Random Lie-point symmetries

A double copy for asymptotic symmetries in the self-dual sector
(2021)
We give a double copy construction for the symmetries of the self-dual sectors of Yang-Mills (YM) and gravity, in the light-cone formulation. We find an infinite set of double copy constructible symmetries. We focus on two ...
Asymptotic symmetries and dynamics of three-dimensional flat supergravity
(Springer Verlag, 2014-08)
A consistent set of asymptotic conditions for the simplest supergravity theory
without cosmological constant in three dimensions is proposed. The canonical generators
associated to the asymptotic symmetries are shown to ...
On the real matrix representation of pt-symmetric operators
(Czech Technical University, 2014-05)
We discuss the construction of real matrix representations of PT-symmetric operators. We show the limitation of a general recipe presented some time ago for non-Hermitian Hamiltonians with antiunitary symmetry and propose ...
A física de partículas elementares e o Prêmio Nobel de física 2008
(2008-10-01)
The 2008 Nobel prize of physics pay tribute to three theoretical physicist by their work related to some symmetries of Nature. We briefly comments the importance of these works and the context in which they were done. ...
