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…
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…
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…
Quenching the CME via the gravitational anomaly and holography
Karl Landsteiner, Esperanza Lopez, Guillermo Milans del Bosch
In the presence of a gravitational contribution to the chiral anomaly, the chiral magnetic effect induces an energy current proportional to the square of the temperature in equilib…
A simple holographic scenario for gapped quenches
Esperanza Lopez, Guillermo Milans del Bosch
We construct gravitational backgrounds dual to a family of field theories parameterized by a relevant coupling. They combine a non-trivial scalar field profile with a naked singula…
Holographic Quenches with a Gap
Emilia da Silva, Esperanza Lopez, Javier Mas +1
In order to holographically model quenches with a gapped final hamiltonian, we consider a gravity-scalar theory in anti-de Sitter space with an infrared hard wall. We allow a time…
