Fock representation
In quantum mechanics, a Fock state or number state is a quantum state that is an element of a Fock space with a well-defined number of particles (or quanta). These states are named after the Soviet physicist Vladimir Fock. Fock states play an important role in the second quantization formulation of quantum mechanics. The particle representation was first treated in detail by Paul Dirac for bosons and by Pascual Jord… WebMar 23, 2024 · Many of them are Fock representations, corresponding to fields of the same spin (and charge eventually) but with different masses. There are, however, also …

Webthe second-quantized representation for many-body post Hatree-Fock (HF) theories. In the LCAO-MO represen-tation, each molecular orbital is represented as a linear combination of a set of atomic orbitals. The expansion coefficients of the MOs in terms of the AOs are obtained by solving the pseudo-eigenvalue Fock equation using the SCF procedure. WebJan 29, 2024 · Representations of various states of a harmonic oscillator on the phase plane. The bold black point represents a classical state with the complex amplitude α, with the dashed line showing its trajectory. The (very imperfect) classical images of the Fock states with n = 0, 1 , and 2 are shown in blue.
WebFrom statistical mechanics arguments in the Fock basis, the mean photon number of a mode with wavevector k and polarization state s for a black body at temperature T is known to be The P representation of the black body is In other words, every mode of the black body is normally distributed in the basis of coherent states. WebWick algebras and the Fock representation and show that, in the braided case, the kernel of the Fock representation is generated by the kernel of the Fock inner product. In sec. 3 we prove that if the operator T is braided and kTk ≤ 1, then the kernel of the Fock inner product coincides with the two-sided ideal generated by ker(1+T).
