Vanishing ordered moment in the frustrated triangular lattice antiferromagnet CuNdO2 [PDF]

npj Quantum Materials
We investigate the magnetic ground state of CuNdO2, which is a delafossite with a triangular lattice of magnetic Nd3+ ions that are well separated by non-magnetic Cu spacer layers.

Static Response of Neutron Matter [PDF]

Physical Review Letters, 2016
We generalize the problem of strongly interacting neutron matter by adding a periodic external modulation. This allows us to study from first principles a neutron system that is extended and inhomogeneous, with connections to the physics of both neutron ...

Long-range magnetic order with disordered spin orientations in a high-entropy antiferromagnet [PDF]

Nature Communications
Disorder in magnetic systems typically suppresses long-range order, promoting short-range states such as spin glasses and magnetic clusters. This is particularly prominent in high-entropy materials, characterized by the random distributions of local ...

Neutron decay, dark matter and neutron stars [PDF]

EPJ Web of Conferences, 2019
Following up on a suggestion that decay to a dark matter fermion might explain the 4σ discrepancy in the neutron lifetime, we consider the implications of such a fermion on neutron star structure.

Insights on Skyrme parameters from GW170817

Physics Letters B, 2019
The binary neutron-star merger event, GW170817, has cast a new light on nuclear physics research. Using a neutron-star model that includes a crust equation of state (EoS), we calculate the properties of a 1.4 solar-mass neutron star.

Constraining effects on polymer chain relaxation in crosslinked supramolecular dual networks

Frontiers in Soft Matter, 2023
Polymer networks containing transient physical and permanent chemical cross-links exhibit unique mechanical properties due to the intrinsic reassociating ability of supramolecular functional groups.

Measuring the counterion cloud of soft microgels using SANS with contrast variation

Nature Communications, 2023
The behavior of microgels and other soft, compressible colloids depends on particle concentration in ways that are absent in their hard-particulate counterparts.

A microscopic Kondo lattice model for the heavy fermion antiferromagnet CeIn3

Nature Communications, 2023
Electrons at the border of localization generate exotic states of matter across all classes of strongly correlated electron materials and many other quantum materials with emergent functionality.

Transition between distinct hybrid skyrmion textures through their hexagonal-to-square crystal transformation in a polar magnet

Nature Communications, 2023
Magnetic skyrmions, topological vortex-like spin textures, garner significant interest due to their unique properties and potential applications in nanotechnology.
