... virtually untenable if we accept a functionalist account of consciousness. Moreoever, the story works only if the post-duplication organism not inhabited by the Cartesian Ego is not conscious at all: we cannot accept that it is conscious in the absence of an Ego, or that a second Ego is created for ...

Interaction-based nonlinear quantum metrology with a cold atomic ensemble
... the fact that light is made of quanta, i.e., the photons, whose bouncing on the mirror surface has an intrinsic quantum randomness [Caves, 1980]. The second reason is more generic, and concerns the fact that every system is quantum in its nature. Unfortunately we are not used to such a vision and we ...

Loop Quantum Gravity and Effective Matter Theories
... Quantizing a system with infinite degrees of freedom, is commonly known as second quantization. In particle physics this is normally realized with the use of creation and annihilation operators that allows to build up the quantum field with all its basic harmonic excitations. And permits to connect ...

... The quasi-separability of the charges allows the use of this simple functional model. In general, why can we consider the possibility of describing many-electron atoms based on a hydrogen-like atom model, e.g., electronic distribution? This is possible since the interaction among electrons, in gener ...
