Criticality in Frustrated Quantum Antiferromagnets
Insulating antiferromagnets offer a rich playground to explore novel quantum phases of matter. Triangular lattice s=1/2 antiferromagnets are of especial interest due to their reduced dimensionality, low spin, and frustrating interactions which all conspire to disrupt magnetic order, as found experimentally in several instances. The resulting “quantum disordered” phases are expected to have nove...
متن کاملThree-Dimensional Crystallization of Vortex Strings in Frustrated Quantum Magnets.
We demonstrate that frustrated exchange interactions can produce exotic 3D crystals of vortex strings near the saturation field (H=H(sat)) of body- and face-centered cubic Mott insulators. The combination of cubic symmetry and frustration leads to a magnon spectrum of the fully polarized spin state (H>H(sat)) with degenerate minima at multiple noncoplanar Q vectors. This spectrum becomes gaples...
متن کاملQuantum Effects and Broken Symmetries in Frustrated Antiferromagnets
We investigate the interplay between frustration and zero-point quantum fluctuations in the ground state of the triangular and J1−J2 Heisenberg antiferromagnets, using finitesize spin-wave theory, exact diagonalization, and quantum Monte Carlo methods. In the triangular Heisenberg antiferromagnet, by performing a systematic size-scaling analysis, we have obtained strong evidences for a gapless ...
متن کاملسیستمهای ناکام و همبسته الکترونی
Quantum phases and fluctuations in correlated electron systems with frustration and competing interactions are reviewed. In the localized moment case the S=1/2 J1 - J2 - model on a square lattice exhibits a rich phase diagram with magnetic as well as exotic hidden order phases due to the interplay of frustration and quantum fluctuations. Their signature in magnetocaloric quantities and the hig...
متن کاملFrustration effects in antiferromagnetic molecules: the cuboctahedron
Frustration of magnetic systems which is caused by competing interactions is the driving force of several unusual phenomena such as plateaus and jumps of the magnetization curve as well as of unusual energy spectra with for instance many singlet levels below the first triplet state. The antiferromagnetic cuboctahedron can serve as a paradigmatic example of certain frustrated antiferromagnets. I...
