Phase diagram of the XXZ pyrochlore model from pseudo-Majorana functional renormalization group
Yannik Schaden, Matías G. Gonzalez, Johannes Reuther
We calculate the magnetic phase diagram of the spin- nearest neighbor XXZ pyrochlore model using the pseudo-Majorana functional renormalization group in the temperature flow f…
Field-induced spin liquid in the decorated square-kagome antiferromagnet nabokoite KCuTeO(SO)Cl
Matías G. Gonzalez, Yasir Iqbal, Johannes Reuther +1
Quantum antiferromagnets based on the square-kagome lattice are proving to be a fertile platform for realizing nontrivial phenomena in frustrated magnetism. Recently, several decor…
Magnetic properties of the spiral spin liquid and surrounding phases in the square lattice XY model
Matías G. Gonzalez, Anna Fancelli, Han Yan +1
Spiral spin liquids possess a subextensively degenerate ground-state manifold, represented by a continuum of energy minima in reciprocal space. Since a small change of the spiral s…
Temperature flow in pseudo-Majorana functional renormalization for quantum spins
Benedikt Schneider, Johannes Reuther, Matías G. Gonzalez +2
We implement the temperature flow scheme first proposed by Honerkamp and Salmhofer in Phys.~Rev.~B 64, 184516 (2001) into the pseudo-Majorana functional renormalization group metho…
Dynamics of KNi(SO) governed by proximity to a 3D spin liquid model
M. G. Gonzalez, V. Noculak, A. Sharma +9
Quantum spin liquids (QSLs) have become a key area of research in magnetism due to their remarkable properties, such as long-range entanglement, fractional excitations, pinch-point…
Finite-temperature phase transitions in three-dimensional Heisenberg magnets from high-temperature series expansions
M. G. Gonzalez, B. Bernu, L. Pierre +1
Many frustrated spin models on three-dimensional (3D) lattices are currently being investigated, both experimentally and theoretically, and develop new types of long-range orders i…
Partially disordered Heisenberg antiferromagnet with short-range stripe correlations
G. G. Blesio, F. T. Lisandrini, M. G. Gonzalez
Zero-point quantum fluctuations of a Néel order can produce effective interactions between quasi-orphan spins weakly coupled to the lattice. On the distort…
Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids
A. O. Scheie, Y. Kamiya, Hao Zhang +20
Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
Ground-state and thermodynamic properties of the spin- Heisenberg model on the anisotropic triangular lattice
Matías G. Gonzalez, Bernard Bernu, Laurent Pierre +1
The spin- triangular lattice antiferromagnetic Heisenberg model has been for a long time the prototypical model of magnetic frustration. However, only very recently this m…

M. G. Gonzalez, B. Bernu, L. Pierre +1
We present an interpolation method for the specific heat , when there is a phase transition with a logarithmic singularity in at a critical temperature . The m…

We study the infinite-U Hubbard model on ladders of 2, 4 and 6 legs with nearest (t) and next-nearest (t') neighbor hoppings by means of the density-matrix renormalization group al…
Correlated partial disorder in a weakly frustrated quantum antiferromagnet
M. G. Gonzalez, F. T. Lisandrini, G. G. Blesio +3
Partial disorder --the microscopic coexistence of long-range magnetic order and disorder-- is a rare phenomenon, that has been experimental and theoretically reported in some Ising…
