Breakdown of Quantum Chaos in the Staggered-Field XXZ Chain: Confinement and Meson Formation

Julia Wildeboer, Marton Lajer, Robert M. Konik

Confinement produces mesonic bound states, but their existence alone does not determine the statistical organization of the many-body spectrum. We investigate this connection in th…

Hamiltonian parameter inference from resonant inelastic x-ray scattering with active learning

Marton K. Lajer, Xin Dai, Kipton Barros +3

Identifying model Hamiltonians is a vital step toward creating predictive models of materials. Here, we combine Bayesian optimization with the EDRIXS numerical package to infer Ham…

Witnessing Quantum Entanglement Using Resonant Inelastic X-ray Scattering

Tianhao Ren, Yao Shen, Marton Lajer +9

Although entanglement is both a central ingredient in our understanding of quantum many-body systems and an essential resource for quantum technologies, we only have a limited abil…

Nuclear matter in 1+1 dimensions

Robert M. Konik, Marton Lajer, Robert D. Pisarski +1

We review the solution of QCD in two spacetime dimensions. Following the analysis of Baluni, for a single flavor the model can be analyzed using Abelian bosonization. The theory ca…

Approaching the Self-Dual Point of the Sinh-Gordon model

Robert Konik, Márton Lájer, Giuseppe Mussardo

One of the most striking but mysterious properties of the sinh-Gordon model (ShG) is the self-duality of its -matrix, of which there is no trace in its Lagra…

Leading exponential finite size corrections for non-diagonal form factors

Zoltan Bajnok, Marton Lajer, Balint Szepfalvi +1

We derive the leading exponential finite volume corrections in two dimensional integrable models for non-diagonal form factors in diagonally scattering theories. These formulas are…

Field theoretical derivation of Lüscher's formula and calculation of finite volume form factors

Zoltán Bajnok, János Balog, Márton Lájer +1

We initiate a systematic method to calculate both the finite volume energy levels and form factors from the momentum space finite volume two-point function. By expanding the two po…

Truncated Hilbert space approach to the 2d theory

Z. Bajnok, M. Lajer

We apply the massive analogue of the truncated conformal space approach to study the two dimensional theory in finite volume. We focus on the broken phase and determine the…
