Higher genus twistor spaces and the celestial torus
This paper studies novel four-dimensional integrable field theories that are deformations of self-dual Yang-Mills. They are engineered by considering holomorphic Chern-Simons and BF type theories on covers of twistor space obtained by pulling back the vector bundle $\mathcal{O}(1)^2\to\mathbb{CP}^1$ to hyperelliptic or elliptic curves. Compactifying to 4d yields an integrable theory, which in the examples I study, are determined to leading order. The form of the higher-order corrections are boo…

Spontaneous formation of subsystem and bath under accordion-type driving
Floquet modulations often yield effective Hamiltonians not easily accessible in traditional time-dependent systems, which brings opportunities for exploring novel physics of quantum dynamics. We investigate a Floquet system exhibiting translational symmetry at any fixed time but the spatial periodicity is time-dependent. Such a system is a natural platform for studying thermalization and novel dynamical structures. We find that the single-particle Hilbert space spontaneously develops a structur…

Actively Learning to Coordinate in Convex Games via Approximate Correlated Equilibrium
Correlated equilibrium generalizes Nash equilibrium by allowing a central coordinator to guide players' actions through shared recommendations, similar to how routing apps guide drivers. We investigate how a coordinator can learn a correlated equilibrium in convex games where each player minimizes a convex cost function that depends on other players' actions, subject to convex constraints without knowledge of the players' cost functions. We propose a learning framework that learns an approximat…

Genus stabilization for the homology of moduli spaces of orbit-framed curves with symmetries-I
In a previous paper, arXiv:1301.4409, we showed that the moduli space of curves C with a G-symmetry (that is, with a faithful action of a finite group G), having a fixed generalized homological invariant, is irreducible if the genus g' of the quotient curve C' : = C/G satisfies g'>>0. Interpreting this result as stabilization for the 0-th homology group of the moduli space of curves with G-symmetry, we begin here a program for showing stabilization for all the homology groups of these spaces,…

This Saturday, millions of people are going to say no, and insist that every American has a right to dissent.
It’s going to be big
— there will be enormous rallies in major cities, and smaller but still meaningful ones in towns around the country.
There will be families, and dogs, and people in silly costumes.
They’re going to march, and stand together, and listen to speeches, and hold up signs
Trump and his allies will spin their absurd conspiracy theories,…

Ahead of No Kings Protest, Trump and GOP Try to Delegitimize All Dissent
There is no such thing as genuine progressive public opinion, and therefore mass and mobilized opposition to Trump doesn't count.

We had lunch today with longtime friends who have a time share condo in Florida, where they have spent time every January going back 20 years. The husband doesn't think it's a big deal to continue going. The wife doesn't want to go back as she thinks boycotting U.S. travel is the right thing to do. It was obviously a sore spot between them, so we kinda changed the subject. But not before we made it clear that we won't set foot in the USA as long as the orange moron is president.

Findings of MEGA: Maths Explanation with LLMs using the Socratic Method for Active Learning
This paper presents an intervention study on the effects of the combined methods of (1) the Socratic method, (2) Chain of Thought (CoT) reasoning, (3) simplified gamification and (4) formative feedback on university students' Maths learning driven by large language models (LLMs). We call our approach Mathematics Explanations through Games by AI LLMs (MEGA). Some students struggle with Maths and as a result avoid Math-related discipline or subjects despite the importance of Maths across many fie…

Quantum Deception: Honey-X Deception using Quantum Games
In this paper, we develop a framework for deception in quantum games, extending the Honey-X paradigm from classical zero-sum settings into the quantum domain. Building on a view of deception in classical games as manipulation of a player's perception of the payoff matrix, we formalize quantum deception as controlled perturbations of the payoff Hamiltonian subject to a deception budget. We show that when victims are aware of possible deception, their equilibrium strategies surprisingly coincide …

The announcement this week that Elon Musk’s SpaceX is purchasing
$17 billion in wireless spectrum
has sent jitters through an industry now eyeing the prospect of
Elon-style disruptions to a market
long dominated by Verizon, AT&T and T-Mobile.
The new bandwidth is destined for use by SpaceX’s satellite service, Starlink.
