Comportamiento bosónico de pares de fermiones con interacción de contacto 1D
(2019-12)
Para determinar cuán bosónico es el comportamiento de pares de fermiones distinguibles interactuantes con interacción de contacto en un sistema unidimensional continuo se propusieron dos modelos: partículas libres y ...
Non-relativistic quantum field theory of Verlinde's emergent entropic gravity
(Academic Press Inc Elsevier Science, 2020-01)
Non relativistic quantum field theory propagators are indispensable tools in nuclear physics and condensed matter theory. Here we apply them to gravitation, that is, discuss a non relativistic quantum field theory for ...
First-order density matrices in one dimension for independent fermions and impenetrable bosons in harmonic traps
(Elsevier Science, 2007-01)
To complement existing knowledge of the density matrix γF (x, y) of independent fermions for N particles in one dimension under harmonic confinement, the corresponding matrix γIB (x, y) for impenetrable bosons is given for ...
Current correlation functions from a bosonized theory in 3 / 2 + 1 dimensions
(Springer, 2020-02-14)
Within the context of a bosonized theory, we evaluate the current-current correlation functions corresponding to a massive Dirac field in 2 + 1 dimensions, which is constrained to a spatial half-plane. The boundary conditions ...
Reflected entropy, symmetries and free fermions
(Springer, 2020-05)
Exploiting the split property of quantum field theories (QFTs), a notion of von Neumann entropy associated to pairs of spatial subregions has been recently proposed both in the holographic context — where it has been argued ...
Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC
(Elsevier Science, 2013-08)
Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H → γγ , H → Z Z∗ → 4 and H → W W ∗ → ν ν. The results are based on the complete ...
Field interaction and anomalies in astrophysical and cosmological phenomena
(Springer/Plenum Publishers, 2000-12)
The WKB expansion of bosonic and fermionic interacting fields in general curved spacetimes is computed. The explicit expression of the loss of energy in terms of macroscopic quantities like densities and velocities, according ...
Supersymmetric mixed boundary conditions in AdS2 and DCFT1 marginal deformations
(Springer, 2020-03)
We consider different supersymmetric mixed boundary conditions for scalar and fermionic fields in AdS2, searching for the dual description of a family of interpolating Wilson Loops in ABJM theory. The family, which ...
