A New Type of Quantum Criticality in the Pyrochlore Iridates accepted by PRX
In this work, we exhibit an entirely new type of antiferromagnetic fermionic quantum critical point relevant to real materials, namely to the pyrochlore iridates family. Despite its three-dimensional character, this quantum critical point is highly unconventional and is accompanied by a myriad of unusual properties, such as emergent enhanced anisotropy and a crucial role for Coulomb interactions, thanks to the novel theoretical structure of the field theory that describes the vicinity of the critical point.

Signatures of the Helical Phase in the Critical Fields at Twin Boundaries of Noncentrosymmetric Superconductors published by Phys. Rev. B
In this paper, we analyze the effect of twin-boundaries on the critical fields, both lower and upper, of noncentrosymmetric superconductors. We find that these effects provide precious signatures of the helical phase in those materials. See on the Noncentrosymmetric Superconductivity Project page »

Spin Liquid Regimes at Nonzero Temperature in Quantum Spin Ice published in PRB and accompanied by a movie
In this paper we extend the analysis developed in our earlier paper to nonzero temperature, and show the corresponding full 3D phase diagram. We find that a Thermal Spin Liquid regime with properties akin to the classical spin ice regime supplants the QSL and U(1) Coulomb Ferromagnet phases at relatively low temperatures. This constitutes a relatively rare example of study of the evolution of a quantum spin liquid at nonzero temperature. See on the Pyrochlore Project page »

Definitive Evidence for Order-by-Quantum-Disorder in Er2Ti2O7 published by PRL
Our paper, which proves order-by-disorder in Er2Ti2O7, was published online by PRL today. We are now looking forward to experimental measurements of the spin wave gap (due to order-by-disorder) and comparison to the value we predict, Δ ≅ 0.02 meV = 260 mK! See on the Er2Ti2O7 Project page »

Definitive Evidence for Order-by-Quantum-Disorder in Er2Ti2O7 now on arXiv
In this paper, we exhibit for the first time definitive evidence of order-by-disorder in a real material, namely Er2Ti2O7. The proof of order-by-disorder resides within the robustness of the classical degeneracy. Order-by-disorder driven by quantum fluctuations is shown to describe all accessible experimental features. Several other predictions, in particular the existence of a measurable gap are described, and many comparisons with experiments are made. The manuscript with details of this work is now available on arXiv. See on the Research & publications page »

Coulombic Quantum Liquids in Spin-1/2 Pyrochlores now on arXiv
In this paper, we give a nonperturbative study of spin-1/2 magnets on the pyrochlore lattice using a novel slave-particle approach and a "gauge Mean Field Theory". We show that the phase diagram contains two exotic (Coulombic) phases, the well-known U(1) Quantum Spin Liquid, which contains photon and monopole excitations, and a new phase of matter, the U(1) Coulomb Ferromagnet, which we characterize. The manuscript with details of this work is now available on arXiv. See on the Research & publications page »

Quantum Excitations in Quantum Spin Ice is now published in PRX, with a "Viewpoint" in Physics by Rajiv Singh
We have been working on Yb2Ti2O7, a rare-earth pyrochlore material with the (experimental) group of Bruce Gaulin. We demonstrated that this material was a quantum version of spin ice and was likely to exhibit U(1) quantum spin liquid behavior in low field and at low temperature. The manuscript with details of this work is now published in PRX, and is accompanied by a Viewpoint in Physics by R. Singh. See on the Research & publications page »
