Shearing a glass and the role of pin-delay in models of interface depinning
Stefanos Papanikolaou
When a disordered solid is sheared, yielding is followed by the onset of intermittent response that is characterized by slip in local regions usually labeled shear-transformation z…
Ising nematic fluid phase of hard-core dimers on the square lattice
Stefanos Papanikolaou, Daniel Charrier, Eduardo Fradkin
We present a model of classical hard-core dimers on the square lattice that contains an Ising nematic phase in its phase diagram. We consider a model with an attractive interaction…
Universal properties of magnetization dynamics in polycrystalline ferromagnetic films
Felipe Bohn, Marcio Assolin Correa, Alexandre Da Cas Viegas +3
We investigate the scaling behavior in the statistical properties of Barkhausen noise in ferromagnetic films. We apply the statistical treatment usually employed for bulk materials…
Quasi-periodic events in crystal plasticity and the self-organized avalanche oscillator
Stefanos Papanikolaou, Dennis M. Dimiduk, Woosong Choi +4
When external stresses in a system - physical, social or virtual - are relieved through impulsive events, it is natural to focus on the attributes of these avalanches. However, dur…
Computational studies of the glass-forming ability of model bulk metallic glasses
Kai Zhang, Minglei Wang, Stefanos Papanikolaou +4
Bulk metallic glasses (BMGs) are produced by rapidly thermally quenching supercooled liquid metal alloys below the glass transition temperature at rates much faster than the critic…
