Time-resolved Photoluminescence in Terahertz-driven Hybrid Systems of Plasmons and Excitons
Chen-Yen Lai, D. A. Yarotski, Jian-Xin Zhu
Ultrafast pump-probe technique is a powerful tool to understand and manipulate properties of materials for designing novel quantum devices. An intense, single cycle terahertz pulse…
Absence of diffusion and fractal geometry in the Holstein model at high temperature
Chen-Yen Lai, S. A. Trugman
We investigate the dynamics of an electron coupled to dispersionless optical phonons in the Holstein model, at high temperatures. The dynamics is conventionally believed to be diff…
Optical absorption spectroscopy in hybrid systems of plasmons and excitons
Chen-Yen Lai, S. A. Trugman, Jian-Xin Zhu
Understanding the physics of light emitter in quantum nanostructure regarding scalability, geometry, structure of the system and coupling between different degrees of freedom is im…
Ultrafast X-ray Absorption Spectroscopy of Strongly Correlated Systems: Core Hole Effect
Chen-Yen Lai, Jian-Xin Zhu
In recent years, ultrafast pump-probe spectroscopy has provided insightful information about nonequilibrium dynamics of excitations in materials. In a typical experiment of time-re…
Many-body multi-valuedness of particle-current variance in closed and open cold-atom systems
Mekena Metcalf, Chen-Yen Lai, Massimiliano Di Ventra +1
The quantum variance of an observable is a fundamental quantity in quantum mechanics, and the variance provides additional information other than the average itself. By examining t…
Tunable current circulation in triangular quantum-dot metastructures
Chen-Yen Lai, Massimiliano Di Ventra, Michael Scheibner +1
Advances in fabrication and control of quantum dots allow the realization of metastructures that may exhibit novel electrical transport phenomena. Here, we investigate the electric…
