Measurements of the longitudinal elastic constants c11, c22 and c33 and the ultrasonic attenuation α of the quasi-two-dimensional triangular-lattice spin-1/2 Heisenberg antiferromagnet Cs2CuCl4 reveal distinct anomalies near the B-induced quantum-critical point (QCP). These anomalies are particularly strongly pronounced in the ultrasonic attenuation. In isothermal field sweeps performed at low temperatures 0.027 K ≤ T ≤ 0.3 K around the saturation field Bs, the ultrasonic attenuation of all…

Ordering in Cs2CuCl4: Possibility of a proximate spin liquid
The layered spiral magnet Cs2CuCl4 displays several interesting properties that have been suggested as evidence of proximity to a two-dimensional quantum spin liquid. In this paper we study a

Interplay of quantum criticality and geometric frustration in columbite
CoNb2O6 is a material with remarkable properties that are determined by an exciting interplay of quantum mechanics and geometric frustration. On the one hand, weakly coupled ferromagnetic Ising
Dimensional reduction at a quantum critical point
TLDR
Evidence is shown that the Bose–Einstein condensate of spin triplets in the three-dimensional Mott insulator BaCuSi2O6 provides an experimentally verifiable example of dimensional reduction at a QCP.
Direct measurement of the spin Hamiltonian and observation of condensation of magnons in the 2D frustrated quantum magnet Cs2CuCl4.
TLDR
By applying strong fields, a method for measuring spin Hamiltonians is proposed and applied to the spin- 1/2 Heisenberg antiferromagnet Cs2CuCl4, which shows a 2D fractionalized resonating valence bond state at low fields.
Experimental realization of a 2D fractional quantum spin liquid.
TLDR
The dynamic correlations show a highly dispersive continuum of excited states, characteristic of the resonating valence bond state, arising from pairs of S = 1/2 spinons.
Stable phases of the Cs2CuCl4-xBrx mixed systems
Starting from Cs2CuCl4 and Cs2CuBr4, we focus on the growth of the Cs2CuCl4−xBrx mixed crystals from aqueous solution and the investigation of the occurring structural variations. The well-known
Electron - phonon effects in heavy fermion systems
A discussion of ultrasonic propagation in normal and superconducting heavy fermion systems is presented. In the normal state the temperature and magnetic field dependence of elastic constants is
Geometric frustration and dimensional reduction at a quantum critical point.
We show that the spatial dimensionality of the quantum critical point associated with Bose-Einstein condensation at T=0 is reduced when the underlying lattice comprises layers coupled by a
