Forecast And Analysis Of The Cosmological Redshift Drift

Lazcoz Sáez, Ruth; Leanizbarrutia Alonso, Iker; Salzano, Vincenzo (Springer, 2018-01-08)

The cosmological redshift drift could lead to the next step in high-precision cosmic geometric observations, becoming a direct and irrefutable test for cosmic acceleration. In order to test the viability and possible ...

Pre-Inflation From The Multiverse: Can It Solve The Quadrupole Problem In The Cosmic Microwave Background?

Morais, João; Bouhmadi López, Mariam; Krämer, Manuel; Robles Pérez, Salvador (Springer, 2018-03-21)

We analyze a quantized toy model of a universe undergoing eternal inflation using a quantum-field-theoretical formulation of the Wheeler-DeWitt equation. This so-called third quantization method leads to the picture that ...

An analytic superfield formalism for tree superamplitudes in D=10 and D=11

Bandos, Igor (Springer, 2018-05-16)

Tree amplitudes of 10D supersymmetric Yang-Mills theory (SYM) and 11D supergravity (SUGRA) are collected in multi-particle counterparts of analytic on-shell superfields. These have essentially the same form as their chiral ...

Quantum work statistics, Loschmidt echo and information scrambling

Chenu, A.; Egusquiza Egusquiza, Iñigo Luis; Molina-Vilaplana, J.; Del Campo, A. (Nature Publishing, 2018-08-22)

A universal relation is established between the quantum work probability distribution of an isolated driven quantum system and the Loschmidt echo dynamics of a two-mode squeezed state. When the initial density matrix is ...

Black hole solutions in mimetic Born-Infeld gravity

Chen, Che-Yu; Bouhmadi López, Mariam; Chen, Pisin (Springer, 2018-01-23)

The vacuum, static, and spherically symmetric solutions in the mimetic Born-Infeld gravity are studied. The mimetic Born-Infeld gravity is a reformulation of the Eddington-inspired-Born-Infeld (EiBI) model under the mimetic ...

What if gravity becomes really repulsive in the future?

Albarran, Imanol; Bouhmadi López, Mariam; Morais, João (Springer, 2018-03-24)

The current acceleration of the Universe is one of themost puzzling issues in theoretical physics nowadays. We are far from giving an answer in this letter to the question of its nature. Yet, with the observations we have ...

Entanglement loss in molecular quantum-dot qubits due to interaction with the environment

Blair, Enrique P.; Tóth, Géza; Lent, Craig S. (IOP Publishing, 2018-05-16)

We study quantum entanglement loss due to environmental interaction in a condensed matter system with a complex geometry relevant to recent proposals for computing with single electrons at the nanoscale. We consider a ...

Measurement of the Tau Michel Parameters (Eta)Over-Bar and Xi Kappa in the Radiative Leptonic Decay Tau(-) -> L(-)Nu(Tau)(Nu)Over-Bar(L)Gamma

(Oxford University Press, 2018-02)

We present a measurement of the Michel parameters of the tau lepton, (eta) over bar and xi kappa, in the radiative leptonic decay tau(-) -> l(-)nu(tau)(nu) over bar (l)gamma using 711 fb(-1) of collision data collected ...

Quantum entanglement in de Sitter space with a wall and the decoherence of bubble universes

Albrecht, Andreas; Kanno, Sugumi; Sasaki, Misao (American Physical Society, 2018-04-30)

We study the effect of a bubble wall on the entanglement entropy of a free massive scalar field between two causally disconnected open charts in de Sitter space. We assume there is a delta-functional wall between the open ...

Anisotropic Inflation With Derivative Couplings

Holland, Jonathan; Kanno, Sugumi; Zavala, Ivonne (American Physical Society, 2018-05-29)

We study anisotropic power-law inflationary solutions when the inflaton and its derivative couple to a vector field. This type of coupling is motivated by D-brane inflationary models, in which the inflaton, and a vector ...
