If an imaginary quasiparticle has a mass depending on speed

Click For Summary
SUMMARY

The discussion centers on the concept of an imaginary quasiparticle with mass that varies with speed. Participants assert that mass is defined as the energy of a particle at rest, making the idea of velocity-dependent mass nonsensical. The notion of infinite mass at rest is challenged, as it lacks a physical basis. Overall, the conversation emphasizes the importance of adhering to established definitions in physics regarding mass and energy.

PREREQUISITES
  • Understanding of mass-energy equivalence
  • Familiarity with the concept of quasiparticles
  • Basic knowledge of relativistic physics
  • Awareness of the principles of particle physics
NEXT STEPS
  • Research the concept of mass-energy equivalence in detail
  • Study the properties and implications of quasiparticles
  • Explore relativistic effects on mass and energy
  • Investigate the definitions and implications of mass in particle physics
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in advanced concepts of mass and energy in particle physics.

...becoming infinite at rest, doesn't that mean it has infinite mass whatever velocity it has?

How could that quasiparticle be at rest to achieve infinite mass?

What do you mean by "an imaginary quasiparticle becoming infinite at rest"? What source are you getting this from?
 
Mass is defined as the energy a particle has, when it is at rest. Therefore, it makes no sense to speak of a velocity dependent mass.
