Interacting Dirac magnons in the van der Waals ferromagnet CrBr
Saikat Banerjee, Stephan Humeniuk
We study the effects of magnon-magnon interactions in the two-dimensional van der Waals ferromagnet CrBr focusing on its honeycomb lattice structure. Motivated by earlier theor…
Simulating the Transverse Field Ising Model on the Kagome Lattice using a Programmable Quantum Annealer
Pratyankara Narasimhan, Stephan Humeniuk, Ananda Roy +1
The presence of competing interactions due to geometry leads to frustration in quantum spin models. As a consequence, the ground state of such systems often displays a large degene…
Autoregressive neural Slater-Jastrow ansatz for variational Monte Carlo simulation
Stephan Humeniuk, Yuan Wan, Lei Wang
Direct sampling from a Slater determinant is combined with an autoregressive deep neural network as a Jastrow factor into a fully autoregressive Slater-Jastrow ansatz for variation…
Numerically exact mimicking of quantum gas microscopy for interacting lattice fermions
Stephan Humeniuk, Yuan Wan
A numerical method is presented for reproducing fermionic quantum gas microscope experiments in equilibrium. By employing nested componentwise direct sampling of fermion pseudo-den…
Thermal Kosterlitz-Thouless transitions in the long-range ferromagnetic quantum Ising chain revisited
Stephan Humeniuk
For the inverse square long-range ferromagnetic Ising chain in a transverse field, the thermal phase boundary of the floating Kosterlitz-Thouless phase is obtained for several valu…
Tuning the two-step melting of magnetic orders in a dipolar kagome spin ice by quantum fluctuations
Yao Wang, Stephan Humeniuk, Yuan Wan
Complex magnetic orders in frustrated magnets may exhibit rich melting processes when the magnet is heated toward the paramagnetic phase. We show that one may tune such melting pro…
Quantum state tomography on a plaquette in the 2D Hubbard model
Stephan Humeniuk
Motivated by recent quantum gas microscope experiments for fermions in optical lattices, we present proof of principle calculations showing that it is possible to obtain the comple…
Full Counting Statistics for Interacting Fermions with Determinantal Quantum Monte Carlo Simulations
Stephan Humeniuk, Hans Peter Büchler
We present a method for computing the full probability distribution function of quadratic observables for the Fermi-Hubbard model within the framework of determinantal quantum Mont…
Quantum Monte Carlo Study of Long-Range Transverse-Field Ising Models on the Triangular Lattice
Stephan Humeniuk
Motivated by recent experiments with a Penning ion trap quantum simulator, we perform numerically exact Stochastic Series Expansion quantum Monte Carlo simulations of long-range tr…
Quantum Monte Carlo calculation of entanglement Renyi entropies for generic quantum systems
Stephan Humeniuk, Tommaso Roscilde
We present a general scheme for the calculation of the Renyi entropy of a subsystem in quantum many-body models that can be efficiently simulated via quantum Monte Carlo. When the…
