Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Every generation grows up with starships that jump across galaxies in a heartbeat, but the real universe is far less ...

The model of relativistic particle with rigidity whose action A=−α∫ kds depends on the curvature of particle world trajectory k, is studied. The classical motion of the particle is shown to go along a ...

We consider the creation of massless scalar particles by a moving mirror in two-dimensional space-time. The correct form for the Bogoliubov coefficients is given and their high-frequency behavior is ...

Structural batteries are a "massless" alternative to traditional batteries because they are designed to produce and store energy while also serving as a load-bearing part of a vehicle's structure. A ...
