Sign-optimized Quantum Monte Carlo
Julius S. Herz, Robin Schäfer, MatÃas G. Gonzalez +1
The sign problem breaks the polynomial scaling of Quantum Monte Carlo methods. We alleviate it by rotation of the local basis of the Hilbert space, such that the phase of off-diago…
Dissipative Stabilization of Floquet-Engineered Many-Body Order
Shreyas Raman, Robin Schäfer, Robin Schafer +3
Floquet driving underlies Hamiltonian and gate engineering, and produces dynamical orders with no equilibrium counterpart. These phenomena are, however, transient in well-isolated…
Hall-on-Toric: Descendant Laughlin state in the chiral toric code
Robin Schäfer, Claudio Chamon, Chris R. Laumann
We demonstrate that the chiral toric code -- the quintessential model of topological order -- hosts additional, emergent topological phases when perturbed: descendan…
Thermodynamics of the Heisenberg antiferromagnet on the maple-leaf lattice
Robin Schäfer, Paul L. Ebert, Noah Hassan +3
We study the Heisenberg antiferromagnet on the maple-leaf lattice using several numerical approaches, focusing on the numerical linked-cluster expansion (NLCE), which exhibits an u…
Probing Hilbert space fragmentation using controlled dephasing
Dominik Vuina, Robin Schäfer, David M. Long +1
Dynamical constraints in many-body quantum systems can lead to Hilbert space fragmentation, wherein the system's evolution is restricted to small subspaces of Hilbert space called…
DanceQ: High-performance library for number-conserving bases
Robin Schäfer, David J. Luitz
The complexity of quantum many-body problems scales exponentially with the size of the system, rendering any finite size scaling analysis a formidable challenge. This is particular…
