ABJM Wilson loops in the Fermi gas approach

The matrix model of ABJM theory can be formulated in terms of a Fermi gas in an external potential. We show that, in this formalism, vevs of Wilson...

Metal-enriched galactic outflows shape the mass-metallicity relatio...

The gas-phase metallicity of low-mass galaxies increases with increasing stellar mass ($M_\ast$) and is nearly constant for high-mass galaxies. The...

Testing the chemical tagging technique with open clusters

Context. Stars are born together from giant molecular clouds and, if we assume that the priors were chemically homogeneous and well-mixed, we expec...

This paper presents a novel clustering concept that is based on jointly learned nonlinear transforms (NTs) with priors on the information loss and the discrimination. We introduce a clustering principle that is based on evaluation of a parametric ...

Security proof for a simplified BB84-like QKD protocol

The security of quantum key distribution (QKD) has been proven for different protocols, in particular for the BB84 protocol. It has been shown that...

Observability of hydrogen-rich exospheres in Earth-like exoplanets

(Abridged) The existence of an extended neutral hydrogen exosphere around small planets can be used as an evidence for the presence of water in the...

Inherently stable effective field theory for dark energy and modifi...

The growing wealth of cosmological observations places increasingly more stringent constraints on dark energy and alternative gravity models. Parti...

Discovery of a soft X-ray 8 mHz QPO from the accreting millisecond ...

In this paper, we report on the analysis of the peculiar X-ray variability displayed by the accreting millisecond X-ray pulsar IGR J00291+5934 in a...

Noise in optical quantum memories based on dynamical decoupling of ...

Long-lived optical quantum memories are of great importance for scalable distribution of entanglement over remote networks (e.g. quantum repeaters)...

Are we living near the center of a local void?

The properties of the cosmic microwave background (CMB) temperature and polarisation anisotropies measured by a static, off-centered observer locat...

Feeding the fire: Tracing the mass-loading of 10^7 K galactic outfl...

Galactic outflows regulate the amount of gas galaxies convert into stars. However, it is difficult to measure the mass outflows remove because they...

Early-time spectra of supernovae and their precursor winds: the lum...

We present the first quantitative spectroscopic modeling of an early-time supernova that interacts with its progenitor wind. Using the radiative tr...

Universality in the 2D Ising model and conformal invariance of ferm...

It is widely believed that the celebrated 2D Ising model at criticality has a universal and conformally invariant scaling limit, which is used in d...

Quantum Algebra

We claim that the equivalence between grt1 in depth two modulo higher depth and the cohomology of the space of two-loop graphs is not a coincidence. For this, let us recall one further graph complex, GC2.

Filtrations on graph complexes and the Grothendieck-Teichmüller Lie...

We establish an isomorphism between the Grothendieck-Teichm\"uller Lie algebra $\mathfrak{grt}_1$ in depth two modulo higher depth and the cohomolo...

We have presented a method to generate fingerprint vectors for data exhibiting associative properties. It is based on diffusion processes over a domain graph and shows how to make dimensionality reduction efficient and robust. The numerical vector...

Diffusion Fingerprints

We introduce, test and discuss a method for classifying and clustering data modeled as directed graphs. The idea is to start diffusion processes fr...
