Non-perturbative theory of valley splitting in Si qubits from variational wave function: periodic effects of shear strain and asymptotic freedom in the wiggle-well potential
Johannes L. P. Steinschuld, Hendrik J. Bluhm, Seyed Akbar Jafari
Valley splitting sets the energy scale at which spin and valley degrees of freedom hybridize in silicon quantum-well qubits, but its sensitivity to interface structure makes it dif…
Valley-Enabled Intrinsic Dresselhaus Spin-Orbit Coupling in Silicon
Johannes L. P. Steinschuld, Hendrik J. Bluhm, Lars R. Schreiber +1
We develop a symmetry-based theory of spin-orbit-valley coupling in silicon that reveals an intrinsic source of Dresselhaus spin-orbit coupling independent of interfaces or externa…
Zeeman-like coupling to valley degree of freedom in Si-based spin qubits
S Akbar Jafari, Hendrik J Bluhm, David P Divincenzo
Increasing the valley splitting in Si-based heterostructures is critical for improving the performance of semiconductor qubits. This paper demonstrates that the two low-energy cond…
Two-dimensional M2X2 family with emerging semiconducting, semimetallic, and magnetic properties
Yasin Yekta, Hamidreza Ramezani, Hanif Hadipour +1
The exploration for novel two-dimensional (2D) materials with diverse electronic characteristics has attracted growing interest in recent years. Using density functional theory (DF…
Material and size dependent corrections to conductance quantization in anomalous Hall effect from anomaly inflow
Armin Ghazi, Seyed Akbar Jafari
In quantum anomalous Hall (QAH) systems, the Hall conductance is quantized and the corresponding effective topological theory of the system is the Chern-Simons theory. The conducta…
Localized magnetic states in three dimensional Dirac solids
M. Mashkoori, I. Mahyaeh, S. A. Jafari
Formation of localized magnetic states in a metallic host is a classic problem ofcondensed matter physics formalized by P. W. Anderson within the so called single impurity Anderson…
