Determination of the gluon condensate and the four quark condensate via FESR
(1988)
The dimension four gluon condensate and the dimension six four-quark condensate are estimated with the help of FESR by analyzing the ?-meson channel. We find that the first is a factor 2 5 and the second is (in absolute ...
Is there a flaw in the seminal Bohr-Rosenfeld paper on the measurement problem of the free quantum electromagnetic field?
(Facultad de IngenieríaIngeniería TelemáticaDepartamento Académico de Tecnologías de Información y Comunicaciones (TICs)Santiago de Cali, 2000-03-01)
In 1933, Bohr and Rosenfeld published a seminal paper in which they claimed to solve the measurement problem of the free quantum electromagnetic field. In 1951, however, Corinaldesi discovered, in the analysis of the ...

Esta dissertação tem como foco revisar alguns dos mais importantes avanços no estudo de Teorias de Campo Supersimétricas que ocorreram desde 1994. Mais especificamente, o foco será dado a teorias d = 4, N = 2 super Yang-Mills ...
Toda lattice field theories, discrete W algebras, Toda lattice hierarchies and quantum groups
(1996-10-31)
In analogy with the Liouville case we study the sl3 Toda theory on the lattice and define the relevant quadratic algebra and out of it we recover the discrete W3 algebra. We define an integrable system with respect to the ...

Entanglement of excited states in critical spin chains
(IOP PUBLISHING LTDBRISTOL, 2012)
Renyi and von Neumann entropies quantifying the amount of entanglement in ground states of critical spin chains are known to satisfy a universal law which is given by the conformal field theory (CFT) describing their scaling ...
On the generalized eigenvalue method for energies and matrix elements in lattice field theory
(INT SCHOOL ADVANCED STUDIES, 2009)
We discuss the generalized eigenvalue problem for computing energies and matrix elements in lattice gauge theory, including effective theories such as HQET. It is analyzed how the extracted effective energies and matrix ...
