Optically Induced Picosecond Lattice Compression in the Dielectric Component of a Strongly Coupled Ferroelectric/Dielectric Superlattice
Deepankar Sri Gyan, Hyeon Jun Lee, Youngjun Ahn +13
Above-bandgap femtosecond optical excitation of a ferroelectric/dielectric BaTiO3/CaTiO3 superlattice leads to structural responses that are a consequence of the screening of the s…
Orbital-selective time-domain signature of nematicity dynamics in the charge-density-wave phase of LaEuSrCuO
Martin Bluschke, Naman K. Gupta, Hoyoung Jang +23
Understanding the interplay between charge, nematic, and structural ordering tendencies in cuprate superconductors is critical to unraveling their complex phase diagram. Using pump…
Weak-coupling to strong-coupling quantum criticality crossover in a Kitaev quantum spin liquid -RuCl
Jae-Ho Han, Seung-Hwan Do, Kwang-Yong Choi +5
We report an unprecedented quantum criticality crossover representing two different universal scaling behaviors in a Kitaev quantum magnetic material -RuCl. -RuCl pre…
Characterization of photoinduced normal state through charge density wave in superconducting YBaCuO
H. Jang, S. Song, T. Kihara +17
The normal state of high-Tc cuprates has been considered one of the essential topics in high-temperature superconductivity research. However, compared to the high magnetic fields s…
