Competing Lattice and Defect Dynamics Govern Terahertz-Induced Ferroelectricity in Quantum Paraelectric SrTiO
L. Cheng, K. Hu, S. Yang +3
Intense terahertz (THz) pulses induce transient inversion-symmetry breaking in quantum paraelectric SrTiO, yet the underlying mechanism remains controversial. Using fields up t…

Interplay of spin-orbit coupling and trigonal crystal field enhances superconductivity in (111)
Long Cheng, Jia Liu, Tongying Liu +10
In conventional superconductors, bulk physical properties typically degrade as the film thickness approaches the two-dimensional (2D) limit. Here in the (111) oriented LaAlO3/KTaO3…
