Occupation Dynamics of Floquet-Volkov States and Spectral Sum Rule
Xuanxi Cai, Changhua Bao, Benshu Fan +9
Time-periodic light fields can dress electronic states in quantum materials, forming Floquet states whose dynamic occupation determines transient material properties. Here by using…
Light-induced ultrafast glide-mirror symmetry breaking in black phosphorus
Changhua Bao, Fei Wang, Haoyuan Zhong +6
Symmetry breaking plays an important role in fields of physics, ranging from particle physics to condensed matter physics. In solid-state materials, phase transitions are deeply li…
Observation of dichotomic field-tunable electronic structure in twisted monolayer-bilayer graphene
Hongyun Zhang, Qian Li, Youngju Park +18
Twisted bilayer graphene (tBLG) provides a fascinating platform for engineering flat bands and inducing correlated phenomena. By designing the stacking architecture of graphene lay…
Floquet engineering of black phosphorus upon below-gap pumping
Shaohua Zhou, Changhua Bao, Benshu Fan +6
Time-periodic light field can dress the electronic states and lead to light-induced emergent properties in quantum materials. While below-gap pumping is regarded favorable for Floq…
Pseudospin-selective Floquet band engineering in black phosphorus
Shaohua Zhou, Changhua Bao, Benshu Fan +10
Time-periodic light field has emerged as a control knob for manipulating quantum states in solid-state materials, cold atoms and photonic systems via hybridization with photon-dres…
Population inversion and Dirac fermion cooling in 3D Dirac semimetal CdAs
Changhua Bao, Qian Li, Sheng Xu +8
Revealing the ultrafast dynamics of three-dimensional (3D) Dirac fermions upon photoexcitation is critical for both fundamental science and device applications. So far, how the coo…
