Second Harmonic Generation in Topological Insulators under Quantizing Magnetic Fields

Autor: Chang, Kainan, Zubair, Muhammad, Cheng, Jin Luo, Tse, Wang-Kong

We theoretically investigate the second harmonic generation (SHG) of topological insulator surface states in a perpendicular magnetic field. Our theory is based on the microscopic expression of the second-order magneto-optical conductivity developed

Shadow of novel rotating black holes in GR coupled to nonlinear electrodynamics and constraints from EHT results

Autor: Raza, Muhammad Ali, Sarikulov, Furkat, Rayimbaev, Javlon, Zubair, Muhammad, Ahmedov, Bobomurat, Stuchlik, Zdenek

We study the optical properties of spacetime around a novel regular black hole (BH) in general relativity (GR) coupled to nonlinear electrodynamics (NED), which is asymptotically flat. First, we study the angular velocity and Lyapunov exponent in uns

Large Rashba splittings in bulk and monolayer of BiAs

Autor: Zubair, Muhammad, Evangelista, Igor, Khalid, Shoaib, Medasani, Bharat, Janotti, Anderson

Two-dimensional materials with Rashba split bands near the Fermi level are key to developing upcoming next-generation spintronics. They enable generating, detecting, and manipulating spin currents without an external magnetic field. Here, we propose

Reconfigurable Intelligent Surfaces: Interplay of Unit-Cell- and Surface-Level Design and Performance under Quantifiable Benchmarks

Autor: Rafique, Ammar, Hassan, Naveed Ul, Zubair, Muhammad, Naqvi, Ijaz Haider, Mehmood, Muhammad Qasim, Yuen, Chau, Di Renzo, Marco, Debbah, Merouane

The ability of reconfigurable intelligent surfaces (RIS) to produce complex radiation patterns in the far-field is determined by various factors, such as the unit-cell's size, shape, spatial arrangement, tuning mechanism, the communication and contro

Rate dependence of damage formation in metallic-intermetallic Mg-Al-Ca composites

Autor: Medghalchi, Setareh, Zubair, Muhammad, Karimi, Ehsan, Sandlöbes-Haut, Stefanie, Kerzel, Ulrich, Korte-Kerzel, Sandra

We study a cast Mg-4.65Al-2.82Ca alloy with a microstructure containing $\alpha$-Mg matrix reinforced with a C36 Laves phase skeleton. Such ternary alloys are targeted for elevated temperature applications in automotive engines since they possess exc

Inversion Symmetry Breaking in Epitaxial Ultrathin Bi (111) Films

Autor: Inbar, Hadass S., Zubair, Muhammad, Dong, Jason T., Engel, Aaron N, Dempsey, Connor P., Chang, Yu Hao, Nishihaya, Shinichi, Khalid, Shoaib, Fedorov, Alexei V., Janotti, Anderson, Palmstrøm, Chris J.

Bismuth (Bi) films hold potential for spintronic devices and topological one-dimensional edge transport. Large-area high-quality (111) Bi ultrathin films are grown on InSb (111)B substrates. Strong film-substrate interactions epitaxially stabilize th
