Topological Quantum Computation Based on Chiral Majorana Fermions
Biao Lian, Xiao-Qi Sun, Abolhassan Vaezi +2
Chiral Majorana fermion is a massless self-conjugate fermion which can arise as the edge state of certain two-dimensonal topological matters. It has been theoretically predicted an…
Superconductivity in Few-Layer Stanene
Menghan Liao, Yunyi Zang, Zhaoyong Guan +11
A single atomic slice of α-tin-stanene-has been predicted to host quantum spin Hall effect at room temperature, offering an ideal platform to study low-dimensional and topological…
Realizing an Epitaxial Stanene with an Insulating Bandgap
Yunyi Zang, Tian Jiang, Yan Gong +12
Stanene, a single atomic layer of Sn in a honeycomb lattice, is predicted a candidate wide bandgap two-dimensional (2D) topological insulator and can host intriguing topological st…
Gated Tuned Superconductivity and Phonon Softening in Mono- and Bilayer MoS
Yajun Fu, Erfu Liu, Hongtao Yuan +16
Superconductors at the atomic two-dimensional (2D) limit are the focus of an enduring fascination in the condensed matter community. This is because, with reduced dimensions, the e…
Quantum phase transition of chiral Majorana fermion in the presence of disorder
Biao Lian, Jing Wang, Xiao-Qi Sun +2
We study the quantum phase transitions of a disordered two-dimensional quantum anomalous Hall insulator with -wave superconducting proximity, which are governed by the percolati…
Magnetic order induces symmetry breaking in the single crystalline orthorhombic CuMnAs semimetal
Eve Emmanouilidou, Huibo Cao, Peizhe Tang +7
Recently, orthorhombic CuMnAs has been proposed to be a magnetic material where topological fermions exist around the Fermi level. Here we report the magnetic structure of the orth…
