Combinatorics and Boson normal ordering: A gentle introduction
... Hilbert space constitutes the arena where quantum phenomena can be described. One common realization is Fock space, which is generated by the set of orthonormal vectors |ni representing states with a specified numbers of particles or objects. A particular role in this description is played by the cr ...

2 Quantum Theory of Spin Waves
... would again leave the wave function ψS unchanged, but ψS would not have to vanish. Consequently, symmetric wave functions do allow multiple particles to be in the same state. Particles that do not obey the Pauli exclusion principle obey Bose–Einstein statistics, and are called bosons. We will return ...

The quantum world is not built up from correlations - Philsci
... W . Of course Q̂ and R̂ must commute in order for the joint probability distribution to be well defined, but this is ensured since both operators are defined for different subsystems (with each their own Hilbert space) and are therefore commuting. Secondly, we choose the set of hidden variables to b ...

Quantum Effects Through a Fractal Theory of Motion
... one considers the space-time where particles move changes from classical to nondifferentiable. According to Nottale [11], the transition from classical (differentiable) mechanics to the scale relativistic framework is implemented by passing to a fluid-like description (the fractality of space), cons ...

Compaction of granular materials composed of deformable particles
... 3 Diametral compression of one particle In this section, we study the accuracy and efficiency of the proposed models by considering the behavior of a single particle by using the MPM and BPM approaches. To do so, we compressed a soft particle of radius R = 5 mm between two rigid walls by fixing the bot ...

Ph. D. thesis Quantum Phase Transitions in Correlated Systems
... In this thesis we shall investigate the properties of systems with strong correlations. Correlations are present even in ideal gases: at low temperatures, quantum statistics manifest in entirely different behavior of bosons and fermions. The situation gets more interesting and also more involved whe ...

Fully Adaptive Propagation of the Quantum–Classical Liouville

However, in the case of realistic multidimensional applications the problem of calculating these derivatives becomes intractable. Alternatively, S ...

Lectures on effective field theory - Research Group in Theoretical
... The basic idea behind effective field theory (EFT) is the observation that the nonanalytic parts of scattering amplitudes are due to intermediate process where physical particles can exist on shell (that is, kinematics are such that internal propagators 1/(p2 − m2 + i) in Feynman diagrams can diver ...
