Site Preferences and "Coloring Problem" in Cu-doped BiMnO Quadruple Perovskite
Cheng Peng, Mingyu Xu, Yang Zhang +3
Lightly Cu-doped BiMnO (x = 0.05, 0.10, and 0.15) was investigated using high-pressure synthesis, single-crystal X-ray diffraction, pair distribution function (PDF) anal…
Nanoscale Polar Landscapes in Quantum Paraelectric SrTiO3
Yang Zhang, Suk Hyun Sung, Nishkarsh Agarwal +5
SrTiO3 is a textbook quantum paraelectric, with ferroelectricity purportedly suppressed by quantum fluctuations of ionic positions down to the lowest temperatures. The precise real…
Melting of Charge Density Waves in Low Dimensions
Jeremy M. Shen, Alex Stangel, Suk Hyun Sung +9
Charge density waves (CDWs) are collective electronic states that can reshape and melt, even while confined within a rigid atomic crystal. In two dimensions, melting is predicted t…
Liquid Helium Cryogenic TEM below 1 Ã
Suk Hyun Sung, Maya Gates, Nishkarsh Agarwal +10
Next-generation cryogenic transmission electron microscopes (TEM) aim to achieve high-resolution imaging at ultracold sample temperatures (< 90 K) and over extended hold times. Low…
Evidence of competing ground states between fractional Chern insulator and antiferromagnetism in moiré MoTe2
Xumin Chang, Feng Liu, Fan Xu +18
Two-dimensional moire materials present unprecedented opportunities to explore quantum phases of matter arising from the interplay of band topology and strong correlations.One of t…
