Eugene Wigner and Translational Symmetries
Y. S. Kim
As Einstein's unifies the energy-momentum relation for massive and massless particles, Wigner's little group unifies their internal space-time symmetries. It is pointe…
Lorentz Group in Condensed Matter Physics
Y. S. Kim
It is shown that the Lorentz group plays prominent roles in at least two areas in condensed matter physics, namely in the Bogoliubov transformation and optical filters. It is point…
Lorentz Boosts as Squeeze Transformations and Coherence Problems
D. Han, Y. S. Kim
The quark model and the parton model are known to be two different manifestations of the same covariant entity. However, the interaction amplitudes of partons are incoherent while…
Two Different Squeeze Transformations
D. Han, Y. S. Kim
Lorentz boosts are squeeze transformations. While these transformations are similar to those in squeezed states of light, they are fundamentally different from both physical and ma…
