Entropy Currents for Reversible Processes in a System of Differential equations. -- The Case of Latticized Classical Field Theory --
Holger B. Nielsen, Masao Ninomiya
We consider a very complicated system of some latticized differential equations that is considered as equations of motion for a field theory. We define macro state restrictions for…
Future Dependent Initial Conditions from Imaginary Part in Lagrangian
Holger B. Nielsen, Masao Ninomiya
We want to unify usual equation of motion laws of nature with "laws" about initial conditions, second law of thermodynamics, cosmology. By introducing an imaginary part -- of a sim…
Dirac Sea and Hole Theory for Bosons II -- Renormalization Approach --
Yoshinobu Habara, Yukinori Nagatani, Holger B. Nielsen +1
In bosonic formulation of the negative energy sea, so called Dirac sea presented in the preceding paper [arXiv:hep-th/0603242], one of the crucial points is how to construct a posi…
Dirac Sea and Hole Theory for Bosons I -- A new formulation of quantum field theories --
Yoshinobu Habara, Yukinori Nagatani, Holger B. Nielsen +1
Bosonic formulation of the negative energy sea, so called Dirac sea, is proposed by constructing a hole theory for bosons as a new formulation of the second quantization of bosonic…
Law Behind Second Law of Thermodynamics --Unification with Cosmology--
Holger B. Nielsen, Masao Ninomiya
In an abstract setting of a general classical mechanical system as a model for the universe we set up a general formalism for a law behind the second law of thermodynamics, i.e. re…
Non-existence of Irreversible Processes in Compact Space Time
Holger B. Nielsen, Masao Ninomiya
It is shown that if physical space time were truly compact there would only be of the order of one solutions to the classical field equations with a weighting to be explained. But…
