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…
