Spin-dependent three-nucleon force effects on nucleon-deuteron scattering
We construct a phenomenological three-nucleon force (3NF) model that gives a
good description of polarization observables in elastic nucleon-deuteron
(N-) scattering at a low energy together with a realistic nucleon-nucleon
force and a 3NF arising from the exchange of two pions. Parameters of the
model, which consists of spin-independent, spin-orbit, and tensor components,
are determined to reproduce the three-nucleon binding energy and polarization
observables in N-d scattering at 3 MeV. Predictions of the model 3NF on N-d
polarization observables at higher energies are examined, and effects of each
component on the observables are investigated.Comment: 12 pages, 6 figures, submitted to Phys. Rev.
Pressure, Resistance, and Current Activation of Anisotropic Compressible Hall States
Thermodynamic and electric properties of anisotropic compressible Hall states
at higher Landau levels are studied using a mean field theory on the von
Neumann lattice basis. It is shown that resistances agree with the recent
experiments of anisotropic compressible states and the states have negative
pressure. As implications, the collapse phenomena of the integer quantum Hall
effect are discussed.Comment: 4 pages, 5 figures, to be published in Physica
A final solution to the mind-body problem by quantum language
Recently we proposed “quantum language”, which was not only characterized
as the metaphysical and linguistic turn of quantum mechanics but also the
linguistic turn of Descartes = Kant epistemology. And further we believe that
quantum language is the only scientifically successful theory in dualistic idealism.
If this turn is regarded as progress in the history of western philosophy
(i.e., if “philosophical progress” is defined by “approaching to quantum language”),
we should study the linguistic mind-body problem more than the
epistemological mind-body problem. In this paper, we show that to solve the
mind-body problem and to propose “measurement axiom” in quantum language
are equivalent. Since our approach is always within dualistic idealism,
we believe that our linguistic answer is the only true solution to the mindbody
problem
