Every Poincaré gauge theory is conformal: a compelling case for dynamical vector torsion

Posted by dbos Cambridge

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Will Barker, Michael Hobson, Anthony Lasenby, Yun-Cherng Lin, Zhiyuan Wei | Summary: The Poincar’e gauge theory (PGT) of gravity provides a viable formulation of general relativity (Einstein-Cartan theory), and a popular model-building framework for modified gravity with torsion. Notoriously, however, the PGT terms which propagate vector torsion […]

Event structure sculpts neural population dynamics in the lateral entorhinal cortex

Posted by dbos NTNU

Kavli Affiliate: Edvard Moser and May-Britt Moser | Authors: Benjamin R Kanter, Christine M Lykken, May-Britt Moser and Edvard I. Moser | Summary: Our experience of the world is a continuous stream of events which must be segmented and organized simultaneously at multiple timescales. The neural mechanisms underlying this process remain unknown. Here, we simultaneously […]

Electron-Beam Writing of Atomic-Scale Reconstructions at Oxide Interfaces

Posted by dbos Delft

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Greta Segantini, Chih-Ying Hsu, Carl Willem Rischau, Patrick Blah, Mattias Matthiesen | Summary: The epitaxial growth of complex oxides enables the production of high-quality films, yet substrate choice is restricted to certain symmetry and lattice parameters, thereby limiting the technological applications of epitaxial oxides. In comparison, […]

Challenges to the Lambda CDM Cosmology

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: Observations of the cosmic microwave backgroundradiation are described to remarkable accuracy by the six-parameterLambda CDM cosmology. However, the key ingredients of this model, namely dark matter, dark energy and cosmic inflation are not understood at a fundamental level. It is […]
