Isotopically enriched epitaxial CaWO thin films for Er spin-photon quantum interfaces
Hanlin Tang, Kidae Shin, Ashwin K. Boddeti +10
Rare earth ion (REI)-doped oxide thin films are attractive for the application of quantum interconnects due to their stable optical levels and scalability. Among them, Er$^…
Layer controlled orbital selective Mott transition in monolayer nickelate
Byungmin Sohn, Minjae Kim, Sangjae Lee +14
Dimensionality and electronic correlations are crucial elements of many quantum material properties. An example is the change of the electronic structure accompanied by the loss of…
Coexisting Kagome and Heavy Fermion Flat Bands in YbCrGe
Hanoh Lee, Churlhi Lyi, Taehee Lee +16
Flat bands, emergent in strongly correlated electron systems, stand at the frontier of condensed matter physics, providing fertile ground for unconventional quantum phases. Recent…
Re-entrant unconventional superconductivity induced by rare-earth substitution in Nd1-xEuxNiO2 thin films
Dung Vu, Hangoo Lee, Daniele Nicoletti +17
High temperature superconductivity is typically associated with strong coupling and a large superconducting gap, yet these characteristics have not been demonstrated in the nickela…
Lifetime-limited Gigahertz-frequency Mechanical Oscillators with Millisecond Coherence Times
Yizhi Luo, Hilel Hagai Diamandi, Hanshi Li +9
High-frequency mechanical oscillators with long coherence times are essential to realizing a variety of high-fidelity quantum sensors, transducers, and memories. However, the unpre…
THz carrier dynamics in interface two-dimensional electron gases
Ahana Bhattacharya, Andri Darmawan, Jeong Woo Han +10
A two-dimensional electron gas (2DEG) forms at the interface of complex oxides like (STO) and (LTO), despite each material having a low native conductivity,…
