DESI Strong Lens Foundry II: DESI Spectroscopy for Strong Lens Candidates
We present the Dark Energy Spectroscopic Instrument (DESI) Strong Lensing Secondary Target Program. This is a spectroscopic follow-up program for strong gravitational lens candidates found in the DESI Legacy Imaging Surveys footprint. Spectroscopic redshifts for the lenses and lensed source are crucial for lens modeling to obtain physical parameters. The spectroscopic catalog in this paper consists of 73 candidate systems from the DESI Early Data Release (EDR). We have confirmed 20 strong lensi…

"All I can tell you is what people from Altrincham who were at the protest had to say. They are keen to stress, often unprompted, that they are not racist - they are angry and concerned.
"They cite alarming statistics about asylum seekers accused of sexual assault and rape - statistics that I could not find any evidence to support. They claim that asylum seekers in this hotel are 'robbing shops' - something that the police told me they have 'no knowledge' of.&q…

A new rung on the ladder: exploring topological frustration towards two dimensions
Topological frustration arises when boundary conditions impose geometric frustration in a quantum system, creating delocalized defects in the ground states and profoundly altering the low-energy properties. While previous studies have been concerned with one-dimensional systems, showing that the ground state structure can be described in terms of quasiparticle excitations, the two-dimensional setting remains unexplored. We address this gap by studying a three-legged antiferromagnetic quantum Is…
