The literature of low‐dimensional CuII molecular magnetic systems in which superexchange
pathways involve halide ions and/or cyclic 1, 4‐diazines is reviewed. Compounds are …

Two new gapless quantum spin-liquid candidates with S= 1 (Ni 2+) moments: the 6 HB
phase of Ba 3 NiSb 2 O 9 with a Ni 2+-triangular lattice and the 3C phase with a Ni 2/3 Sb …

Dimensionality plays an essential role in determining the nature and properties of a physical
system. This is particularly evident in quantum systems, where interactions and fluctuations …

We investigate weakly coupled spin-1/2 ladders in a magnetic field. The work is motivated
by recent experiments on the compound (C 5 H 12 N) 2 CuBr 4 (BPCB). We use a …

How many states of a configuration space contribute to a wave function? Attempts to answer
this ubiquitous question have a long history in physics and are keys to understanding, eg …

Nuclear magnetic resonance in high magnetic field: Application to condensed matter physics
Page 1 CR Physique 18 (2017) 331–348 Contents lists available at ScienceDirect Comptes …

Dimensionality plays an essential role in determining the nature and properties of a physical
system. For quantum systems the impact of interactions and fluctuations is enhanced in …

We review recent theoretical and experimental efforts aimed at the investigation of the
physics of interacting disordered bosons (so-called dirty bosons) in the context of quantum …

One-dimensional free fermions and hard-core bosons are often considered to be equivalent.
Indeed, when restricted to nearest-neighbor hopping on a chain, the particles cannot …

Inelastic neutron scattering is used to measure the spin excitation spectrum of the
Heisenberg S= 1/2 ladder material (C 7 H 10 N) 2 CuBr 4 in its entirety, both in the gapped …
