Adiabatic approximation for a uniform DC electric field
Zhuo Bin Siu, Mansoor B. A. Jalil, Seng Ghee Tan
In this work, we show that the disorder-free Kubo formula for the non-equilibrium value of an observable due to a DC electric field, represented by in the Hamiltonian,…
Spin accumulation in disordered topological insulator thin films
Zhuo Bin Siu, Ho Cong Son, Mansoor bin Abdul Jalil +1
Topological insulator (TI) thin films differ from the more commonly studied semi-infinite bulk TIs in that the former possesses both top and bottom surfaces where the surface state…
Quantum Capacitance of a Topological Insulator-Ferromagnet Interface
Zhuo Bin Siu, Debashree Chowdhury, Mansoor B. A. Jalil +1
We study the quantum capacitance in a topological insulator thin film system magnetized in the in-plane direction in the presence of an out-of-plane magnetic field and hexagonal wa…
Effective Hamiltonian for surface states of topological insulator nanotubes
Zhuo Bin Siu, Mansoor B. A. Jalil, Seng Ghee Tan
In this work we derive an effective Hamiltonian for the surface states of a hollow topological insulator (TI) nanotube with finite width walls. Unlike a solid TI cylinder, a TI nan…
Spin accumulation in asymmetric topological insulator thin films in out of plane magnetic fields
Zhuo Bin Siu, Debashree Chowdhury, Banasri Basu +1
In this work we study the spin accumulation due to an in-plane electric field in an asymmetric topological insulator (TI) thin film system with an out of plane magnetic field and a…
Influence of Fermi arc states and double Weyl node on tunneling in a Dirac semimetal
Zhuo Bin Siu, Can Yesilyurt, Mansoor B. A. Jalil +1
Most theoretical studies of tunneling in Dirac and the closely related Weyl semimetals have modeled these materials as single Weyl nodes described by the three-dimensional Dirac eq…
Gauge field in systems with spin orbit interactions and additional discrete degrees of freedom to real spin
Zhuo Bin Siu, Mansoor B. A. Jalil, Seng Ghee Tan
The spin gauge field formalism has been used to explain the emergence of out of plane spin accumulation in two-dimensional spin orbit interaction (SOI) systems in the presence of a…
Curvature induced out of plane spin accumulation
Zhuo Bin Siu, Mansoor B. A. Jalil, Seng Ghee Tan
In this work we show that (real space) curvature in the geometry of curved waveguides with Rashba spin orbit interaction (RSOI) can lead to out of plane spin accumulations. We firs…
Effective Hamiltonian for surface states of \ce{Bi2Te3} nanocylinders with hexagonal warping
Zhuo Bin Siu, Mansoor B. A. Jalil, Seng Ghee Tan
The three-dimensional topological insulator \ce{Bi2Te3} differs from other topological insulators in the \ce{Bi2Se3} family in that the effective Hamiltonian of its surface states…
Dirac semimetal thin films in in-plane magnetic fields
Zhuo Bin Siu, Mansoor B. A. Jalil, Seng Ghee Tan
In this work we study the effects of in-plane magnetic fields on thin films of the Dirac Semimetal (DSM) \ce{Na2Bi} where one of the in-plane directions is perpendicular to the …
