Optical conductivity of a quantum electron gas in a Sierpinski carpet

Edo van Veen, Andrea Tomadin, Marco Polini +2

Recent advances in nanofabrication methods have made it possible to create complex two-dimensional artificial structures, such as fractals, where electrons can be confined. The opt…

Acoustic Dirac degeneracy and topological phase transitions realized by rotating scatterers

Xinhua Wen, Chunyin Qiu, Jiuyang Lu +3

The artificial crystals for classical waves provide a good platform to explore the topological physics proposed originally in condensed matter systems. In this paper, acoustic Dira…

Magnetically Activated Rotational Vacuum Friction

Deng Pan, Hongxing Xu, F. Javier García de Abajo

We predict the existence of a torque acting on an isotropic neutral nanosphere activated by a static magnetic field when the particle temperature differs from the surrounding vacuu…

Interaction-driven Quantum Anomalous Hall Effect in Halogenated Hematite Nanosheets

Qi-Feng Liang, Jian Zhou, Rui Yu +2

Based on first-principle calculations and model analysis, we show that the quantum anomalous Hall (QAH) insulating phase can be realized in the functionalized hematite (…
