We resolve the controversy regarding the stability of the monopole condensation in the one-loop effective action of SU(2) QCD by calculating the imaginary part of the effective action with two different methods at one-loop order. Our result confirms that the effective action for the magnetic background has no imaginary part but the one for the electric background has a negative imaginary part. ...

Thought experiment is one of the most widely-used and least understood techniques in philosophy. A thought experiment is a process of reasoning carried out within the context of a well-articulated imaginary scenario in order to answer a specific question about a non-imaginary situation. The aim of my dissertation is to show that both the powers and the limits of this methodology can be traced t...

abstract: focusing on spiritual and mental needs of slow-pace people i.e. mentally retarded people has been always an integral part of designing spaces for them. according to lacan’s way of thinking, real, imaginary and symbolic orders are three ways of expression through human’s reality language and it usually considers reality as a combination of symbolic and imaginary orders. this research a...

The application of the optimized expansion for the quantum-mechanical propagation in the anharmonic potential λx4 is discussed for real and imaginary time. The first order results in the imaginary time formalism provide approximations to the free energy and particle density which agree well with the exact results in the whole range of temperatures.
