Critical phenomena and quantum phase transition in long range Heisenberg antiferromagnetic chains
Nicolas Laflorencie, Ian Affleck, Mona Berciu
Antiferromagnetic Hamiltonians with short-range, non-frustrating interactions are well-known to exhibit long range magnetic order in dimensions, but exhibit only quasi lo…
Kondo screening in a magnetically frustrated nanostructure: Exact results on a stable, non-Fermi-liquid phase
Kevin Ingersent, Andreas W. W. Ludwig, Ian Affleck
Triangular symmetry stabilizes a novel non-Fermi-liquid phase in the three-impurity Kondo model with frustrating antiferromagnetic interactions between half-integer impurity spins.…
Frustration of Decoherence in Open Quantum Systems
E. Novais, A. H. Castro Neto, L. Borda +2
We study a model of frustration of decoherence in an open quantum system. Contrary to other dissipative ohmic impurity models, such as the Kondo model or the dissipative two-level…
Quantum vs. Classical Magnetization Plateaus of S=1/2 Frustrated Heisenberg Chains
Kazuo Hida, Ian Affleck
The competition between quantum and classical magnetization plateaus of S=1/2 frustrated Heisenberg chains with modified exchange couplings is investigated. The conventional S=1/2…
