ON THE QUADRATIC FOCK FUNCTOR
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2012)
We prove that the quadratic second quantization of an operator p on L-2(R-d) boolean AND L-infinity(R-d) is an orthogonal projection on the quadratic Fock space if and only if p is a multiplication operator by a characteristic ...
Fock space for fermion-like lattices and the linear Glauber model
(ELSEVIER SCIENCE BV, 2008)
The concept of Fock space representation is developed to deal with stochastic spin lattices written in terms of fermion operators. A density operator is introduced in order to follow in parallel the developments of the ...

Superintegrability of the Fock–Darwin system
(2017-08-01)
The Fock–Darwin system is analyzed from the point of view of its symmetry properties in the quantum and classical frameworks. The quantum Fock–Darwin system is known to have two sets of ladder operators, a fact which ...
Slicing the Fock space for state production and protection
(American Physical Society - APSCollege Park, 2014-09)
In this paper we present a protocol to engineer interactions confined to subspaces of the Fock space in trapped ions: we show how to engineer upper-bounded, lower-bounded, and sliced Jaynes-Cummings (JC) and anti-Jaynes-Cummings ...
O operador espalhamento para férmions num campo externo em Thermofield Dynamics
(Universidade Estadual Paulista (Unesp), 2002-08)
O método de segunda quantificação é utilizado para construir o operador espalhamento S no espaço de Fock, no contexto de Thermofield Dynamics (TFD), para o campo de Dirac sujeito a um potencial eletromagnético externo ...
