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…
Giant Rashba splitting in PtTe/PtTe heterostructure
Runfa Feng, Yang Zhang, Jiaheng Li +11
Achieving a large spin splitting is highly desirable for spintronic devices, which often requires breaking of the inversion symmetry. However, many atomically thin films are centro…
Moiré enhanced flat band in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Kai Liu +17
The fractional quantum anomalous Hall effect (FQAHE) is a fascinating emergent quantum state characterized by fractionally charged excitations in the absence of magnetic field,whic…
Floquet-Volkov interference in a semiconductor
Changhua Bao, Haoyuan Zhong, Benshu Fan +9
Intense light-field can dress both Bloch electrons inside crystals and photo-emitted free electrons in the vacuum, dubbed as Floquet and Volkov states respectively. These quantum s…
Unveiling an in-plane Hall effect in rutile RuO films
Meng Wang, Jianbing Zhang, Di Tian +2
The in-plane-magnetic-field-induced Hall effect (IPHE) observed in Weyl semimetals and PT-symmetric antiferromagnets has attracted increasing attention, as it breaks the stereotype…
Manipulating the symmetry of photon-dressed electronic states
Changhua Bao, Michael Schüler, Teng Xiao +11
Strong light-matter interaction provides opportunities for tailoring the physical properties of quantum materials on the ultrafast timescale by forming photon-dressed electronic st…
