Asymmetric Localization by Second Harmonic Generation
H. Ghaemi-Dizicheh, A. Targholizadeh, B. Feng +1
We introduce a nonlinear photonic system that enables asymmetric localization and unidirectional transfer of an electromagnetic wave through the second harmonic generation process.…
Discovery of Weyl nodal lines in a single-layer ferromagnet
B. Feng, R. -W. Zhang, Y. Feng +9
Two-dimensional (2D) materials have attracted great attention and spurred rapid development in both fundamental research and device applications. The search for exotic physical pro…
Superstructure-induced splitting of Dirac cones in silicene
B. Feng, H. Zhou, Y. Feng +8
Atomic scale engineering of two-dimensional materials could create devices with rich physical and chemical properties. External periodic potentials can enable the manipulation of t…
Quantum Reflection above the Classical Radiation-reaction Barrier in the QED Regime
X. S. Geng, L. L. Ji, B. F. Shen +5
The colliding between an ultra-intense laser pulse with a high energy electron beam is not only an important source for high-brightness gamma-rays but also a powerful approach to e…
Radiative deflection by spin effect in the quantum radiation-reaction regime
X. S. Geng, L. L. Ji, B. F. Shen +11
The colliding between ultra-relativistic electrons and an ultra-intense laser pulse is a powerful approach to testify the physics in strong-field QED regime. By considering spin-de…
Alkali-metal induced band structure deformation investigated by angle-resolved photoemission spectroscopy and first-principles calculations
S. Ito, B. Feng, M. Arita +10
Alkali-metal adsorption on the surface of materials is widely used for in situ surface electron doping, particularly for observing unoccupied band structures by angle-resolved phot…
Proving Nontrivial Topology of Pure Bismuth by Quantum Confinement
S. Ito, B. Feng, M. Arita +13
The topology of pure Bi is controversial because of its very small (10 meV) band gap. Here we perform high-resolution angle-resolved photoelectron spectroscopy measurements s…
Exponential stability for a nonlinear porous-elastic system with delay
M. J. Dos Santos, C. A. Raposo, L. G. R. Miranda +1
In this work, we consider the existence of global solution and the exponential decay of a nonlinear porous elastic system with time delay. The nonlinear term as well as the delay a…
Interface electronic structure at the topological insulator - ferrimagnetic insulator junction
Y. Kubota, K. Murata, J. Miyawaki +15
An interface electron state at the junction between a three-dimensional topological insulator (TI) film of Bi2Se3 and a ferrimagnetic insulator film of Y3Fe5O12 (YIG) was investiga…
Surface-state Coulomb repulsion accelerates a metal-insulator transition in topological semimetal nanofilms
S. Ito, M. Arita, J. Haruyama +11
The emergence of quantization at the nanoscale, the quantum size effect (QSE), allows flexible control of matter and is a rich source of advanced functionalities. A QSE-induced tra…
