چکیده

Quantum mechanics gives exceedingly accurate predictions for atomic and nuclear systems. Classical mechanics is just as successful for planetary motion. When it is necessary or convenient to describe part of the system classically and another part quantum mechanically both languages are combined. The phenomena that are treated by this mixed dynamics range form the one-loop quantum gravity [1] and quantum cosmology [2] to gas kinetics [3] and dynamics of chemical reactions [4]. Different mixed dynamics schemes are adopted for different situations. Often they produce a good agreement with experimental data or reasonable physical models, but these schemes are also prone to sudden breakdowns and require fine tuning of parameters or a careful selection of allowed initial states.

Motivated by the question what it is that makes quantum mechanics a holistic theory (if so), I try to define for general physical theories what we mean by 'holism'. For this purpose I propose an epistemological criterion to decide whether or not a physical theory is holistic, namely: a physical theory is holistic if and only if it is impossible in principle to infer the global properties, as as...

Abstract. Relativistic heavy ion collisions produce thousands of particles, and it is sometimes difficult to believe that these processes allow for a theoretical description directly in terms of the underlying theory – QCD. However once the parton densities are sufficiently large, an essential simplification occurs – the dynamics becomes semi– classical. As a result, a simple ab initio approach...

It is a fascinating subject to explore how well we can understand the processes of life on the basis of fundamental laws of physics. It is emphasised that viewing biological processes as manipulation of information extracts their important features. This information processing can be analysed using well-known methods of mathematical physics. The lowest level of biological information processing...

It is proved that a quantum computer with fixed and permanent interaction of diagonal type between qubits proposed in the work quant-ph/0201132 is universal. Such computer is controlled only by one-qubit quick transformations, and this makes it feasible.
