Fitness landscape for quantum state tomography from neutron scattering
Tymoteusz Tula, Jorge Quintanilla, Gunnar Möller
Recently, a direct connection between static structure factors and quantum ground states for two-spin interaction Hamiltonians was proven. This suggests the possibility of quantum…
Tensor Network Python (TeNPy) version 1
Johannes Hauschild, Jakob Unfried, Sajant Anand +27
TeNPy (short for 'Tensor Network Python') is a python library for the simulation of strongly correlated quantum systems with tensor networks. The philosophy of this library is to a…
Acoustic lattice instabilities at the magneto-structural transition in FeTe
K. Guratinder, E. Chan, E. E. Rodriguez +7
FeTe undergoes a first-order tetragonal to monoclinc structural transition at T K, breaking the C lattice symmetry and simultaneously breaking time…
Energy minimization of paired composite fermion wave functions in the spherical geometry
Greg J. Henderson, Gunnar Möller, Steven H. Simon
We perform the energy minimization of the paired composite fermion (CF) wave functions, proposed by Möller and Simon (MS) [PRB 77, 075319 (2008)] and extended by Yutushui and Mross…
Symmetry fractionalization, mixed-anomalies and dualities in quantum spin models with generalized symmetries
Heidar Moradi, Ömer M. Aksoy, Jens H. Bardarson +1
We investigate the gauging of higher-form finite Abelian symmetries and their sub-groups in quantum spin models in spatial dimensions and 3. Doing so, we naturally uncover ga…
Topological Holography: Towards a Unification of Landau and Beyond-Landau Physics
Heidar Moradi, Seyed Faroogh Moosavian, Apoorv Tiwari
We outline a holographic framework that attempts to unify Landau and beyond-Landau paradigms of quantum phases and phase transitions. Leveraging a modern understanding of symmetrie…
Origin and dynamics of umbrella states in rare-earth iron garnets
Bruno Tomasello, Dan Mannix, Stephan Geprägs +1
Rare-earth iron garnets FeO are fascinating insulators with very diverse magnetic phases. Their strong potential in spintronic devices has encouraged a renewal…
Relationship between the ground-state wave function of a magnet and its static structure factor
Jorge Quintanilla
We state and prove two theorems about the ground state of magnetic systems described by very general Heisenberg-type models and discuss their implications for magnetic neutron scat…
Self-similarity of spectral response functions for fractional quantum Hall states
Bartholomew Andrews, Gunnar Möller
Spectral response functions are central quantities in the analysis of quantum many-body states, since they describe the response of many-body systems to external perturbations and…
Metastable antiphase boundary ordering in CaFeO
H. Lane, E. E. Rodriguez, H. C. Walker +11
CaFeO is an antiferromagnet exhibiting two magnetic orders which shows regions of coexistence at some temperatures. Using a Green's function formalism, we model…
Stability, phase transitions, and numerical breakdown of fractional Chern insulators in higher Chern bands of the Hofstadter model
Bartholomew Andrews, Titus Neupert, Gunnar Möller
The Hofstadter model is a popular choice for theorists investigating the fractional quantum Hall effect on lattices, due to its simplicity, infinite selection of topological flat b…
Magnetic-field-controlled spin fluctuations and quantum criticality in Sr3Ru2O7
C. Lester, S. Ramos, R. S. Perry +8
When the transition temperature of a continuous phase transition is tuned to absolute zero, new ordered phases and physical behaviour emerge in the vicinity of the resulting quantu…
Magnetic surface reconstruction in the van-der-Waals antiferromagnet FeTe
C. Trainer, M. Songvilay, N. Qureshi +9
FeTe is a two dimensional van der Waals antiferromagnet that becomes superconducting on anion substitution on the Te site. The parent phase of FeTe is sensitive to…
Geometric frustration on the trillium lattice in a magnetic metal-organic framework
Johnathan M. Bulled, Joseph A. M. Paddison, Andrew Wildes +6
In the dense metal-organic framework Na[Mn(HCOO)], Mn ions () occupy the nodes of a `trillium' hyperkagome net. We show that this material exhibits a vari…
Local density of states of the interacting resonant level model at zero temperature
Gonzalo Camacho, Peter Schmitteckert, Sam T. Carr
We present results of the impurity local density of states of the interacting resonant level model at zero temperature. We concentrate on low-energy properties and predominantly us…
Taming the sign problem of the finite density Hubbard model via Lefschetz thimbles
Maksim Ulybyshev, Christopher Winterowd, Savvas Zafeiropoulos
We study the sign problem in the Hubbard model on the hexagonal lattice away from half-filling using the Lefschetz thimbles method. We identify the saddle points, reduce their amou…
Lefschetz thimbles decomposition for the Hubbard model on the hexagonal lattice
Maksim Ulybyshev, Christopher Winterowd, Savvas Zafeiropoulos
We propose a framework to study the properties of the Lefschetz thimbles decomposition for lattice fermion models approaching the thermodynamic limit. The proposed set of algorithm…
