Interpretable Augmented Physics-Based Model for Estimation and Tracking
State-space estimation and tracking rely on accurate dynamical models to perform well. However, obtaining an vaccurate dynamical model for complex scenarios or adapting to changes in the system poses challenges to the estimation process. Recently, augmented physics-based models (APBMs) appear as an appealing strategy to cope with these challenges where the composition of a small and adaptive neural network with known physics-based models (PBM) is learned on the fly following an augmented state-…

Generalized Symmetries Phase Transitions with Local Quantum Fields
Symmetries are important guiding principle for phase transitions. We systematically construct field theory models with local quantum fields that exhibit the following phase transitions: (1) different symmetry protected topological (SPT) phases with generalized symmetries; (2) different symmetry enriched topological (SET) phases with generalized symmetries differ by symmetry fractionalizations; (3) spontaneously broken generalized symmetries, where the unbroken phases can have nontrivial SPT or …

Bose-Hubbard Model on a Honeycomb Superlattice: Quantum Phase Transitions and Lattice Effects
We investigate the ground-state and finite-temperature phase diagrams of the Bose-Hubbard model on a honeycomb superlattice. The interplay between the superlattice potential depth $Δ/t$ and the onsite interaction $U/t$ gives rise to three distinct quantum phases at zero temperature: a superfluid phase, a Mott insulator I phase with unit filling on each site, and a Mott insulator II phase characterized by density imbalance-double occupancy on one sublattice and vacancy on the other at unit fill…

I nearly gave my credit card to a legit-looking Maine business, until I noticed their “privacy policy” linked to Wikipedia. That’s not laziness but AI-generated HTML vibecoded into place without review. And a lot more can go wrong than a missing legal page.

Its good to have many tests in your R package, but it can be a pain to debug some failing tests when it happens. {lazytest} for the rescue: only rerun the failing tests, until they pass: #RStats

Several significant pieces of the House-approved spending bill are at risk of falling out of the legislation as it moves through the Senate
At least one of Thune’s members is already publicly floating that his party should be willing to directly overrule Senate Parlementarian MacDonough on the reconciliation bill.
In a tweet last month, Sen. Mike Lee (R-Utah) wrote on X that “disagreeing with the Senate parliamentarian may be warranted if the parliamentarian gives bad advice, and …

Fractionalization as an alternate to charge ordering in electronic insulators
Incompressible insulating phases of electronic systems at partial filling of a lattice are often associated with charge ordering that breaks lattice symmetry. The resulting phases have an enlarged unit cell with an effective integer filling. Here we explore the possibility of insulating states - which we dub "Quantum Charge Liquids" (QCL) - at partial lattice filling that preserve lattice translation symmetry. Such QCL phases must necessarily either have gapped fractionally charged excitations …
