Conformal Data for the Wilson-Fisher CFT in -Dimensional Spacetime from Exact Diagonalization and Matrix Product States on the Fuzzy Sphere
Arjun Dey, Loic Herviou, Christopher Mudry +2
We study at zero temperature a microscopic quantum spin-1 model on the fuzzy sphere that realizes the Wilson-Fisher conformal field theory (CFT) in -dimensional space…
Conformal Data for the O(3) Wilson-Fisher Conformal Field Theory from Fuzzy Sphere Realization of the Quantum Rotor Model
Arjun Dey, Loic Herviou, Christopher Mudry +1
We present a model for strongly interacting fermions with internal O(3) symmetry on the fuzzy-sphere that (i) preserves the rotational symmetry of the fuzzy sphere and (ii) undergo…
A Novel Perspective on Ideal Chern Bands with Strong Short-Range Repulsion: Applications to Correlated Metals, Superconductivity, and Topological Order
Patrick H. Wilhelm, Andreas M. Läuchli, Mathias S. Scheurer
Motivated by recent experiments on correlated van der Waals materials, including twisted and rhombohedral graphene and twisted WSe, we perform an analytical and numerical study…
Quantum Spin Dynamics Due to Strong Kitaev Interactions in the Triangular-Lattice Antiferromagnet CsCeSe
Tao Xie, S. Gozel, Jie Xing +8
The extraordinary properties of the Kitaev model have motivated an intense search for new physics in materials that combine geometrical and bond frustration. In this work, we emplo…
Non-coplanar magnetism, topological density wave order and emergent symmetry at half-integer filling of moiré Chern bands
Patrick H. Wilhelm, Thomas C. Lang, Mathias S. Scheurer +1
Twisted double- and mono-bilayer graphene are graphene-based moiré materials hosting strongly correlated fermions in a gate-tunable conduction band with a topologically non-trivial…
Emergent XY* transition driven by symmetry fractionalization and anyon condensation
Michael Schuler, Louis-Paul Henry, Yuan-Ming Lu +1
Anyons in a topologically ordered phase can carry fractional quantum numbers with respect to the symmetry group of the considered system, one example being the fractional charge of…
Diagnosing weakly first-order phase transitions by coupling to order parameters
Jonathan D'Emidio, Alexander A. Eberharter, Andreas M. Läuchli
The hunt for exotic quantum phase transitions described by emergent fractionalized degrees of freedom coupled to gauge fields requires a precise determination of the fixed point st…
Studying Continuous Symmetry Breaking using Energy Level Spectroscopy
Alexander Wietek, Michael Schuler, Andreas M. Läuchli
Tower of States analysis is a powerful tool for investigating phase transitions in condensed matter systems. Spontaneous symmetry breaking implies a specific structure of the energ…
Phase diagram of interacting spinless fermions on the honeycomb lattice
Sylvain Capponi
Fermions hopping on a hexagonal lattice represent one of the most active research field in condensed matter since the discovery of graphene in 2004 and its numerous applications. A…
Phase diagram of interacting spinless fermions on the honeycomb lattice: A comprehensive exact diagonalization study
Sylvain Capponi, Andreas M. Läuchli
We investigate the phase diagram of spinless fermions with nearest and next-nearest neighbour density-density interactions on the honeycomb lattice at half-filling. Using Exact Dia…
Entanglement Entropies of the quarter filled Hubbard model
Pasquale Calabrese, Fabian H. L. Essler, Andreas M. Lauchli
We study Renyi and von Neumann entanglement entropies in the ground state of the one dimensional quarter-filled Hubbard model with periodic boundary conditions. We show that they e…
Momentum-Space Entanglement Spectrum of Bosons and Fermions with Interactions
Rex Lundgren, Jonathan Blair, Martin Greiter +3
We study the momentum space entanglement spectra of bosonic and fermionic formulations of the spin-1/2 XXZ chain with analytical methods and exact diagonalization. We investigate t…
Entanglement spectrum of the Heisenberg XXZ chain near the ferromagnetic point
Vincenzo Alba, Masudul Haque, Andreas M. Laeuchli
We study the entanglement spectrum (ES) of a finite XXZ spin 1/2 chain in the limit Δ-> -1^+ for both open and periodic boundary conditions. At Δ=-1 (ferromagnetic point) the model…
The ALPS project: open source software for strongly correlated systems
F. Alet, P. Dayal, A. Grzesik +15
We present the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application programs for the…
