Finite size Berezinski-Kosterlitz-Thouless transition at grain boundaries in solid He and role of He impurities
S. Gaudio, E. Cappelluti, G. Rastelli +1
We analyze the complex phenomenology of the Non-Classical Rotational Inertia (NCRI) observed at low temperature in solid He within the context of a two dimensional Berezinski-K…
Surface instability and isotopic impurities in quantum solids
E. Cappelluti, G. Rastelli, S. Gaudio +1
In this paper we employ a self-consistent harmonic approximation to investigate surface melting and local melting close to quantum impurities in quantum solids. We show that surfac…
Optical and spectral properties of quantum domain-walls in the generalized Wigner lattice
S. Fratini, G. Rastelli
We study the spectral properties of a system of electrons interacting through long-range Coulomb potential on a one-dimensional chain. When the interactions dominate over the elect…
Wigner crystallization in a polarizable medium
G. Rastelli, S. Ciuchi
We present a variational study of the 2D and 3D Wigner crystal phase of large polarons. The method generalizes that introduced by S. Fratini,P.\ Qu{é}merais [Mod. Phys. Lett. B {\b…
