The discovery of new superconductors through traditional trial-and-error experimental methods is both challenging and costly. A data-driven strategy can speed up the time-consuming exploration process...
Critical lateral dimension of nanopedestals for ultimate relief of strain from lattice mismatch in Ge on Si
Nanopedestals (NPs) that can ultimately relieve the strain in the lattice-mismatched heterostructures grown on them are investigated. The strain relief is achieved by the local compliance associated w...
Magnus force induced magnetic diode effect in skyrmion systems
We show that skyrmions can exhibit a “magnetic diode effect,” where there is a nonreciprocal response in the transport when the magnetic field is reversed. This effect can be achieved for skyrmions mo...

We have investigated the electric field (E-field) induced modulation of perpendicular magnetic anisotropy (PMA) in both amorphous and crystalline W/CoFeB/MgO/HfO2 ultra-thin films. We find that in the...
Chirality reversal of exceptional points in a dual-channel graphene-tunable terahertz metasurface
In non-Hermitian systems, a special degeneracy known as an exceptional point (EP) arises from the coalescence of both eigenvalues and eigenvectors of the Hamiltonian. Chiral EPs, which exhibit polariz...
