Quantum critical dynamical response of the twisted Kitaev spin chain
Uliana E. Khodaeva, Dmitry L. Kovrizhin, Johannes Knolle
The dynamical structure factor of the transverse field Ising model (TFIM) shows universal power-law divergence at its quantum critical point, signatures of which have been arguably…

Disorder-Free Localization for Benchmarking Quantum Computers
Jad C. Halimeh, Uliana E. Khodaeva, Dmitry L. Kovrizhin +2
Disorder-free localization (DFL) is a phenomenon as striking as it appears to be simple: a translationally invariant state evolving under a disorder-free Hamiltonian failing to the…

Quantum simulation of the 1D Fermi-Hubbard model as a lattice-gauge theory
Uliana E. Khodaeva, Dmitry L. Kovrizhin, Johannes Knolle
The Fermi-Hubbard model is one of the central paradigms in the physics of strongly-correlated quantum many-body systems. Here we propose a quantum circuit algorithm based on the $\…
