The quasi-2D Mott insulator Ca2RuO4 has a metal-to-insulator transition (MIT) controllable through temperature, pressure, epitaxial strain, and curiously -- electrical current. However, the mechanism by which the current induces the MIT has yet to be understood. We use angle-resolved photoemisson spectroscopy (ARPES) with nanometer scale resolution to compare the electronic band structures in...

spin ice material has many interesting properties such as geometrical frustration, non-zero magnetic moment and magnetic monopoles, the spin ice especially the quantum spin ice material was an active research areas. When temperature is low enough, the quantum fluctuation in spin ice material can lead to a liquid like material known as quantum spin liquid. In this paper, we use group theory to...

It is an increasingly urgent to protect the environment from the different kinds of pollutants, in particular industrial pollutants. Wastewater treatment is one example of these efforts that are necessary for mankind to enjoy a sustainable future. Recently, the use of piezoelectric nanomaterials as catalyst for water purification has been reported. It has been demonstrated that the...

In recent years, physicists have discovered that the topological electronic structure of materials can have dramatic consequences on their properties. In a new variety of topological materials called Weyl semimetals, electrons behave as massless relativistic particles. These materials are in some sense a 3-dimensional equivalent to graphene. Many interesting magneto-electric effects, that...

Recent advances in experiment and theory suggest that superfluid $^3$He under planar confinement may form a pair-density wave (PDW) whereby superfluid and crystalline orders coexist. While a natural candidate for this phase is a unidirectional stripe phase predicted by Vorontsov and Sauls in 2007, recent nuclear magnetic resonance measurements of the superfluid order parameter rather suggest a...

The Quantum Spin Liquid is a novel magnetic ground state, characterized by quantum entanglement without long range magnetic order. Kagome lattice Heisenberg antiferromagnet is a prime candidate of quantum spin liquid owing to highly frustrated spin ½’s arranged on a corner sharing triangle geometry. We report 19F NMR investigation of a series of “barlowite” kagome material...

HEOs have garnered much attention as candidates for high-efficiency batteries
and heat shields [2, 3]. HEOs composed of four and five binary oxides have
been previously investigated by infrared [4] and Raman spectroscopy [5] and

Neutron scattering is an invaluable tool for studying the bulk characteristics of condensed matter systems. With the shutdown of the National Research Universal (NRU) reactor at Chalk River in 2018, Canada lost its main source of neutrons for spectroscopy and diffraction experiments, forcing those working at Canadian institutions to look abroad. There is currently a national effort to rebuild...
