We apply the principle of energy conservation to the motion of the test particle in gravitational field by requiring that its energy, gained by gravitation, has to be balanced by decrease of its rest mass. Due to the change of mass in gravitational field Newton's force law between gravitating bodies is modified, too. With this modified force law we build up the the classical field theory of gra...

Observations in quantum mechanics are subject to complex restrictions arising from the principle of energy conservation. Determining such restrictions, however, has been so far an elusive task, and only partial results are known. In this Letter, we discuss how constraints on the energy spectrum of a measurement device translate into limitations on the measurements which we can effect on a targe...

The different methods of reducing decoherence in quantum devices are discussed from the unified point of view based on the energy conservation principle and the concept of forbidden transitions. Minimal decoherence model, " bang-bang " techniques, Zeno effect and decoherence-free subspaces are studied as particular examples.

OF THESIS 2. Several scholars have investigated contributions that medical theorists made during the 19 th cent:ury to the discovery of the conservation of energy. This thesis investigates such contributions, particularly in Britain and Germany, in greater dc::tDil than has been done hitherto. Beginning with ideas on POW8L of 17th and 18th century British philosophers, the development of an int...

We consider a new approach for gravity theory coupled to Chaplygin matter in which the relativistic formulation of the latter is of crucial importance. We obtain a novel form of matter with dust like density (∼ (volume) −1) and negative pressure. We explicitly show that our results are compatible with a relativistic generalization of the energy conservation principle, derived here.

The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation laws, and get a scale relation relating the energy-momentum and spin tensors. Such scale relation is an intrinsic property for matter fields in Lyra background.
