Diverted negative triangularity plasmas on DIII-D: the benefit of high confinement without the liability of an edge pedestal

Stefano Coda, Alessandro Marinoni, Francesco Sciortino

Diverted discharges at negative triangularity on the DIII-D tokamak sustain normalized confinement and pressure levels typical of standard H-mode scenarios (H (98y2) similar or equal to 1, beta (N) similar or equal to 3) without developing an edge pressure ...

A Variable Structure Control Scheme Proposal for the Tokamak a Configuration Variable

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Timothy Goodman, Jonathan Graves, Yves Martin, Jean-Marc Moret, Ivo Furno, Duccio Testa

Fusion power is the most significant prospects in the long-term future of energy in the sense that it composes a potentially clean, cheap, and unlimited power source that would substitute the widespread traditional nonrenewable energies, reducing the geogr ...

Sliding Surface Based Schemes for the Tokamak a Configuration Variable

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Timothy Goodman, Jonathan Graves, Yves Martin, Jean-Marc Moret, Stefano Alberti, Ivo Furno

Fusion power may be seen as the energy of the future in the sense that it composes a potentially clean, cheap and unlimited power source that would reduce the worldwide dependency on non-renewable energies. Nevertheless, while nowadays the fusion reaction ...

On the possibility of extending the Noro-Frenkel generalized law of correspondent states to nonisotropic patchy interactions

Giuseppe Foffi, Francesco Sciortino

Colloidal systems (and protein solutions) are often characterized by attractive interactions whose ranges are much smaller than the particle size. When this is the case and the interaction is spherical, systems obey a generalized law of correspondent state ...

Extended law of corresponding states in short-range square wells: A potential energy landscape study

Giuseppe Foffi, Francesco Sciortino

We study the statistical properties of the potential energy landscape of a system of particles interacting via a very short-range square-well potential (of depth - u0) as a function of the range of attraction Δ to provide thermodynamic insights of the Noro ...

Arrested phase separation in a short-ranged attractive colloidal system: A numerical study

Giuseppe Foffi, Francesco Sciortino

We numerically investigate the competition between phase separation and dynamical arrest in a colloidal system interacting via a short-ranged attractive potential. Equilibrium fluid configurations are quenched at two different temperatures below the critic ...

Diffusivity and configurational entropy maxima in short range attractive colloids

Giuseppe Foffi, Francesco Sciortino

We study tagged particle diffusion at large packing fractions, for a model of particles interacting with a generalized Lennard-Jones 2n-n potential, with large n. The resulting short range potential mimics interactions in colloidal systems. In agreement wi ...

Scaling of dynamics with the range of interaction in short-range attractive colloids

Giuseppe Foffi, Francesco Sciortino

We numerically study the dependence of the dynamics on the range of interaction Δ for the short-range square well potential. We find that, for small Δ, dynamics scale exactly in the same way as thermodynamics, both for Newtonian and Brownian microscopic dy ...
