Critical behavior in graphene: spinodal instability at room temperature
R. Ramirez, C. P. Herrero
At a critical spinodal in-plane stress a planar crystalline graphene layer becomes mechanically unstable. We present a model of the critical behavior of the membrane area n…
Elastic properties and mechanical tension of graphene
R. Ramirez, C. P. Herrero
Room temperature simulations of graphene have been performed as a function of the mechanical tension of the layer. Finite-size effects are accurately reproduced by an acoustic disp…
Path-integral simulation of solids
Carlos P. Herrero, Rafael Ramirez
The path-integral formulation of the statistical mechanics of quantum many-body systems is described, with the purpose of introducing practicaltechniques for the simulation of soli…
Quantum path integral simulation of isotope effects in the melting temperature of ice Ih
R. Ramirez, C. P. Herrero
The isotope effect in the melting temperature of ice Ih has been studied by free energy calculations within the path integral formulation of statistical mechanics. Free energy diff…
Strong covalent bonding between two graphene layers
P. L. de Andres, R. Ramirez, J. A. Verges
We show that two graphene layers stacked directly on top of each other (AA stacking) form strong chemical bonds when the distance between planes is 0.156 nm. Simultaneously, C-C in…
