Hamiltonian and primary constraints of new general relativity
Daniel Blixt, Manuel Hohmann, Christian Pfeifer
We derive the kinematic Hamiltonian for the so-called "new general relativity" class of teleparallel gravity theories, which is the most general class of theories whose Lagrangian…
Revisiting Stability in New General Relativity
Sebastian Bahamonde, Daniel Blixt, Konstantinos F. Dialektopoulos +1
We study the degrees of freedom in New General Relativity -- flat and metric compatible family of theories -- around the Minkowski background in a gauge invariant manner. First, we…
The Hamilton equations in teleparallel gravity and in New General Relativity
Francesco Bajardi, Daniel Blixt, Salvatore Capozziello
We derive the Hamiltonian function for extended teleparallel theories of gravity in their covariant formulation. In particular, we present the Hamiltonian for gravity and Ne…
Canonical Vielbeins for General Relativity: D + 1 Decomposition and Constraint Analysis
Joakim Flinckman, Daniel Blixt
We provide a self-contained derivation of the Hamiltonian formulation of General Relativity in vielbein variables in dimensions. Starting from the Einstein--Hilbert action…
On the gauge fixing in the Hamiltonian analysis of general teleparallel theories
Daniel Blixt, Manuel Hohmann, Christian Pfeifer
The covariant formulation of teleparallel gravity theories must include the spin connection, which has 6 degrees of freedom. One can, however, always choose a gauge such that the s…
Degrees of Freedom of New General Relativity I: Type 2, Type 3, Type 5, and Type 8
Kyosuke Tomonari, Daniel Blixt
We investigate the degrees of freedom of new general relativity. This theory is a three-parameter theory and is classified into nine irreducible types according to the rotation sym…
