Tailoring interaction ranges in atom arrays
T. Botzung, G. Creutzer, C. Sayrin +1
We introduce a method to synthetically engineer the range of dipolar interactions in tweezer atom arrays by effectively modifying the modes of the electromagnetic vacuum with far-d…
Error recovery protocols within metastable Decoherence-Free Subspaces
Thomas Botzung, Eliana Fiorelli
Open quantum systems governed by quantum master equations can exhibit quantum metastability, where decoherence-free subspaces (DFS) remain approximately invariant for long transien…
Numerical observation of Nagaoka ferromagnetism
Thomas Botzung, Pierre Nataf
We provide numerical evidence of the Nagaoka's theorem in the Fermi-Hubbard model on various cluster geometries, such as the square, the honeycomb and the triangul…
Robustness and measurement-induced percolation of the surface code
Thomas Botzung, Michael Buchhold, Sebastian Diehl +1
We examine the robustness of a logical qubit in the planar surface code subject to 'measurement-errors', i.e., to local Pauli measurements at known positions. This yields a measure…
Exact Diagonalization of Fermi-Hubbard Models
Thomas Botzung, Pierre Nataf
We show how to perform exact diagonalizations of Fermi-Hubbard models on -site clusters separately in each irreducible representation ({irrep}) of $\mathrm{SU}(…
Comparing bipartite entropy growth in open-system matrix-product simulation methods
Guillermo Preisser, David Wellnitz, Thomas Botzung +1
The dynamics of one-dimensional quantum many-body systems is often numerically simulated with matrix-product states (MPSs). The computational complexity of MPS methods is known to…
Engineered dissipation induced entanglement transition in quantum spin chains: from logarithmic growth to area law
Thomas Botzung, Sebastian Diehl, Markus Müller
Recent theoretical work has shown that the competition between coherent unitary dynamics and stochastic measurements, performed by the environment, along wavefunction trajectories…
Large Random Arrowhead Matrices: Multifractality, Semi-Localization, and Protected Transport in Disordered Quantum Spins Coupled to a Cavity
Jérôme Dubail, Thomas Botzung, Johannes Schachenmayer +2
We provide an exact solution of large random arrowhead Hamiltonians with diagonal disorder, a minimal model for inhomogeneously broadened quantum emitters coupled to a cavity mode.…
Dark state semilocalization of quantum emitters in a cavity
Thomas Botzung, David Hagenmüller, Stefan Schütz +3
We study a disordered ensemble of quantum emitters collectively coupled to a lossless cavity mode. The latter is found to modify the localization properties of the "dark" eigenstat…
Effects of energy extensivity on the quantum phases of long-range interacting systems
Thomas Botzung, David Hagenmüller, Guido Masella +4
We investigate the ground state properties of one-dimensional hard-core bosons interacting via a variable long-range potential using the density matrix renormalization group. We de…
One-dimensional extended Hubbard model with soft-core potential
Thomas Botzung, Guido Pupillo, Pascal Simon +2
We investigate the phase diagram of a variant of the one-dimensional extended Hubbard model where particles interact via a finite-range soft-shoulder potential. Using Density…
Algebraic Localization from Power-Law Interactions in Disordered Quantum Wires
Thomas Botzung, Davide Vodola, Piero Naldesi +3
We analyze the effects of disorder on the correlation functions of one-dimensional quantum models of fermions and spins with long-range interactions that decay with distance …
