Higher lattices, discrete two-dimensional holonomy and topological phases in (3+1) D with higher gauge symmetry
Alex Bullivant, Marcos Calcada, Zoltán Kádár +2
Higher gauge theory is a higher order version of gauge theory that makes possible the definition of 2-dimensional holonomy along surfaces embedded in a manifold where a gauge 2-con…
Topological phases from higher gauge symmetry in 3+1D
Alex Bullivant, Marcos Calçada, Zoltán Kádár +2
We propose an exactly solvable Hamiltonian for topological phases in dimensions utilising ideas from higher lattice gauge theory, where the gauge symmetry is given by a finit…
Distributional approach to point interactions in one-dimensional quantum mechanics
Marcos Calçada, José T. Lunardi, Luiz A. Manzoni +1
We consider the one-dimensional quantum mechanical problem of defining interactions concentrated at a single point in the framework of the theory of distributions. The often ill-de…
On the Salecker-Wigner-Peres clock and double barrier tunneling
Marcos Calçada, José T. Lunardi, Luiz A. Manzoni
In this work we revisit the Salecker-Wigner-Peres clock formalism and show that it can be directly applied to the phenomenon of tunneling. Then we apply this formalism to the deter…
Gravitation and the Local Symmetry Group of Spacetime
M. Calcada, J. G. Pereira
According to general relativity, the interaction of a matter field with gravitation requires the simultaneous introduction of a tetrad field, which is a field related to translatio…
Angular Momentum and Energy-Momentum Densities as Gauge Currents
M. Calcada, J. G. Pereira
If we replace the general spacetime group of diffeomorphisms by transformations taking place in the tangent space, general relativity can be interpreted as a gauge theory, and in p…
