A quantum phase transition in a quantum external field: Superposing two magnetic phases

Creator:

Rams, Marek M., Zwolak, Michael, and Damski, Bogdan

Abstract:

We study an Ising chain undergoing a quantum phase transition in a quantum magnetic field. Such a field can be emulated by coupling the chain to a central spin initially in a superposition state. We show that - by adiabatically driving such a system - one can prepare a quantum...
