GCVE-BCP-08 - GCVE GNA Directory File (draft)
Following various discussions and the meeting at FOSDEM, we will create the GCVE-BCP-08 describing the directory JSON format. GCVE-BCP-08 - GCVE GNA Directory File Status of This Document This document defines GCVE-BCP-08, which specifies the structure and semantics of the GCVE GNA Directory File. This file gcve.json enumerates known GCVE Numbering Authorities (GNAs) and associated metadata used by the GCVE ecosystem. Scope The GCVE GNA Directory File is a JSON document containing an array…

We gaan even alle puntjes op de i zetten. Im t verleden zag je dat afspraken te open waren.
Met andere woorden: het regeerakkoord wordt flink dichtgetimmerd.
Hoe wil je dan nog kunnen onderhandelingen voor meerderheden?

Abstract: We investigate the fate of a one-dimensional lattice superfluid formed by hard-core bosons, aka `atoms' (alternatively, a free spinless Fermi sea) subjected to nearest-neighbor attractive Hubbard-like interactions only in subgroups of two sites. The system, as expected, stabilizes a fluid of dimerized molecules at large attractive interactions. However, the composite molecules have an effective meek hopping scale and dominant repulsive interactions solely due to virtual quantum fluctuations. Interestingly, at an intermediate attractive potential, the system realizes a phase-separated region where the system is in an absorbing state. We show that this phase-separated region is due to an emergent attractive interaction between the dimers which leads to a local charge-density wave puddle where particles effectively cluster with local half-filling. Moreover the molecular superfluid gets spontaneously charge-ordered in the addition of an unpaired atom, reflecting the extreme sensitivity of the system to the existence of lone atoms. Using density-matrix renormalization group studies and effective low-energy Hamiltonians, we isolate the quantum processes to uncover the physics behind molecule formation in a strongly interacting one-dimensional system.
