Coupling induced emergent topology in a two-leg fermionic ladder
We investigate the ground state properties of spinless fermions on a two leg ladder, by allowing the nearest-neighbour hopping dimerization in one leg and uniform hopping in the other. In the non-interacting limit, we find that, at half-filling, the system exhibits robust topological behavior if the inter-leg hopping is allowed. As a result, a topological phase transition occurs as a function of the inter-leg hopping. When the inter-leg interaction is turned on, the topological phase survives, …

Day 3: Octavia Butler.
Incredibly dark, graphic, and disturbing near-future science fiction, which has proved absolutely prophetic. In the 1990's she was writing about a charismatic Conservative Christian and white nationalist president elected in 2024, and the horrors his paramilitary followers would unleash, including forced labor & indoctrination camps. Did I mention those books include ebikes & pseudo-cellphones too? Characters fleeing north from a disastrous social collapse in Loss Angeles? This is "The Parable of the Sower" and "The Parable of the Talents" and the later was tragically rushed to an end because of Butler's declining health.
Her work deals unflinchingly with racism and the darker parts of society, and to those who might say "her depiction of social collapse is overblown," I'd say that while it's not literally the world we live in, it's *effectively* the world that the poorest of us live in. If you're a homeless undocumented latinx person in LA right now, I'm not sure how meaningfully different your world is from the one she depicts.
Her work comes with a strong content warning for lots of things, including racial violence, sexual abuse and slavery, including of children, animal harm, etc., so it's not for everyone. Reading it in 2023 was certainly an incredible trip. Her politics are really cool though; with explicit pro-LGBTQ themes and tinges of what might today be considered #SolarPunk.

A regret minimization approach to fixed-point iterations

A regret minimization approach to fixed-point iterations
We propose a conversion scheme that turns regret minimizing algorithms into fixed point iterations, with convergence guarantees following from regret bounds. The resulting iterations can be seen as a grand extension of the classical Krasnoselskii--Mann iterations, as the latter are recovered by converting the Online Gradient Descent algorithm. This approach yields new simple iterations for finding fixed points of non-self operators. We also focus on converting algorithms from the AdaGrad family…

Today, #TimorLeste 🇹🇱 becomes the #ASEAN’s 11th member when the 47th summit begins in Kuala Lumpur later. 🎉
To mark this occasion, I decided to create a mock Philippine historical marker commemorating the body owing to the

'Your Party later said in a post on [!!!??] X: "For those who joined under the previous system last week, please be assured your data and membership is secure and will be migrated across. There is nothing more for you to do at this stage."'
Which, together with Corbyn's ref to the roadmap, which Zarah was following is as close as she'll get to being vindicated.
Let's hope that's an end to it.

Jeremy Corbyn sorry for 'confusion' as new party membership launched
The former Labour leader admits the new party has faced some "fraught days in the last week".

Today's adventure: the train departs, and a minute later I notice that the lamps outside are moving in the wrong direction. The following thoughts pass through my mind in express speed:
• Illusion? Nope, definitely going front from where I'm sitting.
• Did I confuse directions before taking the seat? Nope, we're definitely moving south.
• Did I really take the wrong train?! I think it departed at the right time, what's the likeliness…
Then I suddenly realize that it's apparently taking the roundabout route, through #Poznań Franowo rather than Poznań Wschód.

Inyo County, on the eastern side of the Sierra Nevada, has two hospitals.
In a matter of weeks it may be down to one, local and state officials say.
Southern Inyo Healthcare District -- a 37-bed hospital in Lone Pine -- had eight days of cash on hand as of Sept.12, chief executive Dr. Kevin Flanigan told CalMatters.
Local officials have sent a letter asking Gov. Gavin Newsom for an emergency $3 million to stabilize its finances through the end of the year,
but absent s…

With just days of cash left, Inyo County hospital nears crisis point
The financial crisis at Southern Inyo Healthcare District comes as rural hospitals nationwide face rising costs and federal Medicaid cuts.
