Urban Gravity: a Model for Intercity Telecommunication Flows (2009)
Krings, G., Calabrese, F., Ratti, C., Blondel, V. D.
We analyze the anonymous communication patterns of 2.5 million customers of a Belgian mobile phone operator. Grouping customers by billing address, we build a social network of cities, that consists...

A PNJL model in 0+1 Dimensions (2008)
Dusling, K., Ratti, C., Zahed, I.
We formulate the Polyakov-Nambu-Jona-Lasinio (PNJL) model in 0+1 dimensions. The thermodynamics captured by the partition function yields a bulk pressure, as well as quark susceptibilities versus...
Dennis Frenchman City Design and Development Group, DUSP (2008)
John P Wilson, A Stewart Fotheringham, Gary J Hunter, Carlo Ratti, Yao Wang, Hiroshi Ishii, ...
In recent years, an increasing amount of effort has gone into the design of GIS user interfaces. On the one hand, Graphical User Interfaces (GUIs) with a high degree of sophistication have replaced...
Real and imaginary-time $Q\bar{Q}$ correlators in a thermal medium (2007)
We investigate the behavior of a pair of heavy fermions, denoted by $Q$ and $\bar{Q}$, in a hot/dense medium. Although we have in mind the situation where $Q$ and $\bar{Q}$ denote heavy quarks, our...
Thermodynamics of the PNJL model (2006)
Ratti, C., Roessner, S., Thaler, M. A., Weise, W.
QCD thermodynamics is investigated by means of the Polyakov-loop-extended Nambu Jona-Lasinio (PNJL) model, in which quarks couple simultaneously to the chiral condensate and to a background temporal...
Hansen, H., Alberico, W. M., Beraudo, A., Molinari, A., Nardi, M., Ratti, C.
We investigate the properties of scalar and pseudo-scalar mesons at finite temperature and quark chemical potential in the framework of the Nambu-Jona-Lasinio (NJL) model coupled to the Polyakov loop...
Phases of QCD: lattice thermodynamics and a field theoretical model (2005)
Ratti, C., Thaler, M. A., Weise, W.
We investigate three-colour QCD thermodynamics at finite quark chemical potential. Lattice QCD results are compared with a generalized Nambu Jona-Lasinio model in which quarks couple simultaneously...
Thermodynamics of two-colour QCD and the Nambu Jona-Lasinio model (2004)
We investigate two-flavour and two-colour QCD at finite temperature and chemical potential in comparison with a corresponding Nambu and Jona-Lasinio model. By minimizing the thermodynamic potential...
Raster analysis of urban form (2004)
A new paradigm for investigating the environmental consequences of urban texture is proposed. Using raster-based models and software algorithms derived from image processing the authors develop...
The NJL model and strange quark matter (2002)
The stability of strange quark matter is studied within the Nambu Jona-Lasinio model with three different parameter sets. The model Lagrangian contains 4-fermion (with and without vector interaction)...
Stability of strange quark matter: model dependence (2002)
The minimum energy per baryon number of strange quark matter is studied, as a function of the strangeness fraction, in the MIT bag model and in two different versions of the Color Dielectric Model: a...
Baryonic masses based on the NJL model (2002)
Alberico, W. M., Giacosa, F., Nardi, M., Ratti, C.
We employ the Nambu Jona--Lasinio model to determine the vacuum pressure on the quarks in a baryon and hence their density inside. Then we estimate the baryonic masses by implementing the local...
Stability of strange quark matter in the MIT bag model and in the Color Dielectric Model (2001)
We utilize the MIT bag model and two different versions of the Color Dielectric Model in order to study the properties of strange matter, and to discuss the stability of strangelets. We also...
Stability of strange quark matter: MIT bag versus Color Dielectric Model (2001)
Alberico, W. M., Drago, A., Ratti, C.
We discuss the properties of strange matter, in particular the minimum of the energy per baryon number as a function of the strangeness fraction. We utilize both the MIT bag model and the Color...
Urban texture analysis with image processing techniques (1999)
A new paradigm for investigating the environmental consequences of urban texture is proposed. Using raster-based models and software algorithms derived from image processing, efficient methods of...
