Degenerate ground-state lattices of membrane inclusions.

Particles that are embedded in fluid membranes or plates can induce bending if they impose a nonzero angle of contact. This bending mediates complicated effective particle-particle interactions. In the absence of tension, these interactions are nonpairwise additive and can result in clusters of particles with specific configurations that give rise to zero total membrane bending energy. Here, we...

A Potts model with infinitely degenerate ground state

A q-component Potts model with ferromagnetic and antiferromagnetic interactions in the two respective directions of a square lattice is considered. An argument is given showing that an ordered phase can exist in this model, even though the ground state is disordered and infinitely degenerate. We use the Migdal-Kadanoff transformation to obtain a closed-form expression for its critical point. We...

The ground state phases of orbitally degenerate spinel oxides

I review the microscopic spin-orbital Hamiltonian and ground state properties of spin one-half spinel oxides with threefold t2g orbital degeneracy. It is shown that for any orbital configuration a ground state of corresponding spin only Hamiltonian is infinitely degenerate in the classical limit. The extensive classical degeneracy is lifted by the quantum nature of the spins, an effect similar ...

Disorder-induced neutral solitons in degenerate ground state polymers

We study the effects of weak off-diagonal disorder on π-conjugated polymers with a doubly degenerate ground-state. We find that disorder induces a finite density of neutral solitons in the lattice dimerization of a polymer chain. Interchain interactions result in a linear potential between the solitons and, if sufficiently strong, bind them into pairs resulting in an exponential suppression of ...

Reentrant orbital order and the true ground state of LaSr2Mn2O7.

Contrary to conventional wisdom, our purified La 2-2x Sr 1+2x Mn2O7 crystals exhibit CE-type orbital and charge order as the low-temperature ground state for a hole doping level h=0.5. For small deviations from h=0.5, the high-temperature CE phase is replaced at low temperatures by an A-type antiferromagnet without coexistence. Larger deviations result in a lack of CE order at any temperature. ...
