Transport Properties of Active Particles Moving on Adjustable Networks
William G. C. Oropesa, P. de Castro, Hartmut Löwen +1
Active adaptive matter has attracted considerable interest due to its rich, largely unexplained dynamics and its relevance to a wide range of synthetic and biological materials. An…
Mean-field model for a mixture of biaxial nematogens and dipolar nanoparticles
William G. C. Oropesa, Eduardo S. Nascimento, André P. Vieira
We analyze a mean-field model for mixtures involving biaxial nematogens and dipolar nanoparticles, taking into account orientational and isotropic pair interactions between nematog…
Phase behavior of a lattice-gas model for biaxial nematics
W. G. C. Oropesa, E. S. Nascimento, A. P. Vieira
We employ a lattice-gas extension of the Maier--Saupe model with discrete orientation states to study the phase behavior of a statistical model for biaxial nematogenic units in mea…
Efficient asymmetric collisional Brownian particle engines
C. E. Fernández Noa, Angel L. L. Stable, William G. C. Oropesa +2
The construction of efficient thermal engines operating at finite times constitutes a fundamental and timely topic in nonequilibrium thermodynamics. We introduce a strategy for opt…
Thermodynamics of collisional models for Brownian particles: General properties and efficiency
Angel L. L. Stable, Carlos E. F. Noa, William G. C. Oropesa +1
We introduce the idea of {\it collisional models} for Brownian particles, in which a particle is sequentially placed in contact with distinct thermal environments and external forc…
Minimal model for the magnetic phase diagram of CeTiScGe, GdFeCoSi, and related materials
William Gabriel Carreras Oropesa, Sergio Encina, Pablo Pedrazzini +5
We present a theoretical analysis of the magnetic phase diagram of CeTiScGe and GdFeCoSi as a function of the temperature and the Sc and Co concentratio…
Landau theory for magnetic and structural transitions in CeCoFeSi
William Gabriel Carreras Oropesa, Víctor F. Correa, Julián G. Sereni +2
We present a phenomenological analysis of the magnetoelastic properties of CeCoFeSi at temperatures close to the Néel transition temperature . Using a Landau…
