Roughness density
Nirvana Caballero, Thierry Giamarchi
The theory of disordered elastic systems is one of the most powerful frameworks to assess the physics of multiple systems that span from ferromagnets to migrating biological cells.…
Phase separation on surfaces in presence of matter exchange
Nirvana Caballero, Karsten Kruse, Thierry Giamarchi
We present a field theory to describe the composition of a surface spontaneously exchanging matter with its bulk environment. By only assuming matter conservation in the system, we…
Dynamic response and roughening of ferroelectric domain walls driven at planar electrode edges
Guillaume Rapin, Sophia Ehrensperger, Cédric Blaser +2
Understanding and controlling the motion, stability, and equilibrium configuration of ferroelectric domain walls is key for their integration into potential nanoelectronics applica…
Microscopic interplay of temperature and disorder of a one-dimensional elastic interface
Nirvana Caballero, Thierry Giamarchi, Vivien Lecomte +1
Elastic interfaces display scale-invariant geometrical fluctuations at sufficiently large lengthscales. Their asymptotic static roughness then follows a power-law behavior, whose a…
Degradation of domains with sequential field application
Nirvana Caballero
Recent experiments show striking unexpected features when alternating square magnetic field pulses are applied to ferromagnetic samples: domains show area reduction and domains wal…
From bulk descriptions to emergent interfaces: connecting the Ginzburg-Landau and elastic line models
Nirvana Caballero, Elisabeth Agoritsas, Vivien Lecomte +1
Controlling interfaces is highly relevant from a technological point of view. However, their rich and complex behavior makes them very difficult to describe theoretically, and henc…
Tuning Ginzburg-Landau theory to quantitatively study thin ferromagnetic materials
Pamela C. Guruciaga, Nirvana Caballero, Vincent Jeudy +2
Along with experiments, numerical simulations are key to gaining insight into the underlying mechanisms governing domain wall motion in thin ferromagnetic systems. However, a direc…
Magnetic domain wall creep and depinning: a scalar field model approach
Nirvana B. Caballero, Ezequiel E. Ferrero, Alejandro B. Kolton +3
Magnetic domain wall motion is at the heart of new magneto-electronic technologies and hence the need for a deeper understanding of domain wall dynamics in magnetic systems. In thi…
Dynamic heterogeneity in an orientational glass
Nirvana B. Caballero, Mariano Zuriaga, Josep Lluis Tamarit +1
Family of compounds CBrCl has been proven helpful in unraveling microscopic mechanisms responsible of glassy behavior. Some of the family members show translational ord…
Excess velocity of magnetic domain walls close to the depinning field
Nirvana B. Caballero, Iván Fernández Aguirre, Lucas J. Albornoz +8
Magnetic field driven domain wall velocities in [Co/Ni] based multilayers thin films have been measured using polar magneto-optic Kerr effect microscopy. The low field results are…
Dynamic Heterogeneity In The Monoclinic Phase Of CCl
Nirvana B. Caballero, Mariano Zuriaga, Marcelo Carignano +1
Carbon tetrachloride (CCl) is one of the simplest compounds having a translationally stable monoclinic phase while exhibiting a rich rotational dynamics below 226 K. Recent nuc…
Molecular kinetics of solid and liquid CHCl
Nirvana B. Caballero, Mariano Zuriaga, Marcelo A. Carignano +1
We present a detailed analysis of the molecular kinetics of CHCl in a range of temperatures covering the solid and liquid phases. Using nuclear quadrupolar resonance we determi…
The Plastic and Liquid Phases of CClBr Studied by Molecular Dynamics Simulations
Nirvana Caballero, Mariano Zuriaga, Marcelo Carignano +1
We present a molecular dynamics study of the liquid and plastic crystalline phases of CClBr. We investigated the short-range orientational order using a recently developed clas…
