Tetrahedral Core in a Sea of Competing Magnetic Phases in Graphene
Maxime Lucas, Arnaud Ralko, Andreas Honecker +1
We demonstrate the emergence of a robust tetrahedral magnetic ground state in monolayer graphene doped to the van Hove singularity (vHS). This noncoplanar, gapped spin configuratio…
Electronic structure and transport in materials with flat bands: 2D materials and quasicrystals
Guy Trambly de Laissardière, Somepalli Venkateswarlu, Ahmed Missaoui +9
In this review, we present recent works on materials whose common point is the presence of electronic bands of very low dispersion, called "flat bands", which are due to specific a…
Machine learning of phases and structures for model systems in physics
Djenabou Bayo, Burak Çivitcioğlu, Joseph J Webb +2
The detection of phase transitions is a fundamental challenge in condensed matter physics, traditionally addressed through analytical methods and direct numerical simulations. In r…
Phase determination with and without deep learning
Burak Çivitcioğlu, Rudolf A. Römer, Andreas Honecker
Detection of phase transitions is a critical task in statistical physics, traditionally pursued through analytic methods and direct numerical simulations. Recently, machine-learnin…
ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase
M. Ozerov, M. Maksymenko, J. Wosnitza +6
Magnetic excitations in the strong-leg quantum spin ladder compound (CHN)CuBr (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…
Analysis of the phase transition for the Ising model on the frustrated square lattice
A. Kalz, A. Honecker, M. Moliner
We analyze the phase transition of the frustrated - Ising model with antiferromagnetic nearest- and strong next-nearest neighbor interactions on the square lattice. Using…
Quantum disordered ground state for hard-core bosons on the frustrated square lattice
A. Kalz, A. Honecker, S. Fuchs +1
We investigate the phase diagram of hard-core bosons on a square lattice with competing interactions. The hard-core bosons can be represented also by spin-1/2 operators and the mod…
Magnetic properties of the Hubbard model on kagome stripes
O. Derzhko, M. Maksymenko, J. Richter +2
We consider the one-orbital -site repulsive Hubbard model on two kagome-like chains, both of which yield a completely dispersionless (flat) one-electron band. Using exact many-e…
Length Scales and Power Laws in the Two-Dimensional Forest-Fire Model
A. Honecker, I. Peschel
We re-examine a two-dimensional forest-fire model via Monte-Carlo simulations and show the existence of two length scales with different critical exponents associated with clusters…
Matrix-Product States for a One-Dimensional Lattice Gas with Parallel Dynamics
A. Honecker, I. Peschel
The hopping motion of classical particles on a chain coupled to reservoirs at both ends is studied for parallel dynamics with arbitrary probabilities. The stationary state is obtai…
Critical Properties of the One-Dimensional Forest-Fire Model
A. Honecker, I. Peschel
The one-dimensional forest-fire model including lightnings is studied numerically and analytically. For the tree correlation function, a new correlation length with critical expone…
