Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable...

On the basis of exchange couplings obtained from early inelastic neutron measurements, we conjecture that the stacked honeycomb magnet FeTiO3 contains Dirac nodal lines in the...

Ca10Cr7O28 is a quantum spin liquid ������ characterised by the absence of static magnetic order where the spins are in coherent dynamical motion in the ground state. This state...

The excitations of an Ising antiferromagnetic chain have been studied in the past and are known to form either continuous spectrum or Zeeman ladders. Such a system can be...

A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic"...

New electronic phases often emerge in the proximity of a quantum critical point (QCP) - that is the point where the transition temperature of a collective phase transition is...

The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model uniquely provides exactly...

We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial...

In the proposed experiment we intend to resolve the spin waves in GdPtBi, which is an outstanding representative of a novel class of magnets - topological antiferromagnets. In...

Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed...

A large amount of contemporary research by both chemists and physicists is focused on exploiting the spin of electrons with the attempt of revolutionising the current technology...

We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition...

We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it...

Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood...

We plan to study the temperature dependence of magnetic excitations in the optimally doped high-Tc superconductor Bi$2$Sr$_2$CaCu$_2$O${8+\delta}$ (BSCCO). We have previously...

The debate whether interband or intraband scattering is crucial for Fe-based superconductors is not settled down yet. Investigation a system with completely missing electron...

We propose to study the magnetic fluctuations of the unconventional superconductor Sr2RuO4 in the superconducting state extending our previous experiments on a cold triple-axis...

Sr2RuO4 is a 2-D layered perovskite oxide metal which becomes superconducting below 1.5K. There is strong experimental evidence that the superconducting wavefunction is...

ZnCr2Se4 is a magnetically frustrated spinel compound with an incommensurate helical ground state. It has a pyrochloremagnetic sublattice which is formed by Cr3+ (S = 3/2)...

The proposed research aims to probe the effects of alkyl chain length on the dynamics of a room temperature ionic liquid (RTIL) in bulk and in confinement in nano porous carbon...
