Neural quantum states in condensed matter: advances, best practices, and prospects
Jonas B. Rigo, Björn J. Wurst, Rajah Nutakki +2
Neural quantum states provide flexible variational representations of quantum many-body wave functions by combining neural-network parametrizations with Monte Carlo sampling. In th…
Ground-state phases of Heisenberg models on the body-centered cubic lattice
Rajah P. Nutakki, Filippo Vicentini
Simulating low-temperature properties of three-dimensional frustrated quantum magnets is challenging due to the sign problem and the system sizes required to mitigate substantial f…
Comparing Symmetrized Determinant Neural Quantum States for the Hubbard Model
Louis Sharma, Ahmedeo Shokry, Rajah Nutakki +3
Accurate simulations of the Hubbard model are crucial to understanding strongly correlated phenomena, where small energy differences between competing orders demand high numerical…
Coupling quantum spin ice to matter on the centered pyrochlore lattice
Rajah P. Nutakki, Sylvain Capponi, Ludovic D. C. Jaubert +1
The low-energy physics of quantum spin ice is known to support an emergent form of quantum electrodynamics (QED), where magnetic monopoles exist and the fine structure constant is…
Design principles of deep translationally-symmetric neural quantum states for frustrated magnets
Rajah P. Nutakki, Ahmedeo Shokry, Filippo Vicentini
Deep neural network quantum states have emerged as a leading method for studying the ground states of quantum magnets. Successful architectures exploit translational symmetry, but…
The Classical Heisenberg Model on the Centred Pyrochlore Lattice
Rajah P. Nutakki, Ludovic D. C. Jaubert, Lode Pollet
The centred pyrochlore lattice is a novel geometrically frustrated lattice, realized in the metal-organic framework Mn(ta) (arXiv:2203.08780) where the basic unit of spins is a…
Frustration on a centred pyrochlore lattice in metal-organic frameworks
Rajah Nutakki, Richard Röß-Ohlenroth, Dirk Volkmer +6
Geometric frustration inhibits magnetic systems from ordering, opening a window to unconventional phases of matter. The paradigmatic frustrated lattice in three dimensions to host…
SU(4) Heisenberg model on the honeycomb lattice with exchange-frustrated perturbations: implications for twistronics and Mott insulators
W. M. H. Natori, R. Nutakki, R. G. Pereira +1
The SU(4)-symmetric spin-orbital model on the honeycomb lattice was recently studied in connection to correlated insulators such as the Mott insulator BaCuSbO$_…
Electronic structure of the candidate 2D Dirac semimetal SrMnSb2: a combined experimental and theoretical study
S. V. Ramankutty, J. Henke, A. Schiphorst +15
SrMnSb is suggested to be a magnetic topological semimetal. It contains square, 2D Sb planes with non-symmorphic crystal symmetries that could protect band crossings, offering…
