Floquet Weyl Semimetal Induced by Off-Resonant Light
Rui Wang, Baigeng Wang, Rui Shen +3
We propose that a Floquet Weyl semimetal state can be induced in three-dimensional topological insulators, either nonmagnetic or magnetic, by the application of off-resonant light.…
Quantum computing through electron propagation in the edge states of quantum spin Hall systems
Wei Chen, Zheng-Yuan Xue, Z. D. Wang +2
We propose to implement quantum computing based on electronic spin qubits by controlling the propagation of the electron wave packets through the helical edge states of quantum spi…
All-electrically reading out and initializing topological qubits with quantum dots
Wei Chen, Zheng-Yuan Xue, Z. D. Wang +2
We analyze the reading and initialization of a topological qubit encoded by Majorana fermions in one-dimensional semiconducting nanowires, weakly coupled to a single level quantum…
Probing spin entanglement by gate-voltage-controlled interference of current correlation in quantum spin Hall insulators
Wei Chen, Z. D. Wang, R. Shen +1
We propose an entanglement detector composed of two quantum spin Hall insulators and a side gate deposited on one of the edge channels. For an ac gate voltage, the differential noi…
Magnetic response of mesoscopic rings: a quantum size effect
J. W. Ding, X. H. Yan, B. G. Wang +1
We analytically study the magnetic response of persistent current (PC) in normally non-interacting mesoscopic rings of bimodal potential with nearest neighboring interactions (t) a…
Topological phase transitions with and without energy gap closing
Yunyou Yang, Huichao Li, L. Sheng +3
Topological phase transitions in a three-dimensional (3D) topological insulator (TI) with an exchange field of strength are studied by calculating spin Chern numbers $C^\pm(k_z…
