Unveiling the exotic quantum critical point in CeCu6-xAgx
The heavy fermion system CeCu6-xAux is arguably the most important (and studied) heavy fermion series which exhibits a quantum critical point. In recent years several new... -
Spin dynamics in the extended Kagome system YBaCo4O(7+x)
A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which... -
Tunable algebraic correlations and Kasteleyn transition in kagome ice
We propose to continue our search for the Kasteleyn transition in the kagome ice phase of the spin ice Ho2Ti2O7. The experiment requires the applied magnetic field to be... -
Tuning confinement potential of spinons in an Ising chain using magnetic fields
The Ising chain realises the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two kinks (spinons) that can separate away at no energy cost,... -
Investigation of a frustrated quantum magnet with novel interaction scheme
SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of... -
Quantum Criticality in YFe2Al10
Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10... -
In-situ hydrogen decomposition studies of ammonia borane and the diammoniate ...
Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3... -
What is the cause for the gapped mode in the `BEC' phase of DTN?
Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an... -
Exotic spin excitations in a quasi one-dimensional anisotropic Heisenberg magnet
Very recently, string states have been identified for the first time in antiferromagnetic Heisenberg-Ising chain SrCo2V2O8 in longitudinal magnetic fields using high-resolution...
