When quantizing conformal dilaton gravity, there is a conformal anomaly which starts at two-loop order. This anomaly stems from evanescent operators on the divergent parts of the effective action. The general form of the finite counterterm, whic[...]![]()

Guerrero Roman, Merce ; Rubiera García, Diego ; Saez-Chillon Gomez, Diego | Amer Physical Soc | 2020-12-16Constant roll inflation is analyzed in the presence of multiscalar fields which are assumed to be described by a constant roll rate each. The different cases are studied and the corresponding potentials are reconstructed. The exact solutions are[...]![]()

In the framework of Einstein-Yang-Mills theories, we study the gauge Lorentz group and establish a particular correspondence between this case and a certain class of theories with torsion within RiemannCartan space-times. This relation is specia[...]![]()

It has been recently shown that the presence of a vector field over cosmological scales could explain the observed accelerated expansion of the Universe without introducing either new scales or unnatural initial conditions in the early Universe,[...]![]()

Einstein-Cartan theory is an extension of the standard formulation of general relativity characterized by a nonvanishing torsion. The latter is sourced by the matter fields via the spin tensor, and its effects are expected to be important at ver[...]![]()

We present a detailed study of the cosmological evolution in general vector-tensor theories of gravity without potential terms. We consider the evolution of the vector field throughout the expansion history of the Universe and carry out a classi[...]![]()

Cross sections for positron and electron collisions with an analog of the purine nucleobases: Indole
Chiari, Luca ; Zecca, Antonio ; Blanco Ramos, Francisco ; García, Gustavo ; Brunger, M.J. | Amer Physical Soc | 2015-01-26Quantitative information about positron and electron collisions with nucleobases is required in charged-particle track simulations to accurately model and assess any radiation damage at the subcellular level in biological systems. However, scatt[...]![]()

Fraile Prieto, Luis Mario ; Vedia Fernández, María Victoria ; otros, ... | Amer Physical Soc | 2020-08-18Decay spectroscopy of the long-lived states in Tl-186 has been performed at the ISOLDE Decay Station at ISOLDE, CERN. The a decay from the low-spin (2(-)) state in Tl-186 was observed for the first time and a half-life of 3.4(-0.)(4)(+0.5) s was[...]![]()

We improve the calculations of the ?????? decay within the context of meson chiral Lagrangians. We use a chiral unitary approach for [...]![]()

Starting from the chiral perturbation theory Lagrangian, but keeping different masses for the charged and neutral mesons (m_u ? m_d), and using a previously developed nonperturbative unitary scheme that generates the lightest meson-meson resonan[...]![]()

The decoherence interpretation of quantum measurements is applied to Wigner's-friend experiments. A framework in which all the experimental outcomes arise from unitary evolutions is proposed. Within it, a measurement is not completed until an un[...]![]()

We determine the values of the one- and two-loop low energy constants appearing in the SU(2) Chiral Perturbation Theory calculation of pion-pion scattering. For this we use a recent and precise sum rule determination of some scattering lengths a[...]![]()

We compute the error threshold for the semion code, the companion of the Kitaev toric code with the same gauge symmetry group Z(2). The application of statistical mechanical mapping methods is highly discouraged for the semion code, since the co[...]![]()

Vaveliuk, Pablo ; Martínez Matos, Óscar ; Ren, Yu-Xuan ; Lu, Rong-De | Amer Physical Soc | 2017-06-23A full propagation analysis on both fold-type and cusp-type caustic optical beams under various setups of obstructions is theoretically and experimentally performed. It is demonstrated that the self-healing property of caustic optical beams that[...]![]()

We study the effect of a Chern-Simons term on the electrically charged and spinning solitons of several U(1) gauged models in 2 + 1 dimensions. These are vortices of complex scalar field theories, both with and without symmetry breaking dynamics[...]![]()
