condensed-matter science. Purely localized moments appear only in magnetic insulators, whe…
Silicene Nanomesh
Feng Pan, Yangyang Wang, Kaili Jiang +8
Similar to graphene, zero band gap limits the application of silicene in nanoelectronics despite of its high carrier mobility. By using first-principles calculations, we reveal tha…
