Spin correlations in two-particle systems: a pedagogically motivated comparison of computational approaches
S. Martins-Filho
In this work we present a pedagogically motivated analysis of spin-correlation calculations in a quantum system composed of two spin- particles. Rather than aiming at new phys…
Covariant quantization of the Einstein-Hilbert theory in first-order form
S. Martins-Filho
We present a covariant quantization of the first-order formulation of the Einstein-Hilbert theory using the path integral and BV formalisms. In this approach, the metric …
Quantum gravity and matter fields in a general background gauge
J. Frenkel, S. Martins-Filho
We analyse the gauge-dependence of the effective action in an interacting quantum theory of gravitational and matter fields. An explicit off-shell result is obtained in a general b…
Supergravity with Lagrange Multiplier Fields in 2 + 1 Dimensions
D. G. C. McKeon, F. T. Brandt, J. Frenkel +1
We examine the first-order Einstein-Cartan (EC) action in 2+1 dimensions, including a cosmological term and its supersymmetric extension. In this setting the spin connection can be…
Equivalence of first and second order formulations of the Einstein-Hilbert theory
F. T. Brandt, J. Frenkel, S. Martins-Filho +1
We derive a general relation between the background effective actions, which directly proves that the two formulations of the Einstein-Hilbert theory with background fields are equ…
A Renormalizable Model of Quantized Gravitational and Matter Fields
D. G. C. McKeon, F. T. Brandt, J. Frenkel +1
A Lagrange multiplier field can be used to restrict radiative corrections to the Einstein-Hilbert action to one-loop order. This result is employed to show that it is possible to c…
