Einstein–Cartan cosmologies [PDF]

Annals of Physics, 2019
Cosmologies based on General Relativity encompassing an anti-symmetric connection (torsion) can display nice desirable features as the absence of the initial singularity and the possibility of inflation in the early stage of the universe. After briefly reviewing the standard approach to the cosmology with torsion, we generalize it to demonstrate that ...

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

Einstein's grandchildren [PDF]

EMBO reports, 2010
The new German government has boldly promised to “lead Germany to first place in the world in education, science and research.” Howy Jacobs explores this promise and whether it will lure Einstein's grandchildren back across the pond.

Directional Flow of Confined Polaritons in CrSBr

Advanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Einstein e a teoria de caos quântico

Revista Brasileira de Ensino de Física
O trabalho de Einstein intitulado Sobre o teorema quântico de Sommerfeld e de Epstein [1,2], publicado em 1917, propõe uma generalização da regra de quantização de Bohr, Sommerfeld e Epstein para sistemas multidimensionais integráveis.

Nothing for Money and Your Work for Free: Internships and the Marketing of Higher Education

tripleC: Communication, Capitalism & Critique, 2015
American universities have significantly increased their marketing expenditures over the last decade. The high cost of education, reductions in government funding, and precipitous declines in the traditional college-aged population (18-21 year olds) are

Bright solitary waves and non-equilibrium dynamics in atomic Bose-Einstein condensates [PDF]

, 2012
In this thesis we investigate the static properties and non-equilibrium dynamics of bright solitary waves in atomic Bose-Einstein condensates in the zero-temperature limit, and we investigate the non-equilibrium dynamics of a driven atomic Bose-Einstein ...

Emergent Spin Supersolids in Frustrated Quantum Materials

Advanced Materials, EarlyView.
This review highlights developments in the study of spin super‐solids in frustrated quantum materials. Advanced experimental characterizations and computational studies enable a comprehensive understanding of the driving mechanisms of spin super‐solidity in various layered transition‐metal compounds, bridging materials, experiments, and theory aspects.
