Ice Rule Fragility via Topological Charge Transfer in Artificial Colloidal Ice
Andras Libal, Don Yun Lee, Antonio Ortiz-Ambriz +4
Artificial particle ices are model systems of constrained, interacting particles. They have been introduced theoretically to study ice-manifolds emergent from frustration, along wi…
The Inner Phases of Colloidal Hexagonal Ice
A. Libal, C. Nisoli, C. J. O. Reichhardt +1
Using numerical simulations that mimic recent experiments on hexagonal colloidal ice, we show that colloidal hexagonal artificial spin ice exhibits an inner phase within its ice st…
Dynamical Stationarity as a Result of Sustained Random Growth
Tamás Biró, Zoltán Néda
In sustained growth with random dynamics stationary distributions can exist without detailed balance. This suggests thermodynamical behavior in fast growing complex systems. In ord…
Dynamic Control of Topological Defects in Artificial Colloidal Ice
A. Libal, C. Nisoli, C. Reichhardt +1
We demonstrate the use of an external field to stabilize and control defect lines connecting topological monopoles in spin ice. For definiteness we perform Brownian dynamics simula…
Equilibrium distributions in entropy driven balanced processes
Tamás S. Biró, Zoltán Néda
For entropy driven balanced processes we obtain final states with Poisson, Bernoulli, negative binomial and Pólya distributions. We apply this both for complex networks and particl…
Hysteresis and Return Point Memory in Artificial Spin Ice Systems
A. Libal, C. Reichhardt, C. J. Olson Reichhardt
We investigate hysteresis loops and return point memory for artificial square and kagome spin ice systems by cycling an applied bias force and comparing microscopic effective spin…
