Magnon valley Hall effect in CrI3-based vdW heterostructures
R. Hidalgo-Sacoto, R. I. Gonzalez, E. E. Vogel +5
Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet CrI3 are studied. We find that bulk magnons exhibit a non-trivial topological band structure withou…
Ground-state topology of the Edwards-Anderson +/-J spin glass model
F. Roma, S. Risau-Gusman, A. J. Ramirez-Pastor +2
In the Edwards-Anderson model of spin glasses with a bimodal distribution of bonds, the degeneracy of the ground state allows one to define a structure called backbone, which can b…
The ground state energy of the Edwards-Anderson spin glass model with a parallel tempering Monte Carlo algorithm
F. Roma, S. Risau-Gusman, A. J. Ramirez-Pastor +2
We study the efficiency of parallel tempering Monte Carlo technique for calculating true ground states of the Edwards-Anderson spin glass model. Bimodal and Gaussian bond distribut…
Influence of the Ground-State Topology on the Domain-Wall Energy in the Edwards-Anderson +/- J Spin Glass Model
F. Roma, S. Risau-Gusman, A. J. Ramirez-Pastor +2
We study the phase stability of the Edwards-Anderson spin-glass model by analyzing the domain-wall energy. For the bimodal distribution of bonds, a topological analysis of the grou…
Novel order parameter to describe the critical behavior of Ising spin glass models
F. Roma, F. Nieto, A. J. Ramirez-Pastor +1
A novel order parameter for spin glasses is defined based on topological criteria and with a clear physical interpretation. is first investigated for well known magnetic sy…
Complex temperatures zeroes of partition function in spin-glass models
D. B. Saakian, E. E. Vogel
An approximate method is proposed for investigating complex-temperature properties of real-dimensional spin-glass models. The method uses the complex-temperature data of the ferrom…
