Wick rotations in 3D gravity: ML(H2)-spacetimes
Riccardo Benedetti, Francesco Bonsante
"Ends of hyperbolic 3-manifolds should support canonical Wick Rotations, so they realize effective interactions of their ending globally hyperbolic spacetimes of constant curvature…
Spectral projections for the twisted Laplacian
Herbert Koch, Fulvio Ricci
The twisted Laplacian in the d=2n dimensional Euclidean space has the spectrum n+2k, k a nonnegative integer. We find sharp asymptotic bounds of the norm of the projection to the e…
Cloning transformations in spin networks without external control
G. De Chiara, R. Fazio, C. Macchiavello +2
In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling betwee…
Signature of Mott-insulator transition with ultra-cold fermions in a one-dimensional optical lattice
Xia-Ji Liu, Peter D. Drummond, Hui Hu
Using the exact Bethe ansatz solution of the Hubbard model and Luttinger liquid theory, we investigate the density profiles and collective modes of one-dimensional ultra-cold fermi…
Uniqueness of limit cycles for a class of planar vector fields
Timoteo Carletti
In this paper we give sufficient conditions to ensure uniqueness of limit cycles for a class of planar vector fields. We also exhibit a class of examples with exactly one limit cyc…
The scaling equation of state of the three-dimensional O(N) universality class: N >= 4
Agostino Butti, Francesco Parisen Toldin, Andrea Pelissetto +1
We determine the critical equation of state of the three-dimensional O(N) universality class, for N=4, 5, 6, 32, 64. The N=4 is relevant for the chiral phase transition in QCD with…
