My research delves into theoretical and computational studies of condensed matter physics, with an emphasis on THz physics, nonlinear systems, semiconductor heterostructures, acoustoelectronics, and optoelectronic devices. The main objective is to deepen the understanding of optical and transport phenomena in semiconductor nanostructures, leveraging mid-infrared and THz technology.
To achieve this, theoretical models and computational tools are developed using methods such as Nonequilibrium Green’s Functions, the Boltzmann transport equation, and the qualitative theory of differential equations. The work also extends to applied physics, supporting the development of mid-infrared sensors for environmental monitoring with quantum cascade lasers.
