Abstract

Quasiparticles play a crucial role in describing the properties of many-particle systems in condensed matter physics. As quasiparticles move through a crystal, they experience frequent elastic and inelastic scatterings due to many-particle interactions, resulting in a finite lifetime within a certain energy range [1-4]. At zero temperature, electron-electron (e-e) Coulomb scatterings are the primary source of many-particle interactions. The quasiparticle concept differs from that of real particles in that it only demonstrates a one-to-one correspondence between state energy and wavevector in the dispersion relation [5]. The properties of quasiparticles are determined by their self-energies, which have real and imaginary components that are precisely defined by the self-consistent Dyson equation [6]….
