Tuneable skyrmion and anti-skyrmion fluids via mechanical strain in chiral kagome lattice
Gonzalo dos Santos, Flavia A. Gómez Albarracín, Ludovic D. C. Jaubert +3
Magnetic skyrmions are nanometric swirling spin textures that exhibit remarkable stability at finite temperatures, making them promising candidates for spintronic applications. Ach…
Interplay of electric and magnetic fields in skyrmion phases of the classical Heisenberg model on a square lattice
A. Vela Wac, F. A. Gómez Albarracín, D. C. Cabra
Magnetic skyrmions, topologically stable spin textures, have attracted significant interest due to their potential applications in information storage and processing. They are typi…
Chromatographic Peak Shape from Stochastic Model: Analytic Time-Domain Expression in Terms of Physical Parameters and Conditions under which Heterogeneity Reduces Tailing
Hernán R. Sánchez
A time-domain representation of chromatographic peak shapes is presented as an analytic expression designed for high computational efficiency, which can be used for direct time-dom…
Inheritance Entropy: A Model-Independent Method to Probe the Hereditary Structure of Cell Lineage Trees
Alessandro Allegrezza, Riccardo Beschi, Domenico Caudo +14
Human bone marrow stromal cells (BMSC) include skeletal stem cells with ground-breaking therapeutic potential. However, BMSC colonies have very heterogeneous in vivo behaviour, due…
Forced silo discharge: Simulation and theory
Luis. A. Pugnaloni, Marcos A. Madrid, J. R. Darias
We study, through discrete element simulations, the discharge of granular materials through a circular orifice on the base of a cylindrical silo forced by a surcharge. At the begin…
Frustration-driven topological textures on the honeycomb lattice: antiferromagnetic meron-antimeron and skyrmion crystals emerging from spiral spin liquids
M. Mohylna, F. A. Gómez Albarracín, M. Žukovič +1
Skyrmions -- topologically nontrivial magnetic quasi-particles -- can emerge in two-dimensional chiral magnets due to moderate or high strength of the Dzyaloshinskii-Moriya (DM) in…
Pinch-line spin liquids as layered Coulomb phases and applications to cubic models
Naïmo Davier, Flavia A. Gómez Albarracín, H. Diego Rosales +2
Spin liquids form fluctuating magnetic textures which have to obey certain rules imposed by frustration. These rules can often be written in the form of a Gauss law, indicating the…
Quantum Fluctuations in the van der Walls material
Paula Mellado, Mauricio Sturla
We present the magnetic excitation spectrum of the quantum magnet near the zig-zag ground state of a minimal honeycomb spin Hamiltonian that includes bilinear and biqu…
Probing Random-Bond Disorder Effects on Ferromagnetic Skyrmion Arrays
E. Iroulart, F. A. Gómez Albarracín, H. Diego Rosales
In this work, we examined the impact of disorder in a ferromagnetic skyrmion lattice by introducing random-bond disorder based on two different models for both exchange and Dzyalos…
Perfectly hidden order and Z2 confinement transition in a fully packed monopole liquid
Attila Szabo, Santiago A. Grigera, P. C. W. Holdsworth +5
We investigate a variant of spin ice whose degenerate ground states are densely packed monopole configurations. An applied field drives this model through a Z2 confinement transiti…
Out of equilibrium response and fluctuation-dissipation violations across scales in flocking systems
Federica Ferretti, Irene Giardina, Tomas Grigera +2
Flocking systems are known to be strongly out of equilibrium. Energy input occurs at the individual level to ensure self-propulsion, and the individual motility in turn contributes…
Discrete Laplacian thermostat for flocks and swarms: the fully conserved Inertial Spin Model
Andrea Cavagna, Javier Cristín, Irene Giardina +2
Experiments on bird flocks and midge swarms reveal that these natural systems are well described by an active theory in which conservation laws play a crucial role. By building a s…
The Inertial Spin Model of flocking with position-dependent forces
Sebastián Carruitero, Alejo Costa Duran, Giulia Pisegna +2
We propose an extension to the ISM of flocking and swarming. The model has been introduced to explain certain dynamic features of swarming (second sound, a lower than expected dyna…
From chiral spin liquids to skyrmion fluids and crystals, and their interplay with itinerant electrons
F. A. Gómez Albarracín, H. D. Rosales, Masafumi Udagawa +2
The physics of skyrmions, and in particular the issue of how to isolate and manipulate them individually, is a subject of major importance nowadays in the community of magnetism. I…
Intruder in a two-dimensional granular system: statics and dynamics of force networks in an experimental system experiencing stick-slip dynamics
R. Basak, R. Kozlowski, L. A. Pugnaloni +4
In quasi-two-dimensional experiments with photoelastic particles confined to an annular region, an intruder constrained to move in a circular path halfway between the annular walls…
Magnetic ground state and perturbations of the distorted kagome Ising metal TmAgGe
C. B. Larsen, D. G. Mazzone, N. Gauthier +7
We present the magnetic orders and excitations of the distorted kagome intermetallic magnet TmAgGe. Using neutron single crystal diffraction we identify the propagation vectors $\b…
Combined approach to analyze and classify families of classical spin liquids
Naïmo Davier, Flavia A. Gómez Albarracín, H. Diego Rosales +1
Classical spin liquids have been a very active subject of research in the last few years. A very rich variety of cases have been shown to exist, including short-range and algebraic…
Repulsion driven metallic phase in the ground state of the half-filled ionic Hubbard chain
Gerardo L. Rossini, George I. Japaridze
An unusual metallic phase is proven to develop in the one dimensional ionic Hubbard model, at half-filling and zero magnetization, at intermediate electron-electron repulsion w…
Dynamical fractal and anomalous noise in a clean magnetic crystal
Jonathan N. Hallén, Santiago A. Grigera, D. Alan Tennant +2
Fractals -- objects with non-integer dimensions -- occur in manifold settings and length scales in nature, ranging from snowflakes and lightning strikes to natural coastlines. Much…

M. Mohylna, F. A. Gómez Albarracín, M. Žukovič +1
Magnetic skyrmions are topological quasiparticles of great interest for data storage applications because of their small size, high stability, and ease of manipulation via electric…
Tricritical behavior in a neural model with excitatory and inhibitory units
Joaquin Almeira, Tomas S. Grigera, Dante R. Chialvo +1
While the support for the relevance of critical dynamics to brain function is increasing, there is much less agreement on the exact nature of the advocated critical point. Thus, a…
