Spinors from pure spinors

Niren Bhoja, Kirill Krasnov

We propose and develop a new method to classify orbits of the spin group in the space of its semi-spinors. The idea is to consider spinors as being built as a line…

The stellar mass function of quiescent galaxies in 2 < z < 2.5 protoclusters

Adit H. Edward, Michael L. Balogh, Yannick M. Bahe +21

We present an analysis of the galaxy stellar mass function (SMF) of 14 known protoclusters between in the COSMOS field, down to a mass limit of M$_{\odot…

Planetary nebulae populations in the haloes of nearby massive early-type galaxies

J. Hartke, M. Arnaboldi, O. Gerhard +8

Planetary nebulae (PNe) are excellent tracers of the metal-poor haloes of nearby early-type galaxies. They are commonly used to trace spatial distribution and kinematics of the hal…

Tripartite quantum Rabi model with trapped Rydberg ions

Thomas J. Hamlyn, Chi Zhang, Igor Lesanovsky +1

We investigate a tripartite quantum Rabi model (TQRM) wherein a bosonic mode concurrently couples to two spin- particles through a spin-spin interaction, resulting in a spin-s…

Scalable simulation of non-equilibrium quantum dynamics via classically optimised unitary circuits

Luke Causer, Felix Jung, Asimpunya Mitra +2

The advent of near-term digital quantum computers could offer us an exciting opportunity to investigate quantum many-body phenomena beyond that of classical computing. To make the…

Area-metric gravity revisited

Johanna N. Borissova, Bianca Dittrich, Kirill Krasnov

Area metrics are an intriguing generalization of length metrics which appears in several quantum-gravity approaches. We describe the space of diffeomorphism-invariant area-metric a…
