Quenched dynamics of classical isolated systems: The spherical spin model with two-body random interactions or the Neumann integrable model
(IOP Publishing, 2018-06)
We study the Hamiltonian dynamics of the spherical spin model with fully-connected two-body random interactions. In the statistical physics framework, the potential energy is of the so-called p = 2 kind, closely linked to ...
Interfacial Properties of Tetrahydrofuran and Carbon Dioxide Mixture from Computer Simulation
(2018)
We determined the interfacial properties of the tetrahydrofuran + carbon dioxide (THF + CO2) binary mixture from direct simulation of the vapor liquid interface. We consider two different models of THF based on the ...
Environment-induced sudden transition in quantum discord dynamics
(American Physical Society - APSCollege Park, 2011-09)
Nonclassical correlations play a crucial role in the development of quantum information science. The recent discovery that nonclassical correlations can be present even in separable (nonentangled) states has broadened this ...
A simple grand canonical approach to compute the vapor pressure of bulk and finite size systems
(American Institute of Physics, 2014-02)
In this article we introduce a simple grand canonical screening (GCS) approach to accurately compute vapor pressures from molecular dynamics or Monte Carlo simulations. This procedure entails a screening of chemical ...
Quantum quench dynamics of the Coulomb Luttinger model
(American Physical Society, 2013-01)
We study the nonequilibrium dynamics of the Luttinger model after suddenly turning on and off the bare Coulomb interaction between the fermions. We analyze several correlation functions such as the one particle density ...
Note on the free energy of transfer of fullerene C60 simulated by using classical potentials
(2009)
Diverse atomistic parameters of C60 have been developed and utilized to simulate fullerene solutions in biological environments. However, no thermodynamic assessment and validation of these parameters have been so far ...
Quantum Quench and Prethermalization Dynamics in a Two-Dimensional Fermi Gas with Long-Range Interactions
(American Physical Society, 2014-11)
We study the effect of suddenly turning on a long-range interaction in a spinless Fermi gas in two dimensions. The short- to intermediate-time dynamics is described using the method of bosonization of the Fermi surface. ...
Thermalization in systems with bipartite eigenmode entanglement
(IOP Publishing, 2012-07)
It is analytically shown that the asymptotic correlations following a quantum quench in exactly solvable models can sometimes look essentially thermal provided the initial coupling between the system eigenmodes induces a ...
Static and dynamic correlation lengths in supercooled polymers
(American Institute of Physics, 2019-05)
A key point to understand the glass transition is the relationship between structural and dynamic behavior experienced by a glass former when it approaches Tg. In this work, the relaxation in a simple bead-spring polymer ...
Transition amplitude, partition function and the role of physical degrees of freedom in gauge theories
(Elsevier B.V., 2018-09-01)
This work explores the quantum dynamics of the interaction between scalar (matter) and vectorial (intermediate) particles and studies their thermodynamic equilibrium in the grand-canonical ensemble. The aim of the article ...
