Quantum Simulator with Electrons Floating on a Helium Film — •sarah Mostame1 and Ralf Schuetzhold2 — 1MPI-PKS, Dresden, Germany — 2Fachbereich Physik, Universitaet Duisburg-Essen, Duisburg, Germany
We propose a physical setup that can be used to simulate the quantum dynamics of the Ising model in a transverse field. Building on currently available technology, our scheme consists of electrons which float on a superfluid helium film covering a suitable substrate and interact via Coulomb forces. At low temperatures, the system will stay near its ground state where its Hamiltonian is equivalent to the Ising model and thus shows phenomena such as quantum criticality.
