The authors study the phenomena of many-body localization in a random field Heisenberg chain. In this paper the authors use a shift-inverse exact diagonalization approach that allows them to study the mid-spectrum spectral properties of the model for system sizes of up to N=22. This has allow the authors to identify the many-body localization edge.
Phase diagram of the antiferromagnetic XXZ model on the triangular lattice

This paper studies studies the spin-1/2 XXZ antiferromagnet on a triangular lattice using a density matrix renormalization group. The authors study the phase diagram of this model as a function of magnetic field and spin anisotropy.

In type-II multiferroics ferroelectricity is driven by magnetism, and the coupling between the two orders is generally larger than in conventional multiferroic materials. However, a critical problem that needs to be overcome for type-II multiferroics is that their polarization is far too low to be useful for applications. In this Rapid Communication, a group of researchers from Osaka University, Japan, demonstrate that in three prototypical manganites (TbMnO, DyMnO, and GdMnO) magnetic field can induce giant changes in polarization under high pressure. In the gadolinium compound, the change they have observed reaches the record high value of 1.3 C/cm among the spin-driven multiferroics.
