Real Space Visualization of Order-Disorder Transition in BaTiO3
Yang Zhang, Xiaoming Shi, Suk Hyun Sung +4
Ferroelectricity in BaTiO3 was observed nearly eighty years ago, but the mechanism underlying its ferroelectric-paraelectric phase transition remains elusive. The order-disorder tr…

Unconventional polaronic ground state in superconducting LiTiO
Zubia Hasan, Grace A. Pan, Harrison LaBollita +23
Geometrically frustrated lattices can display a range of correlated phenomena, ranging from spin frustration and charge order to dispersionless flat bands due to quantum interferen…

Inverse Melting of Polar Order in Chemically Substituted BaTiO3
Yang Zhang, Suk Hyun Sung, Colin B. Clement +2
In many condensed matter systems, long range order emerges at low temperatures as thermal fluctuations subside. In the presence of competing interactions or quenched disorder, howe…
