Theory of the magnetoeletric effect in a lightly doped high-Tc cuprate
S. Mukherjee, B. M. Andersen, Z. Viskadourakis +2
In a recent study Viskadourakis et al. discovered that extremely underdoped La_2CuO_(4+x) is a relaxor ferroelectric and a magnetoelectric material at low temperatures. It is furth…
Low-temperature ferroelectric phase and magnetoelectric coupling in the underdoped La_2CuO_(4+x)
Z. Viskadourakis, I. Radulov, A. P. Petrović +9
We report the discovery of a ferroelectric ground state below 4.5 K in highly underdoped La_2CuO_(4+x) accompanied by slow charge dynamics which develop below T~40 K. An anisotropi…
Two routes to magnetic order by disorder in underdoped cuprates
R. B. Christensen, P. J. Hirschfeld, B. M. Andersen
We study disorder-induced magnetism within the Gutzwiller approximation applied to the t-J model relevant for cuprate superconductors. In particular, we show how disorder generates…
Pinning of stripes by local structural distortions in cuprate high-Tc superconductors
U. Tricoli, B. M. Andersen
We study the spin-density wave (stripe) instability in lattices with mixed low-temperature orthorhombic (LTO) and low-temperature tetragonal (LTT) crystal symmetry. Within an expli…
Measuring spin correlations in optical lattices using superlattice potentials
K. G. L. Pedersen, B. M. Andersen, G. M. Bruun +2
We suggest two experimental methods for probing both short- and long-range spin correlations of atoms in optical lattices using superlattice potentials. The first method involves a…
