Ab initio artificial intelligence: Future research of Materials Genome Initiative
Materials Genome Engineering Advances, Volume 1, Issue 2, December 2023., 2023 As the field of materials discovery evolves, a shift from traditional trial‐and‐error methods to data‐driven and AI‐driven approaches is gradually taking precedence. This perspective introduces the emerging research field of ab initio AI, which utilizes AI techniques to improve ab initio computational methods.

An identity in the Bethe subalgebra of C[Sn]$\mathbb {C}[\mathfrak {S}_n]$
Proceedings of the London Mathematical Society, Volume 127, Issue 5, Page 1247-1267, November 2023., 2023 Abstract As part of the proof of the Bethe ansatz conjecture for the Gaudin model for gln$\mathfrak {gl}_n$, Mukhin, Tarasov, and Varchenko described a correspondence between inverse Wronskians of polynomials and eigenspaces of the Gaudin Hamiltonians. Notably, this correspondence afforded the first proof of the Shapiro–Shapiro conjecture.

Harnessing the Quantum Behavior of Spins on Surfaces
Advanced Materials, Volume 35, Issue 27, July 6, 2023., 2023 By incorporating electron spin resonance capability in spin‐polarized scanning tunneling microscopy, quantum states of individual spins on surfaces can be initialized, controlled, and read out. Individual spins and artificial spin structures built atom‐by‐atom provide new platforms for sensing magnetic interactions, performing quantum operations, and ...

The subsystem quantum chemistry program Serenity
WIREs Computational Molecular Science, Volume 13, Issue 3, May/June 2023., 2023 Exploiting the subsystem structure of molecules and molecular aggregates is at the heart of the SERENITY program. The new version of this code features highly efficient modules for coupled response properties of aggregates, but also projection‐based DLPNO‐CC‐in‐DFT embedding and several other features optimized for subsystem quantum chemistry ...

Spectral Determinant of the Two‐Photon Quantum Rabi Model
Annalen der Physik, Volume 535, Issue 3, March 2023., 2023 The determination of the exact spectrum of quantum systems with a single continuous degree of freedom is only possible in very few cases, because polynomial ansatz functions do not exist. Here it is demonstrated that the Bargmann Hilbert space allows the computation of the spectral determinant of the quantum Rabi model with non‐linear (two‐photon ...

Bethe states of the XXZ spin-12 chain with arbitrary boundary fields
Nuclear Physics B, 2015 Based on the inhomogeneous T−Q relation constructed via the off-diagonal Bethe Ansatz, the Bethe-type eigenstates of the XXZ spin-12 chain with arbitrary boundary fields are constructed.

Transfer matrices for AdS3/CFT2
Journal of High Energy Physics, 2022 We work out the algebraic Bethe ansatz for the worldsheet theory of the AdS 3 × S 3 × T 4 superstring, and use it to derive the transfer matrices for fundamental particles and bound states of the string and mirror model.

MONTE–CARLO THERMODYNAMIC BETHE ANSATZ [PDF]
International Journal of Modern Physics B, 2006 We introduce a Monte–Carlo simulation approach to thermodynamic Bethe ansatz (TBA). We exemplify the method on one-particle integrable models, which include a free boson and a free fermions systems along with the scaling Lee–Yang model (SLYM). It is confirmed that the central charges and energies are correct to a very good precision, typically 0.1% or

Supersymmetric Vacua and Bethe Ansatz [PDF]
Nuclear Physics B - Proceedings Supplements, 2009 An announcement of some results of a longer paper where the supersymmetric vacua of two dimensional N=2 susy gauge theories with matter are shown to be in one-to-one correspondence with the eigenstates of integrable spin chain Hamiltonians. The Heisenberg spin chain is mapped to the two dimensional U(N) theory with fundamental hypermultiplets, the XXZ ...

LARGE-N AND BETHE ANSATZ [PDF]
Modern Physics Letters A, 2004 We describe an integrable model, related to the Gaudin magnet, and its relation to the matrix model of Brézin, Itzykson, Parisi and Zuber. Relation is based on Bethe ansatz for the integrable model and its interpretation using orthogonal polynomials and saddle point approximation.
