Cooperative photoinduced metastable phase control in strained manganite films
Jingdi Zhang, Xuelian Tan, Mengkun Liu +7
A major challenge in condensed matter physics is active control of quantum phases. Dynamic control with pulsed electromagnetic fields can overcome energetic barriers enabling acces…
Ultrafast terahertz spectroscopy study of Kondo insulating thin film SmB: evidence for an emergent surface state
Jingdi Zhang, Jie Yong, Ichiro Takeuchi +2
We utilize terahertz time domain spectroscopy to investigate thin films of the heavy fermion compound SmB6, a prototype Kondo insulator. Temperature dependent terahertz (THz) condu…
Terahertz radiation-induced sub-cycle field electron emission across a split-gap dipole antenna
Jingdi Zhang, Xiaoguang Zhao, Kebin Fan +5
We use intense terahertz pulses to excite the resonant mode (0.6 THz) of a micro-fabricated dipole antenna with a vacuum gap. The dipole antenna structure enhances the peak amplitu…
Nonlinear terahertz devices utilizing semiconducting plasmonic metamaterials
Huseyin R. Seren, Jingdi Zhang, George R. Keiser +6
The development of responsive metamaterials has enabled the realization of compact tunable photonic devices capable of manipulating the amplitude, polarization, wave vector, and fr…
Phase transition in bulk single crystals and thin films of VO2 by nano-infrared spectroscopy and imaging
Mengkun Liu, Aaron J. Sternbach, Martin Wagner +21
We have systematically studied a variety of vanadium dioxide (VO2) crystalline forms, including bulk single crystals and oriented thin films, using infrared (IR) near-field spectro…
