Visualization of Tunable Electronic Structure of Monolayer TaIrTe
Sandy Adhitia Ekahana, Aalok Tiwari, Souvik Sasmal +16
Monolayer TaIrTe is an ideal platform to explore the tunability of band topology where charge doping converts the quantum spin Hall insulator (QSHI) state into a dual QSHI stat…
Cavity based sensing of antiferromagnetic canting and nonzero-momentum spin waves in a van der Waals cavity-magnon-polariton system
Supriya Mandal, Krishnendu Maji, Lucky N. Kapoor +6
Cavity-magnon-polaritons are hybrid excitations from the interaction between cavity photons and magnons, the quanta of collective spin oscillations. Along with the tunability of th…
Direct visualization of gate-tunable flat bands in twisted double bilayer graphene
Souvik Sasmal, Ryan Muzzio, Ahmed Khalifa +12
The symmetry-broken correlated states in twisted double bilayer graphene (TDBG) can be tuned via several external knobs, including twist angle, displacement field, and carrier dens…
Magnetization Dependent In-plane Anomalous Hall Effect in a Low-dimensional System
I-Hsuan Kao, Ravi Kumar Bandapelli, Zhenhong Cui +17
Anomalous Hall Effect (AHE) response in magnetic systems is typically proportional to an out-of-plane magnetization component because of the restriction imposed by system symmetrie…
