Dynamic phase transition in a rotating external field

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

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 superposition of any two ground states of the Ising chain. In particular, one can end up with the Ising chain in a superp...

A Novel Transformer-Based Single-to-Three Phase Conversion Technique Using Rotating Magnetic Field Theory

This paper presents a new single to three phase converter using rotating magnetic field transformer. Conventional transformers have been used in many converters aiming at supplementary improvements and they usually have no critical effect on the conversion technique. In this paper, the conversion technique is based on a special rotating magnetic field transformer in which there are two windings...

On the External Field Effect in the Landau Theory of the Weakly-first-order Phase Transition

The effect of the external field on the weakly-discontinuous first-order phase transition is analyzed in the frame of the Landau theory. The transformation of the free energy expansion as a power series in the order parameter is suggested that maps the first-order phase transition onto the second-order one under the ’effective’ external field, that depends on both temperature and on real field ...

Phase transition induced by a magnetic field

The magnetic catalysis of discrete chiral symmetry breaking in the 2+1 dimensional Nambu-Jona-Lasinio model is analyzed. A particular attention is paid to a possible application of the effect in solid state physics. The fermion contribution to the thermal conductivity as a function of the dynamical mass (energy gap in the spectrum) is estimated and is shown to be suppressed when a non-zero orde...
