Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…
String Phase in an Artificial Spin Ice
Xiaoyu Zhang, Ayhan Duzgun, Yuyang Lao +13
One-dimensional strings of local excitations are a fascinating feature of the physical behavior of strongly correlated topological quantum matter. Here we study strings of local ex…
Understanding Thermal Annealing of Artificial Spin Ice
Xiaoyu Zhang, Yuyang Lao, Joseph Sklenar +6
We have performed a detailed study of thermal annealing of the moment configuration in artificial spin ice. Permalloy (NiFe) artificial spin ice samples were examined…
Direct Visualization of Memory Effects in Artificial Spin Ice
Ian Gilbert, Gia-Wei Chern, Bryce Fore +4
We experimentally demonstrate that arrays of interacting nanoscale ferromagnetic islands, known as artificial spin ice, develop reproducible microstates upon cycling an applied mag…
Replica exchange molecular dynamics optimization of tensor network states for quantum many-body systems
Wenyuan Liu, Chao Wang, Yanbin Li +4
The tensor network states (TNS) methods combined with Monte Carlo (MC) techniques have been proved a powerful algorithm for simulating quantum many-body systems. However, because t…
Non-reciprocal Oersted field contribution to the current-induced frequency shift of magnetostatic surface waves
Mohammad Haidar, Matthieu Bailleul, Mikhail Kostylev +1
The influence of an electrical current on the propagation of magnetostatic surface waves is investigated in a relatively thick (40 nm) permalloy film both experimentally and theore…
