Mechanisms for Spin-Supersolidity in S=1/2 Spin-Dimer Antiferromagnets
J. -D. Picon, A. F. Albuquerque, K. P. Schmidt +3
Using perturbative expansions and the contractor renormalization (CORE) algorithm, we obtain effective hard-core bosonic Hamiltonians describing the low-energy physics of s…
Kondo screening cloud and the charge staircase in one-dimensional mesoscopic devices
Rodrigo G. Pereira, Nicolas Laflorencie, Ian Affleck +1
We propose that the finite size of the Kondo screening cloud, xi_K, can be probed by measuring the charge quantization in a one-dimensional system coupled to a small quantum dot. W…
Thermodynamics of impurities in the anisotropic Heisenberg spin-1/2 chain
J. Sirker, S. Fujimoto, N. Laflorencie +2
The thermodynamics of finite open antiferromagnetic XXZ chains is studied using field theory, Bethe Ansatz and quantum Monte Carlo methods. For the susceptibility a parameter-free…
Kondo Effect in Spin Chains
Nicolas Laflorencie, Erik S. Sørensen, Ian Affleck
The free electron Kondo problem can be described by a one-dimensional (1D) model because only the s-wave part of the electronic wave-function is affected by the Kondo coupling. Sin…
Correlation amplitude and entanglement entropy in random spin chains
J. A. Hoyos, André P. Vieira, Nicolas Laflorencie +1
Using strong-disorder renormalization group, numerical exact diagonalization, and quantum Monte Carlo methods, we revisit the random antiferromagnetic XXZ spin-1/2 chain focusing o…
Quantum and thermal transitions out of the supersolid phase of a 2D quantum antiferromagnet
Nicolas Laflorencie, Frederic Mila
We investigate the thermodynamic properties of a field-induced supersolid phase in a 2D quantum antiferromagnet model. Using quantum Monte Carlo simulations, a very rich phase diag…
