Quantum signatures of transitions from stable fixed points to limit cycles in optomechanical systems
Qing Xia Meng, Zhi Jiao Deng, Zhigang Zhu +1
Optomechanical systems, due to its inherent nonlinear optomechanical coupling, owns rich nonlinear dynamics of different types of motion. The interesting question is that whether t…
Spin Transfer Torque and Electric Current in Helical Edge States in Quantum Spin Hall Devices
Qinglei Meng, Smitha Vishveshwara, Taylor L. Hughes
We study the dynamics of a quantum spin Hall edge coupled to a magnet with its own dynamics. Using spin transfer torque principles, we analyze the interplay between spin currents i…
Fractional Spin Josephson Effect and Electrically Controlled Magnetization in Quantum Spin Hall Edges
Qinglei Meng, Vasudha Shivamoggi, Taylor L. Hughes +2
We explore a spin Josephson effect in a system of two ferromagnets coupled by a tunnel junction formed of 2D time-reversal invariant topological insulators. In analogy with the mor…
Topological Insulator Magnetic Tunnel Junctions: Quantum Hall Effect and Fractional Charge via Folding
Qinglei Meng, Smitha Vishveshwara, Taylor L. Hughes
We provide a characterization of tunneling between coupled topological insulators in 2D and 3D under the influence of a ferromagnetic layer. We explore conditions for such systems…
Gate controlled Spin-Density Wave and Chiral FFLO Superconducting phases in interacting Quantum Spin Hall edge states
Qinglei Meng, Taylor L. Hughes, Matthew J. Gilbert +1
We explore the phases exhibited by an interacting quantum spin Hall edge state in the presence of finite chemical potential (applied gate voltage) and spin imbalance (applied magne…
