One of us has recently found experimental evidence for unconventional superconductivity in a newly synthesized three-dimensional nearly antiferromagnetic metal, LaAg1−xMnx...

Majorana fermion, proposed by Ettore Majorana in 1937, is a putative elementary spin-1/2 particle that is its own antiparticle. In condensed-matter systems, analogs of Majorana...

The frustrated pyrochlore Er2Ti2O7 is a rare example of a magnetic system in which quantum fluctuations are capable of selecting a unique ground state out of the macroscopically...

One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may...

Among the rare earth titanates and stannates cristallising in the pyrochlore crystal structure, Tb2Ti2O7 is a singular system since its ground state is believed to be a spin...

Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest as reduced dimensionality supports strong quantum fluctuations which can result...

We will examine the impact of metal-halide hydrogen bond motifs and their ability to provide low-dimensional superexchange pathways. Specifically, we wish to investigate two new...

It is proposed to use TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions that...

Our susceptibility studies of the frustrated magnet Yb2Sn2O7 has revealed a spin glass transition of the Yb3+ magnetic lattice at T_g = 140 mK. To our knowledge, this...

The combination of strong magnetic frustration and low spin found in the S=1/2 quantum antiferromagnet is believed to lead to non-classical magnetic behaviour, and in particular...

PdxTaSe2 series is an excellent system for the investigation of the interplay between CDW and superconductivity which shows quantum critical point for x = 0.1. Very recently, we...

A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+)....

Recently, a new family of ternary platinum phosphide superconductors have been synthesised with the chemical formula APt3P (A = Sr, Ca, and La, with Tc’s of 8.4, 6.6, and 1.5 K,...

Coexistence of charge density wave (CDW) and superconductivity (SC) is a long standing puzzle in condensed matter physics. LaPt2Si2 exhibits CDW transition at 112 K followed by...

Our muSR study on Ce(Os1-xFex)2Al10 with x=0.4, which reveals long range magnetic ordering below 24K from the heat capacity, shows unexpected behaviour. The muSR spectra only...

Skyrmions are chiral magnetic spin textures that exist in a variety of different magnetic materials. Skyrmions are usually stabilized in noncentrosymmetric chiral materials by...

In recent times, Ce based HF compounds have become a promising and active research field in condensed matter physics as one can drive the system towards quantum critical point...

One dimensional Heisenberg antiferromagnetic (1DHAF) chain systems continue to attract interest as there are several outstanding questions about the nature of the propagation of...

The ability to manipulate quantum states of matter is a goal of condensed matter science. Recent progress in molecular magnetism has shown the potential for gaining control over...

Spin–orbit coupling (SOC) is a fundamental interaction in solids that can induce unusual physical properties, from topologically non-trivial insulating states to unconventional...
