Galilean-Covariant clifford algebras in the phase-space representation
(Springer Verlag, 2005)
We apply the Galilean covariant formulation of quantum dynamics to derive
the phase-space representation of the Pauli–Schr¨odinger equation for the density
matrix of spin-1/2 particles in the presence of an electromagnetic ...
Thermal Lie Groups, Classical Mechanics, and Thermofield Dynamics
(Annals of Physics, 1996)
The concept of thermoalgebra, a kind of representation for the Lie-symmetries developed in connection with thermal quantum field theory, is extended to study unitary representations of the Galilei group for thermal classical ...
Quantum generalized Vlasov equation
(1995)
An electronic system is considered as a quantum plasma characterized by a plasma parameter γ0 ⪡ 1, over short times. Using the Dynamics of Correlations (a many-body theory based on the Liouville-von Neumann equation in the ...
A note on the quasi-stationary distribution of the shiryaev martingale on the positive half-line
(Society for Industrial and Applied Mathematics Publications, 2019)
We obtain a closed-form formula for the quasi-stationary distribution of the classical Shiryaev martingale diffusion considered on the positive half-line [A, +∞) withA>0 fixed; the state space’s left endpoint is assumed ...
Asymptotic Stability of High-dimensional Zakharov-Kuznetsov Solitons
(2016)
We prove that solitons (or solitary waves) of the Zakharov-Kuznetsov (ZK) equation, a physically relevant high dimensional generalization of the Kortewegde Vries (KdV) equation appearing in Plasma Physics, and having mixed ...
Dinâmica de coerência e decoerência de estados em redes de osciladores quânticos dissipativos.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2004-07-02)
In this thesis we studied the coherence and decoherence dynamics of states in
a network of dissipative quantum oscillators. The coherence dynamics refers to
the swap and recurrence process of states between the oscillators ...
Difusão caótica em bilhares dependentes do tempo
(Universidade Estadual Paulista (Unesp), 2021-12-17)
Neste trabalho estudamos as propriedades dinâmicas de um bilhar clássico com fronteira dependente do tempo. A conjectura Loskutov-Ryabov-Akhinshin (LRA) diz que se um bilhar exibe componentes caóticas em sua dinâmica com ...
