Thermal conductivity of the Toda lattice with conservative noise
Alessandra Iacobucci, Frederic Legoll, Stefano Olla +1
We study the thermal conductivity of the one dimensional Toda lattice perturbed by a stochastic dynamics preserving energy and momentum. The strength of the stochastic noise is con…
Free energy calculations: An efficient adaptive biasing potential method
Bradley M. Dickson, Frederic Legoll, Tony Lelievre +2
We develop an efficient sampling and free energy calculation technique within the adaptive biasing potential (ABP) framework. By mollifying the density of states we obtain an appro…
Reducing the thermal conductivity of carbon nanotubes below the random isotope limit
Gabriel Stoltz, Natalio Mingo, Francesco Mauri
We find that introducing segmented isotopic disorder patterns may considerably reduce the thermal conductivity of pristine carbon nanotubes below the uncorrelated disorder value. T…
The many-body Green function of degenerate systems
Christian Brouder, Gianluca Panati, Gabriel Stoltz
A rigorous non perturbative adiabatic approximation of the evolution operator in the many-body physics of degenerate systems is derived. This approximation is used to solve the lon…
Gell-Mann and Low formula for degenerate unperturbed states
Christian Brouder, Gianluca Panati, Gabriel Stoltz
The Gell-Mann and Low switching allows to transform eigenstates of an unperturbed Hamiltonian into eigenstates of the modified Hamiltonian . This switching can be pe…
Constant entropy sampling and release waves of shock compressions
Jean-Bernard Maillet, Emeric Bourasseau, Laurent Soulard +2
We present several equilibrium methods that allow to compute isentropic processes, either during the compression or the release of the material. These methods are applied to comput…
