Interpretations of Quantum Theory in the Light of Modern Cosmology
Mario Castagnino, Sebastian Fortin, Roberto Laura +1
The difficult issues related to the interpretation of quantum mechanics and, in particular, the "measurement problem" are revisited using as motivation the process of generation of…
Physical properties as modal operators in the topos approach to quantum mechanics
Hector Freytes, Graciela Domenech, Christian de Ronde
In the framework of the topos approach to quantum mechanics we give a representation of physical properties in terms of modal operators on Heyting algebras. It allows us to introdu…
Rippling, buckling and melting of single- and multi-layer MoS
Sandeep Kumar Singh, M. Neek-Amal, S. Costamagna +1
Large-scale atomistic simulations using the reactive empirical bond order force field approach is implemented to investigate thermal and mechanical properties of single-layer (SL)…
Theory of anharmonic phonons in 2D crystals
K. H. Michel, S. Costamagna, F. M. Peeters
Anharmonic effects in an atomic monolayer thin crystal with honeycomb lattice structure are investigated by analytical and numerical lattice dynamical methods. Starting from a semi…
Pseudogap in cuprates driven by d-wave flux-phase order proximity effects: A theoretical analysis from Raman and ARPES experiments
Andres Greco, Matias Bejas
One of the puzzling characteristics of the pseudogap phase of high- cuprates is the nodal-antinodal dichotomy. While the nodal quasiparticles have a Fermi liquid behaviour, th…
Phase Transitions and Antiferroelectrivity in BiFeO3 from Atomic Level Simulations
M. Graf, M. Sepliarsky, S. Tinte +1
The structural and polar properties of BiFeO3 at finite temperature are investigated using an atomistic shell model fitted to first-principles calculations. Molecular Dynamics simu…
