Abstract
In the field of modern condensed matter physics, the behavior of quasiparticles has been a major area of research with the advancement of technology and many-body theory. Optical spectroscopy, using ultrafast laser pulses, has become a popular tool for generating and detecting dynamic oscillations of electric charges [1-13]. In 2001, femtosecond spectroscopy demonstrated that dynamic screening takes a finite time (around 10 fs) to establish in GaAs, causing the collective behavior of electrons [13]. Furthermore, a new microscopy technique integrating ultrashort laser pulses and scanning tunneling microscopy (STM) has enabled real-space imaging of transient carrier dynamics in nanostructures [11]. Recently, coherent spectroscopy with nanometer spatial and femtosecond temporal resolution has observed ultrafast coherent dynamics and related nanoscale phenomena [11, 14-16]. As near-field optical microscopes achieve nanoscale imaging, there has been increased interest in plasmon propagation in real space and time [14-16]. The confinement and enhancement of plasma waves in large optical fields can be used to design active plasmonic devices [17-29]….
