Matrix Product Operator Encodings of the Magnus Expansion and Dyson Series
Victor Vanthilt, Maarten Van Damme, Jutho Haegeman +2
We introduce a matrix product operator (MPO) encoding of the Magnus expansion and the Dyson series for one-dimensional quantum lattice models with time-dependent Hamiltonians. The…
Parallel implementation of the Density Matrix Renormalization Group method achieving a quarter petaFLOPS performance on a single DGX-H100 GPU node
Andor Menczer, Maarten van Damme, Alan Rask +5
We report cutting edge performance results for a hybrid CPU-multi GPU implementation of the spin adapted ab initio Density Matrix Renormalization Group (DMRG) method on current sta…
Efficient higher-order matrix product operators for time evolution
Maarten Van Damme, Jutho Haegeman, Ian McCulloch +1
We introduce a systematic construction of higher-order matrix product operator (MPO) approximations of the time evolution operator for generic (short and long range) one-dimensiona…
Anatomy of Dynamical Quantum Phase Transitions
Maarten Van Damme, Jean-Yves Desaules, Zlatko Papić +1
Global quenches of quantum many-body models can give rise to periodic dynamical quantum phase transitions (DQPTs) directly connected to the zeros of a Landau order parameter (OP).…
Dynamical quantum phase transitions in spin- quantum link models
Maarten Van Damme, Torsten V. Zache, Debasish Banerjee +2
Dynamical quantum phase transitions (DQPTs) are a powerful concept of probing far-from-equilibrium criticality in quantum many-body systems. With the strong ongoing experimental dr…
Simulating chiral spin liquids with projected entangled-pair states
Juraj Hasik, Maarten Van Damme, Didier Poilblanc +1
Doubts have been raised on the representation of chiral spin liquids exhibiting topological order in terms of projected entangled pair states (PEPSs). Here, starting from a simple…
Momentum-resolved time evolution with matrix product states
Maarten Van Damme, Laurens Vanderstraeten
We introduce a method based on matrix product states (MPS) for computing spectral functions of (quasi) one-dimensional spin chains, working directly in momentum space in the thermo…
Achieving the quantum field theory limit in far-from-equilibrium quantum link models
Jad C. Halimeh, Maarten Van Damme, Torsten V. Zache +2
Realizations of gauge theories in setups of quantum synthetic matter open up the possibility of probing salient exotic phenomena in condensed matter and high-energy physics, along…
Suppressing nonperturbative gauge errors in the thermodynamic limit using local pseudogenerators
Maarten Van Damme, Julius Mildenberger, Fabian Grusdt +2
With recent progress in quantum simulations of lattice-gauge theories, it is becoming a pressing question how to reliably protect the gauge symmetry that defines such models. In a…
Reliability of lattice gauge theories in the thermodynamic limit
Maarten Van Damme, Haifeng Lang, Philipp Hauke +1
Although gauge invariance is a postulate in fundamental theories of nature such as quantum electrodynamics, in quantum-simulation implementations of gauge theories it is compromise…
Towards the continuum limit of a d quantum link Schwinger model
Torsten V. Zache, Maarten Van Damme, Jad C. Halimeh +2
The solution of gauge theories is one of the most promising applications of quantum technologies. Here, we discuss the approach to the continuum limit for gauge theories reg…
Quasiparticle origin of dynamical quantum phase transitions
Jad C. Halimeh, Maarten Van Damme, Valentin Zauner-Stauber +1
Considering nonintegrable quantum Ising chains with exponentially decaying interactions, we present matrix product state results that establish a connection between low-energy quas…
Quasiparticles in quantum spin chains with long-range interactions
Laurens Vanderstraeten, Maarten Van Damme, Hans Peter Büchler +1
We study quasiparticle excitations for quantum spin chains with long-range interactions using variational matrix product state techniques. It is confirmed that the local quasiparti…
