Charge Density Wave Formation in the Low-Temperature-Tetragonal Phase of Cuprates
N. Hasselmann, A. H. Castro Neto, C. Morais Smith
We calculate the influence of transverse fluctuations on the longitudinal dynamics in the striped phase of cuprates by using the bosonization technique. We find that a charge densi…
Charge Stripe in an Antiferromagnet: 1d Band of Composite Excitations
A. L. Chernyshev, Steven R. White, A. H. Castro Neto
With the help of analytical and numerical studies of the - model we argue that the charge stripe in an antiferromagnetic insulator should be understood as a system of holon…
Effect of impurities on quasi-2D quantum antiferromagnet
A. L. Chernyshev, Y. C. Chen, A. H. Castro Neto
We have studied the static and dynamic properties of quasi-two-dimensional quantum antiferromagnets (AF) diluted with spinless impurities using spin-wave theory and -matrix appr…
The Kondo Screening Cloud
Ian Affleck
Renormalization group theory of the Kondo effect predicts that an impurity spin is screened by a conduction electron spread over a large distance of order >.1 to 1 micron. This rev…
Electron Spin Resonance in S=1/2 antiferromagnetic chains
Masaki Oshikawa, Ian Affleck
A systematic field-theory approach to Electron Spin Resonance (ESR) in the quantum antiferromagnetic chain at low temperature (compared to the exchange coupling ) is…
Diluted quantum antiferromagnets: spin excitations and long-range order
A. L. Chernyshev, Y. C. Chen, A. H. Castro Neto
We have studied the static and dynamic magnetic properties of two-dimensional (2D) and quasi-two-dimensional, spin-S, quantum Heisenberg antiferromagnets (QHAF) diluted with spinle…
P-wave pairing and ferromagnetism in the metal-insulator transition in two dimensions
Claudio Chamon, Eduardo R. Mucciolo, Antonio H. Castro Neto
Based on recent experimental evidence for a spin polarized ground state in the insulating phase of the two-dimensional electron system, we propose that ferromagnetic spin fluctuati…
Droplets in Disordered Metallic Quantum Critical Systems
Antonio H. Castro Neto, Barbara A. Jones
We present a field theory for a structurally disordered magnetic system coupled to a metallic environment near a quantum critical point. We show that close to the magnetic quantum…
Geometric frustration and magnetization plateaus in quantum spin and Bose-Hubbard models on tubes
Dmitry Green, Claudio Chamon
We study XXZ Heisenberg models on frustrated triangular lattices wrapped around a cylinder. In addition to having interesting magnetic phases, these models are equivalent to Bose-H…
Phase diagram of the anisotropic Kondo chain
E. Novais, E. Miranda, A. H. Castro Neto +1
We establish the phase diagram of the one-dimensional anisotropic Kondo lattice model at T=0 using a generalized two-dimensional classical Coulomb gas description. We analyze the p…
Bond-order-wave phase and quantum phase transitions in the one-dimensional extended Hubbard model
Pinaki Sengupta, Anders W. Sandvik, David K. Campbell
We use a stochastic series expansion quantum Monte Carlo method to study the phase diagram of the one-dimensional extended Hubbard model at half filling for small to intermediate v…
