Investigations on Effective Electromagnetic and Gravitational Scenarios
M. G. Campos, L. P. R. Ospedal, J. A. Helayël-Neto
The work aims effective and low-dimensional systems. Some different contexts involving gravitational and electromagnetic interactions are investigated. The electromagnetic one appr…
Tensor Renormalization Group for interacting quantum fields
Manuel Campos, German Sierra, Esperanza Lopez
We present a new tensor network algorithm for calculating the partition function of interacting quantum field theories in 2 dimensions. It is based on the Tensor Renormalization Gr…
Effective theories and non-minimal couplings in low-dimensional systems
M. G. Campos, L. P. R. Ospedal
Dimensionality aspects of non-minimal electromagnetic couplings are investigated. By means of the Foldy-Wouthuysen transformation, we attain (non-)relativistic interactions related…
Integrability and scattering of the boson field theory on a lattice
Manuel Campos, German Sierra, Esperanza Lopez
A free boson on a lattice is the simplest field theory one can think of. Its partition function can be easily computed in momentum space. However, this straightforward solution hid…
Quantum corrected gravitational potential beyond monopole-monopole interactions
G. P. de Brito, M. G. Campos, L. P. R. Ospedal +1
We investigate spin- and velocity-dependent contributions to the gravitational inter-particle potential. The methodology adopted here is based on the expansion of the effective act…
Tensor renormalization group in bosonic field theory
Manuel Campos, German Sierra, Esperanza Lopez
We compute the partition function of a massive free boson in a square lattice using a tensor network algorithm. We introduce a singular value decomposition (SVD) of continuous matr…
