Carbon Nanostructures as an Electromechanical Bicontinuum
Cristiano Nisoli, Paul E. Lammert, Eric Mockensturm +1
A two-field model provides an unifying framework for elasticity, lattice dynamics and electromechanical coupling in graphene and carbon nanotubes, describes optical phonons, nontri…
Demagnetization Protocols for Frustrated Interacting Nanomagnet Arrays
R. F. Wang, J. Li, W. McConville +8
We report a study of demagnetization protocols for frustrated arrays of interacting single domain permalloy nanomagnets by rotating the arrays in a changing magnetic field. The mos…
Static and Dynamical Phyllotaxis in a Magnetic Cactus
Cristiano Nisoli, Nathaniel Gabor, Paul E. Lammert +1
While the statics of many simple physical systems reproduce the striking number-theoretical patterns found in the phyllotaxis of living beings, their dynamics reveal unusual excita…
Ground state lost but degeneracy found: the effective thermodynamics of artificial spin ice
Cristiano Nisoli, R. F. Wang, Jie Li +4
We analyze the rotational demagnetization of artificial spin ice, a recently realized array of nanoscale single-domain ferromagnetic islands. Demagnetization does not anneal this m…
