Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot
Xunyao Luo, Xander Peetroons, Tsung-Yeh Yang +27
Electron spin resonance spectroscopy (ESR) of a single electron in planar Si-MOS quantum dot is reported in the vicinity of a valley level anti-crossing. A number of one and two-ph…
Hidden Zeeman Field in Odd-Parity Magnets: An Ideal Platform for Topological Superconductivity
Xun-Jiang Luo, Zi-Ting Sun, Xilin Feng +2
Odd-parity magnets (OPMs) have emerged as a fundamental class of unconventional magnetisms, characterized by time-reversal-preserving non-relativistic spin splitting (NSS). Despite…
Spin Group Symmetry Criteria For Unconventional Magnetism
Xun-Jiang Luo, Jin-Xin Hu, Mengli Hu +1
Unconventional magnetism has typically been classified into two fundamental classes: even-parity magnets (EPMs) and odd-parity magnets (OPMs). These two classes exhibit identical a…
Signature of gate tunable superconducting network in twisted bilayer graphene
Yingbo Wang, Yingzhuo Han, Lu Cao +14
Twisted van der Waals materials provide a tunable platform for investigating two-dimensional superconductivity and quantum phases. Using spectra-imaging scanning tunneling microsco…
Surface-dependent Majorana vortex phases in topological crystalline insulators
Xun-Jiang Luo, Xiao-Hong Pan, Yilin Shi +1
The topological crystalline insulator SnTe exhibits two types of surface Dirac cones: one located at non-time-reversal-invariant momenta on the (001) and (110) surfaces, and the ot…
Family of third-order topological insulators from Su-Schrieffer-Heeger stacking
Xun-Jiang Luo, Jia-Zheng Li, Meng Xiao +1
We construct a family of chiral symmetry-protected third-order topological insulators by stacking Su-Schrieffer-Heeger (SSH) chains and provide a unified topological characterizati…
