Quantum work statistics, Loschmidt echo and information scrambling
(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 ...
Phantom dark ghost in Einstein–Cartan gravity
(Springer, 2017-05-03)
A class of dynamical dark energy models is constructed through an extended version of fermion fields corresponding to phantom dark ghost spinors, which are spin 1/2 with mass dimension 1. We find that if these spinors ...
Adaptation to criticality through organizational invariance in embodied agents
(Nature Publishing, 2018-05-16)
Many biological and cognitive systems do not operate deep within one or other regime of activity. Instead, they are poised at critical points located at phase transitions in their parameter space. The pervasiveness of ...
Lewis Acid Properties of Tetrel Tetrafluorides—The Coincidence of the -Hole Concept with the QTAIM Approach
(MDPI, 2017-02)
Tetrel bond is analysed for a series of ZF(4) (Z = C, Si, Ge) complexes with one and two NH3 or AsH3 ligands. The MP2/aug-cc-pVTZ calculations were performed and supported by results of the Quantum Theory of Atoms in ...
Vacuum state of the Dirac field in de Sitter space and entanglement entropy
(Springer, 2017-03-13)
We compute the entanglement entropy of a free massive Dirac field between two causally disconnected open charts in de Sitter space. We first derive the Bunch-Davies vacuum mode functions of the Dirac field. We find there ...
Infective endocarditis in hypertrophic cardiomyopathy A multicenter, prospective, cohort study
(Lippincott Williams & Wilkins, 2016-06)
Infective endocarditis (IE) complicating hypertrophic cardiomyopathy (HCM) is a poorly known entity. Although current guidelines do not recommend IE antibiotic prophylaxis (IEAP) in HCM, controversy remains.This study ...
Creating stable Floquet–Weyl semimetals by laser-driving of 3D Dirac materials
(Nature Publishing, 2017-01-17)
Tuning and stabilizing topological states, such as Weyl semimetals, Dirac semimetals or topological insulators, is emerging as one of the major topics in materials science. Periodic driving of many-body systems offers a ...
Increased Calcium-Sensing Receptor Immunoreactivity in the Hippocampus of a Triple Transgenic Mouse Model of Alzheimer's Disease
(Frontiers Media, 2017-02-16)
The Calcium-Sensing Receptor (CaSR) is a G-protein coupled, 7-transmembrane domain receptor ubiquitously expressed throughout the body, brain including. The role of CaSR in the CNS is not well understood; its expression ...
Multicenter prospective study on the burden of rotavirus gastroenteritis in children less than 3 years of age in Spain
(Biomed Central, 2016-10-10)
Background: Rotavirus is acknowledged as an important cause of paediatric gastroenteritis worldwide. In Spain, comprehensive data on the burden of rotavirus disease was lacking.
Methods: A prospective, multicenter, ...
