Particle-hole asymmetry and quantum confinement effects on the magneto-optical response of topological insulator thin-films
Mahmoud M. Asmar, Gaurav Gupta, Wang-Kong Tse
Intrinsically broken symmetries in the bulk of topological insulators (TIs) are manifested in their surface states. In spite of particle-hole asymmetry in TIs, it has often been as…
Large Landau level splitting with tunable one-dimensional graphene superlattice probed by magneto capacitance measurements
Manabendra Kuiri, Gaurav Kumar Gupta, Yuval Ronen +2
The unique zero energy Landau Level of graphene has a particle-hole symmetry in the bulk, which is lifted at the boundary leading to a splitting into two chiral edge modes. It has…
Ultrafast and low-energy switching in voltage-controlled elliptical pMTJ
Jiefang Deng, Gengchiau Liang, Gaurav Gupta
Switching magnetization in a perpendicular magnetic tunnel junction (pMTJ) via voltage controlled magnetic anisotropy (VCMA) has shown the potential to markedly reduce the switchin…
Quantum spin Hall density wave insulator of correlated fermions
Gaurav Kumar Gupta, Tanmoy Das
We present the theory of a new type of topological quantum order which is driven by the spin-orbit density wave order parameter, and distinguished by topological invariant. W…
Switching based Spin Transfer Torque Oscillator with zero-bias field and large tuning-ratio
Gaurav Gupta, Zhifeng Zhu, Gengchiau Liang
We propose a novel concept of obtaining oscillations with frequencies in very-high frequency (VHF) and ultra-high frequency (UHF) bands. A traditional spin torque nano-oscillator (…
