Pinwheel-shaped bound triplet pairs in the magnetization plateaus of SrCu(BO)
Igor Vinograd, Philippe Corboz, Steffen Krämer +5
The sequence of magnetization plateaus at 1/8, 2/15, 1/6, 1/4, 1/3, 2/5, and 1/2 of the saturation observed in SrCu(BO) remained a puzzle until tensor-networks-based nu…
Topological Triplons in the Pinwheel Valence Bond Solid on the Kagome Lattice
Laura Calonge-Martínez, Peng Rao, Frédéric Mila +1
We investigate the triplon excitations of the pinwheel valence-bond-solid phase on the deformed kagome lattice compound Rb2Cu3SnF12. Using bond-operator mean-field theory, we compu…
Quantum spin liquid phase in the Shastry-Sutherland model revealed by high-precision infinite projected entangled-pair states
Philippe Corboz, Yining Zhang, Boris Ponsioen +1
The Shastry-Sutherland model is an effective model of the layered material SrCu(BO), which exhibits an extremely rich phase diagram as a function of pressure and magnet…
Degeneracy and ordering of the non-coplanar phase of the classical bilinear-biquadratic Heisenberg model on the triangular lattice
S. E. Korshunov, F. Mila, K. Penc
We investigate the zero-temperature behavior of the classical Heisenberg model on the triangular lattice in which the competition between exchange interactions of different orders…
The emergence of Resonating Valence Bond physics in spin-orbital models
F. Mila, F. Vernay, A. Ralko +3
We discuss how orbital degeneracy, which is usually removed by a cooperative Jahn-Teller distortion, could under appropriate circumstances lead rather to a Resonating Valence Bond…
Ferromagnetism in multi--band Hubbard models: From weak to strong Coulomb repulsion
Karlo Penc, Hiroyuki Shiba, Frédéric Mila +1
We propose a new mechanism which can lead to ferromagnetism in Hubbard models containing triangles with different on-site energies. It is based on an effective Hamiltonian that we…
Shadow band in the one-dimensional large Hubbard model
Karlo Penc, Karen Hallberg, Frederic Mila +1
We show that the factorized wave-function of Ogata and Shiba can be used to calculate the dependent spectral functions of the one-dimensional, infinite Hubbard model, and o…
Susceptibility of the one-dimensional, dimerized Hubbard model
Frederic Mila, Karlo Penc
We show that the zero temperature susceptibility of the one-dimensional, dimerized Hubbard model at quarter-filling can be accurately determined on the basis of exact diagonalizati…
Spectral function of the 1D Hubbard model in the limit
Karlo Penc, Frédéric Mila, Hiroyuki Shiba
We show that the one-particle spectral functions of the one-dimensional Hubbard model diverge at the Fermi energy like in the limit. The…
Charge gap in the one--dimensional dimerized Hubbard model at quarter-filling
K. Penc, F. Mila
We propose a quantitative estimate of the charge gap that opens in the one-dimensional dimerized Hubbard model at quarter-filling due to dimerization, which makes the system effect…
Exact result on the Mott transition in a two-dimensional model of strongly correlated electrons
Frederic Mila
We study the properties of a quarter-filled system of electrons on a square lattice interacting through a local repulsion and a nearest-neighbour repulsion in the limit $V=…
