Betti Functionals as a Probe for Cosmic Topology

Ralf Aurich, Frank Steiner

The question of the global topology of the Universe (cosmic topology) is still open. In the CDM concordance model it is assumed that the space of the Universe possesses the triv…

The variance of the CMB temperature gradient: a new signature of a multiply connected Universe

Ralf Aurich, Thomas Buchert, Martin J. France +1

In this work we investigate the standard deviation of the Cosmic Microwave Background (CMB) temperature gradient field as a signature for a multiply connected nature of the Univers…

Determining our peculiar velocity from the aberration in the cosmic microwave background

Ralf Aurich, David Reinhardt

The motion of our solar system relative to the CMB rest frame leads to subtle distortions in the observed CMB sky map due to the aberration effect. Usually the corresponding peculi…

On the concordance of cosmological data in the case of the generalized Chaplygin gas

Ralf Aurich, Sven Lustig

The generalized Chaplygin gas cosmology provides a prime example for the class of unified dark matter models, which substitute the two dark components of the standard cosmological…

Early-Matter-Like Dark Energy and the Cosmic Microwave Background

Ralf Aurich, Sven Lustig

Early-matter-like dark energy is defined as a dark energy component whose equation of state approaches that of cold dark matter (CDM) at early times. Such a component is an ingredi…

Sensing of single nuclear spins in random thermal motion with proximate nitrogen-vacancy centers

M. Bruderer, P. Fernández-Acebal, R. Aurich +1

Nitrogen-vacancy (NV) centers in diamond have emerged as valuable tools for sensing and polarizing spins. Motivated by potential applications in chemistry, biology, and medicine, w…
