On the Hamiltonian Description of Fluid Mechanics
We suggest the Hamiltonian approach for fluid mechanics based on the dynamics, formulated in terms of Lagrangian variables. The construction of the canonical variables of the fluid sheds a light on the origin of Clebsh variabes, introduced in the previous century. The develoted formalism permitts to relate the circulation conservation (Tompson theorem) with the invariance of the theory with res...
متن کاملDescription of Isolated Macroscopic Systems inside Quantum Mechanics
For an isolated macrosystem classical state parameters c(t) are introduced inside a quantum mechanical treatment. By a suitable mathematical representation of the actual preparation procedure in the time interval [T, to] a statistical operator is constructed as a solution of the Liouvilleevon Neumann equation. exhibiting at time t the state parameters [(t’), to 5 t’ < t, and preparation paramet...
متن کاملA statistical mechanics description of environmental variability in metabolic networks
Many of the chemical reactions that take place within a living cell are irreversible. Due to evolutionary pressures, the number of allowable reactions within these systems are highly constrained and thus the resulting metabolic networks display considerable asymmetry. In this paper, we explore possible evolutionary factors pertaining to the reduced symmetry observed in these networks, and demon...
متن کاملQuantum Mechanics and Nonlocality: In Search of Instructive Description
A problem with an instructive description of measurement process for sufficiently separated entangled quantum systems is well known. More precise and crafty experiments together with new technological challenges raise questions about sufficiency of formal use of “black-box” Copenhagen paradigm without subtleties of transition between quantum and classical worlds. In this work are discussed appl...
متن کاملOn the description of subsystems in relativistic hypersurface Bohmian mechanics.
A candidate for a realistic relativistic quantum theory is the hypersurface Bohm-Dirac model. Its formulation uses a foliation of space-time into space-like hypersurfaces. In order to apply the theory and to make contact with the usual quantum formalism, one needs a framework for the description of subsystems. The presence of spin together with the foliation renders the subsystem description mo...
