Percolation and Dissolution of Borromean Networks

no code yet • 27 Jun 2022

Inspired by experiments on topologically linked DNA networks, we consider the connectivity of Borromean networks, in which no two rings share a pairwise-link, but groups of three rings form inseparable triplets.

Lattice calculation of the short and intermediate time-distance hadronic vacuum polarization contributions to the muon magnetic moment using twisted-mass fermions

no code yet • 30 Jun 2022

We present a lattice determination of the leading-order hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment, $a_{\mu}^{\rm HVP}$, in the so-called short and intermediate time-distance windows, $a_{\mu}^{SD}$ and $a_{\mu}^W$, defined by the RBC/UKQCD Collaboration [1].

Precision measurement of the microwave dielectric loss of sapphire in the quantum regime with parts-per-billion sensitivity

no code yet • 29 Jun 2022

We demonstrate the method with measurements of EFG sapphire, from which we infer a bulk loss tangent of $62(7) \times 10^{-9}$ and a substrate-air interface loss tangent of $12(2) \times 10^{-4}$.

NLTS Hamiltonians from good quantum codes

no code yet • 27 Jun 2022

The NLTS (No Low-Energy Trivial State) conjecture of Freedman and Hastings [2014] posits that there exist families of Hamiltonians with all low energy states of non-trivial complexity (with complexity measured by the quantum circuit depth preparing the state).

Gravitational-wave inference for eccentric binaries: the argument of periapsis

no code yet • 28 Jun 2022

Gravitational waves from binary black hole mergers have allowed us to directly observe stellar-mass black hole binaries for the first time, and therefore explore their formation channels.
