Topological phase transition in a symmetric blockade structure
Johannes Mögerle, Simon Fell, Tobias F. Maier +4
We present a numerical study of a blockade Hamiltonian with a local symmetry. For such models, the existence of a topologically ordered ground state has been proven…
Excitation gap of a blockade structure with topological order
Simon Fell, Tobias F. Maier, Hans Peter Büchler +1
Mathematically rigorous statements on the spectral gap of quantum many-body systems in the thermodynamic limit are notoriously difficult to prove -- yet they are of fundamental imp…
Diagonalization of the Landau Hamiltonian with a Periodic Potential via a Galerkin Projection Method and Applications to Topological Band Properties
Rafael Antonio Lainez Reyes, Benjamin Stamm, Hans Peter Büchler
In this paper, we study the numerical computation of eigenfunctions of the Landau Hamiltonian with a periodic potential. We propose a spectral method using the eigenfunctions of th…
Quench Spectroscopy for Two-Dimensional Spin Models with Power-Law Interactions
Katharina Brechtelsbauer, Hans Peter Büchler
In this paper, we analytically compute the quench dynamics of simple product states that evolve under a spin-1/2 XY-model with power-law interactions in a staggered magnetic field.…
Robust detection of an entanglement transition in the projective transverse field Ising model
Felix Roser, Etienne M. Springer, Hans Peter Büchler +1
We propose a scalable and noise-resilient protocol for the detection of the entanglement transition in a projective version of the transverse field Ising model. Entanglement transi…
Quantum Simulation of Spin-1 XXZ-Heisenberg Models and the Haldane Phase with Dysprosium
Katharina Brechtelsbauer, Johannes Mögerle, Hans Peter Büchler
Dysprosium atoms have proven to be a promising platform for quantum simulation due to their strong magnetic moment and high tunability of interactions. In this work, we propose Dys…
