Is there any (general accepted) conceptual precise and mathematically
rigorous  definition of the concepts "particle" and "quasiparticle" in
the framework of non-relativistic quantum mechanics?
I am mainly interested in quasiparticles, but I think if there is a

There has been a fair amount of discussion on sci.physics.foundations in
the thread "Might Foldy-Wouthuysen Transformations contain a Hidden
Fermion Mass Generation Mechanism?" regarding the fact that the velocity
operator "alpha" of the Dirac Hamiltonian appears to suggest that a

of the topic, even after a thorough search,
and despite a similar positing some weeks ago
in another group.]

The issue of causal signature has importance for four major
applications:
* the design of more refined empirical tests to determine what the
spacetime signature actually is

In the past, I have usually assumed that the z shift distance
relationship in a linearly accelerating reference frame could be
obtained by naive application of the gravitational Doppler shift thus:
1 + z = 1 / (1 - g.d/c^2)

I'm confused about the following three questinos.
Suppose we have local N=(1,0) supersymmetry in 10-dimensional
minkowski spacetime. In 10-dimensions we have two real irreducible
unique 16-dimensional majorana-weyl representations of Spin(9,1)
