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 ...
Active disturbance rejection control applied to a twin-rotor system
(Universidade Federal de Minas GeraisUFMG, 2017-04-07)
The problem of controlling the nonlinear system known as the Twin-Rotor System (TRS) using the Active Disturbance Rejection Control (ADRC) technique is investigated in this work. The TRS is a commercial didactical experiment ...
Generalized invariants and quantum evolution of open fermionic systems
(2000)
Open systems acquire time-dependent coupling constants through interaction with an external field or environment. We generalize the Lewis–Riesenfeld invariant theorem to open system of quantum fields after second quantization. ...
Non-commutative differential calculus of some algebras of polynomial type having PBW bases
(Bogotá - Ciencias - Maestría en Ciencias - MatemáticasDepartamento de MatemáticasUniversidad Nacional de Colombia - Sede Bogotá, 2020-06-12)
In this work, we study the notion of differential calculus associated to an associative algebra, from its origin in manifolds geometry, to some generalizations in non commutative differential geometry. In particular, we ...
