Observation of room-temperature ferroelectricity in elemental Te nanowires
Jinlei Zhang, Jiayong Zhang, Yaping Qi +10
Ferroelectrics are essential in low-dimensional memory devices for multi-bit storage and high-density integration. A polar structure is a necessary premise for ferroelectricity, ma…
Constructive Quantum Interference in a Photo-Chemical Reaction of Rb Bose Einstein Condensate
Sumit Suresh Kale, Yong P. Chen, Sabre Kais
Interferences emerge when multiple pathways coexist together leading towards the same result. A Recent study by Blasing and coworkers [PRL 121(7):073202] showed that in a photo-ass…
Opposite current-induced spin polarizations in bulk-metallic Bi2Se3 and bulk-insulating Bi2Te2Se topological insulator thin flakes
Jifa Tian, Cüneyt Şahin, Ireneusz Miotkowski +2
One of the most fundamental and exotic properties of 3D topological insulators (TIs) is spin-momentum-locking (SML) of their topological surface states (TSSs), promising for potent…
Spin-momentum entanglement in a Bose-Einstein condensate
Sumit Suresh Kale, Yijue Ding, Yong P. Chen +2
Entanglement is at the core of quantum information processing and may prove essential for quantum speed-up. Inspired by both theoretical and experimental studies of spin-momentum c…
Gate field effects on the topological insulator BiSbTeSe2 interface
Shuanglong Liu, Yang Xu, Yun-Peng Wang +3
Interfaces between two topological insulators are of fundamental interest in condensed matter physics. Inspired by experimental efforts, we study interfacial processes between two…
Tuning insulator-semimetal transitions in 3D topological insulator thin films by inter-surface hybridization and in-plane magnetic fields
Yang Xu, Guodong Jiang, Ireneusz Miotkowski +2
A pair of Dirac points (analogous to a vortex-antivortex pair) associated with opposite topological numbers (with Berry phases) can be merged together through parameter tuni…
