Terahertz stimulated parametric downconversion of a magnon mode in an antiferromagnet
Zhuquan Zhang, Yu-Che Chien, Man Tou Wong +6
In condensed matter systems, interactions between collective modes offer avenues for nonlinear coherent manipulation of coupled excitations and quantum phases. Antiferromagnets, wi…
Emergent Trion Resonance Driven by Lattice Reconstruction in a Moiré Superlattice
Zhida Liu, Haonan Wang, Xiaohui Liu +20
We investigate how many-electron excited states emerge in twisted MoSe2 homobilayers when the lattice reconstructions evolve. Notably, we identify a new trion resonance that arises…
Electrostatic moiré potential from twisted-hBN layers
Dong Seob Kim, Roy C. Dominguez, Rigo Mayorga-Luna +17
Moiré superlattices formed by vertically stacking van der Waals layers host a rich variety of correlated electronic phases and function as novel photonic materials. The moiré poten…
Terahertz field-induced nonlinear coupling of two magnon modes in an antiferromagnet
Zhuquan Zhang, Frank Y. Gao, Jonathan B. Curtis +9
Magnons are quantized collective spin-wave excitations in magnetically ordered materials. Revealing their interactions among these collective modes is crucial for the understanding…
Terahertz field-driven magnon upconversion in an antiferromagnet
Zhuquan Zhang, Frank Y. Gao, Yu-Che Chien +10
Tailored light excitation and nonlinear control of lattice vibrations have emerged as powerful strategies to manipulate the properties of quantum materials out of equilibrium. Gene…
Terahertz Field-Induced Reemergence of Quenched Photoluminescence in Quantum Dots
Jiaojian Shi, Frank Y. Gao, Zhuquan Zhang +13
Continuous and concerted development of colloidal quantum-dot light-emitting diodes over the past two decades has established them as a bedrock technology for the next generation o…
Snapshots of a light-induced metastable hidden phase driven by the collapse of charge order
Frank Y. Gao, Zhuquan Zhang, Zhiyuan Sun +6
Nonequilibrium hidden states, both transient and long-lived, provide a unique window into thermally inaccessible regimes of strong coupling between microscopic degrees of freedom i…
All-optical fluorescence blinking control in quantum dots with ultrafast mid-infrared pulses
Jiaojian Shi, Weiwei Sun, Hendrik Utzat +7
Photoluminescence (PL) intermittency is a ubiquitous phenomenon detrimentally reducing the temporal emission intensity stability of single colloidal quantum dots (CQDs) and the emi…
