Nematic quantum phases in the bilayer honeycomb antiferromagnet
H. Zhang, C. A. Lamas, M. Arlego +1
The spin Heisenberg antiferromagnet on the honeycomb bilayer lattice is shown to display a rich variety of semiclassical and genuinely quantum phases, controlled by the inter…
Magnetization process in a frustrated plaquette dimerized ladder
F. Elias, M. Arlego, C. A. Lamas
The magnetic phase diagram of a plaquette dimerized antiferromagnetic system is studied by using a combination of numerical and analytical techniques. For the strongly frustrated r…
Quantum phases in the frustrated Heisenberg model on the bilayer honeycomb lattice
Hao Zhang, M. Arlego, C. A. Lamas
We use a combination of analytical and numerical techniques to study the phase diagram of the frustrated Heisenberg model on the bilayer honeycomb lattice. Using the Schwinger boso…
Quantum phases of a frustrated four-leg spin tube
M. Arlego, W. Brenig, Y. Rahnavard +3
We study the ground state phase diagram of a frustrated spin-1/2 four-leg tube. Using a variety of complementary techniques, namely density matrix renormalization group, exact diag…
Anisotropic frustrated Heisenberg model on the honeycomb lattice
A. Kalz, M. Arlego, D. Cabra +2
We investigate the ground-state phase diagram of an anisotropic Heisenberg model on the honeycomb lattice with competing interactions. We use quantum Monte Carlo simulations, as we…
Resonances in a dilute gas of magnons and metamagnetism of isotropic frustrated ferromagnetic spin chains
M. Arlego, F. Heidrich-Meisner, A. Honecker +2
We show that spin-S chains with SU(2)-symmetric, ferromagnetic nearest-neighbor and frustrating antiferromagnetic next-nearest-neighbor exchange interactions exhibit metamagnetic b…
Quasi-periodic spin chains in a magnetic field
M. Arlego, D. C. Cabra, M. D. Grynberg
We study the interplay between a (quasi) periodic coupling array and an external magnetic field in a spin-1/2 XXZ chain. A new class of magnetization plateaux are obtained by means…
