Linearly polarized light enables chiral edge transport in quasi-2D Dirac materials
Mohammad Shafiei, Farhad Fazileh, Milorad V. MiloÅ¡eviÄ
Floquet engineering with high-frequency light offers dynamic control over topological phases in quantum materials. While in 3D Dirac systems circularly polarized light is known to…
Dissipationless transport by design in ultrathin magnetic topological insulator films
Amir Sabzalipour, Mohammad Shafiei, Milorad V. MiloÅ¡eviÄ
Magnetic topological insulators (MTIs) are among the prominent platforms for the next generation of high-speed and low-power spintronic devices. However, unlike their non-magnetic…
Planar Hall effect in ultrathin topological insulator films
Mohammad Shafiei, Milorad V. MiloÅ¡eviÄ
The planar Hall effect (PHE), previously observed in Weyl and Dirac semimetals due to the chiral anomaly, emerges with a different origin in topological insulators (TIs), where in-…
Light-induced dissipationless states in magnetic topological insulators with hexagonal warping
Mohammad Shafiei, Milorad V. MiloÅ¡eviÄ
Magnetic impurities in topological insulators (TIs) induce backscattering via magnetic torque, unlike pristine TIs where spin-orbit locking promotes dissipationless surface states.…
Towards Advanced Chiral Sensors: Enhanced Helicity-Dependent Photocurrent in Ultrathin Topological Insulator Films
Mohammad Shafiei, Sahar Safavi Moayeri, Milorad V. MiloÅ¡eviÄ
Chirality, a fundamental property of asymmetric structures, plays a crucial role in pharmaceutical, biological and chemical systems, offering a powerful tool for screening organic…
