Wigner crystallization in quantum electron bilayers

, 1996
The phase diagram of quantum electron bilayers in zero magnetic field is obtained using density functional theory. For large electron densities the system is in the liquid phase, while for smaller densities the liquid may freeze (Wigner crystallization ...

Surface effects on the Mott-Hubbard transition in archetypal V$_2$O$_3$

, 2015
We present an experimental and theoretical study exploring surface effects on the evolution of the metal-insulator transition in the model Mott-Hubbard compound Cr-doped V$_2$O$_3$.

High-order Path Integral Monte Carlo methods for solving quantum dot problems [PDF]

, 2015
The conventional second-order Path Integral Monte Carlo method is plagued with the sign problem in solving many-fermion systems. This is due to the large number of anti-symmetric free fermion propagators that are needed to extract the ground state wave ...

Gli scritti sacri di Goldoni [PDF]

, 2016
Nel 1725 il giovane Goldoni viene espulso dal Collegio Ghislieri di Pavia a seguito di uno scandalo causato da un componimento satirico - il perduto Colosso - contro le giovani pavesi.

Phases in Strongly Coupled Electronic Bilayer Liquids

, 1997
The strongly correlated liquid state of a bilayer of charged particles has been studied via the HNC calculation of the two-body functions. We report the first time emergence of a series of structural phases, identified through the behavior of the two ...

INTEGRAL spectral variability study of the atoll 4U 1820-30: first detection of hard X-ray emission

, 2006
We study the 4-200 keV spectral and temporal behaviour of the low mass X-ray binary 4U 1820-30 with INTEGRAL during 2003-2005. This source as been observed in both the soft (banana) and hard (island) spectral states.

Structural Transitions in A Crystalline Bilayer : The Case of Lennard Jones and Gaussian Core Models [PDF]

, 2008
We study structural transitions in a system of interacting particles arranged as a crystalline bilayer, as a function of the density $\rho$ and the distance $d$ between the layers.

Orchestrating musical (meta)data to better address the real-world search queries of musicologists

, 2009
The dispersal of musicology’s diverse array of primary and secondary sources across countless libraries and archives was once an enormous obstacle to conducting research, but this has largely been overcome by the digitisation and online publication of ...

Exchange and correlation energy functionals for two-dimensional open-shell systems

, 2009
We consider density functionals for exchange and correlation energies in two-dimensional systems. The functionals are constructed by making use of exact constraints for the angular averages of the corresponding exchange and correlation holes ...

Variability in the orbital profiles of the X-ray emission of the gamma-ray binary LS I +61 303

, 2010
We report on the analysis of Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) monitoring observations of the $\gamma$-ray binary system LS I +61 303, covering 35 full cycles of its orbital motion.
