Turing instabilities on Cartesian product networks
Malbor Asllani, Daniel M. Busiello, Timoteo Carletti +2
The problem of Turing instabilities for a reaction-diffusion system defined on a complex Cartesian product networks is considered. To this end we operate in the linear regime and e…
Conformal symmetry for relativistic point particles: an addendum
Roberto Casalbuoni, Joaquim Gomis
We extend the results of our previous work on the conformal invariant description of two relativistic point particles. We consider here the most general lagrangian by using a confo…
Uniqueness and Lipschitz stability of an inverse boundary value problem for time-harmonic elastic waves
Elena Beretta, Maarten V. de Hoop, Elisa Francini +2
We consider the inverse problem of determining the Lamé parameters and the density of a three-dimensional elastic body from the local time-harmonic Dirichlet-to-Neumann map. We pro…
Re-entrant spin-flop transition in nanomagnets
Mattia Crescioli, Paolo Politi, Ruggero Vaia
Antiferromagnetic chains with an odd number of spins are known to undergo a transition from an antiparallel to a spin-flop configuration when subjected to an increasing magnetic fi…
Stable determination of polyhedral interfaces from boundary data for the Helmholtz equation
Elena Beretta, Maarten V. de Hoop, Elisa Francini +1
We study an inverse boundary value problem for the Helmholtz equation using the Dirichlet-to-Neumann map as the data. We consider piecewise constant wavespeeds on an unknown tetrah…
A one-dimensional liquid of fermions with tunable spin
Guido Pagano, Marco Mancini, Giacomo Cappellini +8
Correlations in systems with spin degree of freedom are at the heart of fundamental phenomena, ranging from magnetism to superconductivity. The effects of correlations depend stron…
