Pivoting through the chiral-clock family
Nick G. Jones, Abhishodh Prakash, Paul Fendley
The Onsager algebra, invented to solve the two-dimensional Ising model, can be used to construct conserved charges for a family of integrable -state chiral clock models. We show…
Out-of-equilibrium full counting statistics in Gaussian theories of quantum magnets
Riccardo Senese, Jacob H. Robertson, Fabian H. L. Essler
We consider the probability distributions of the subsystem (staggered) magnetization in ordered and disordered models of quantum magnets in D dimensions. We focus on Heisenberg ant…
From the XXZ chain to the integrable Rydberg-blockade ladder via non-invertible duality defects
Luisa Eck, Paul Fendley
Strongly interacting models often possess "dualities" subtler than a one-to-one mapping of energy levels. The maps can be non-invertible, as apparent in the canonical example of Kr…
A simple theory for quantum quenches in the ANNNI model
Jacob H. Robertson, Riccardo Senese, Fabian H. L. Essler
In a recent numerical study by Haldar et al. (Phys. Rev. X 11, 031062) it was shown that signatures of proximate quantum critical points can be observed at early and intermediate t…
Ballistic macroscopic fluctuation theory
Benjamin Doyon, Gabriele Perfetto, Tomohiro Sasamoto +1
We introduce a new universal framework describing fluctuations and correlations in quantum and classical many-body systems, at the Euler hydrodynamic scale of space and time. The f…
Real-Time Evolution in the Hubbard Model with Infinite Repulsion
Elena Tartaglia, Pasquale Calabrese, Bruno Bertini
We consider the real-time evolution of the Hubbard model in the limit of infinite coupling. In this limit the Hamiltonian of the system is mapped into a number-conserving quadratic…
