Chiral zero modes in superconducting nanowires with Dresselhaus spin-orbit coupling
Hsien-chung Kao
Using chiral decomposition, we are able to find analytically the zero modes and the conditions for such modes to exist in the Kitaev ladder model and superconducting nanowires with…
Hybrid optical-electrical detection of donor electron spins with bound excitons in silicon
C. C. Lo, M. Urdampilleta, P. Ross +5
Electrical detection of spins is an essential tool in understanding the dynamics of spins in semiconductor devices, providing valuable insights for applications ranging from optoel…
Electric field control of spin-resolved edge states in graphene quantum nanorings
R. Farghadan, A. Saffarzadeh
The electric-field effect on the electronic and magnetic properties of triangular and hexagonal graphene quantum rings with zigzag edge termination is investigated by means of the…
Hyperfine Stark effect of shallow donors in silicon
G. Pica, G. Wolfowicz, M. Urdampilleta +9
We present a complete theoretical treatment of Stark effects in doped silicon, whose predictions are supported by experimental measurements. A multi-valley effective mass theory, d…
Magnetic edge states in Aharonov-Bohm graphene quantum rings
R. Farghadan, A. Saffarzadeh, E. Heidari Semiromi
The effect of electron-electron interaction on the electronic structure of Aharonov-Bohm (AB) graphene quantum rings (GQRs) is explored theoretically using the single-band tight-bi…
Chiral Symmetry Breaking and the Quantum Hall Effect in Monolayer Graphene
Bitan Roy, Malcolm P. Kennett, S. Das Sarma
Monolayer graphene in a strong magnetic field exhibits quantum Hall states at filling fractions and that are not explained within a picture of noninteracting elec…
