Hopping in the crowd to unveil network topology
Malbor Asllani, Timoteo Carletti, Francesca Di Patti +2
We introduce a nonlinear operator to model diffusion on a complex undirected network under crowded conditions. We show that the asymptotic distribution of diffusing agents is a non…
Non-Fermi liquid at the FFLO quantum critical point
Dimitri Pimenov, Ipsita Mandal, Francesco Piazza +1
When a 2D superconductor is subjected to a strong in-plane magnetic field, Zeeman polarization of the Fermi surface can give rise to inhomogeneous FFLO order with a spatially modul…
The Hopfield-Kerr model and analogue black hole radiation in dielectrics
F. Belgiorno, S. L. Cacciatori, F. Dalla Piazza +1
In the context of the interaction between the electromagnetic field and a dielectric dispersive lossless medium, we present a non-linear version of the relativistically covariant H…
Point-particle method to compute diffusion-limited cellular uptake
A. Sozza, F. Piazza, M. Cencini +2
We present an efficient point-particle approach to simulate reaction-diffusion processes of spherical absorbing particles in the diffusion-limited regime, as simple models of cellu…
Exciton transport in the PE545 complex: insight from atomistic QM/MM-based quantum master equations and elastic network models
Sima Pouyandeh, Stefano Iubini, Sandro Jurinovich +3
In this paper we work out a parameterization of the environment noise within the Haken-Strobl-Reinenker (HSR) model for the PE545 light-harvesting complex based on atomic-level qua…
Disorder-Driven Density and Spin Self-Ordering of a Bose-Einstein Condensate in a Cavity
Farokh Mivehvar, Francesco Piazza, Helmut Ritsch
We study spatial spin and density self-ordering of a two-component Bose-Einstein condensate via collective Raman scattering into a linear cavity mode. The onset of the Dicke superr…
