Quantum limits in the measurement of very small displacements in optical images
Claude Fabre, J. -B. Fouet, Agnès Maître
We consider the problem of the measurement of very small displacements in the transverse plane of an optical image with a split photodetector. We show that the standard quantum lim…
Ising phases of Heisenberg ladders in a magnetic field
Karlo Penc, Jean-Baptiste Fouet, Shin Miyahara +2
We examine the influence of weak anisotropic interactions on the T=0 phase diagram of the frustrated two-leg Heisenberg ladder, a well-studied spin model exhibiting integer and fra…
Uniform and staggered magnetizations induced by Dzyaloshinskii-Moriya interactions in isolated and coupled spin 1/2 dimers in a magnetic field
S. Miyahara, J. -B. Fouet, S. R. Manmana +5
We investigate the interplay of Dzyaloshinskii-Moriya interactions and an external field in spin 1/2 dimers. For isolated dimers and at low field, we derive simple expressions for…
Field Induced Staggered Magnetization and Magnetic Ordering in
M. Clemancey, H. Mayaffre, C. Berthier +6
We present a D NMR investigation of the gapped spin-1/2 compound . Our measurements reveal the presence of a magnetic field induced transverse sta…
Condensation of magnons and spinons in a frustrated ladder
J. -B. Fouet, F. Mila, D. Clarke +4
Motivated by the ever-increasing experimental effort devoted to the properties of frustrated quantum magnets in a magnetic field, we present a careful and detailed theoretical anal…
Frustrated three-leg spin tubes: from spin 1/2 with chirality to spin 3/2
J. -B. Fouet, A. Laeuchli, S. Pilgram +2
Motivated by the recent discovery of the spin tube [(CuCltachH)Cl]Cl, we investigate the properties of a frustrated three-leg spin tube with antiferromagnetic intra-rin…
