Hillslopes in the Canadian High Arctic can express curious quasi-linear sorted stripe patterns, physically resembling rills but with no obvious evidence of active particle transport via sustained surface water flows following rainfall or snowmelt. This motivates several questions which at present are little explored. First, how do the physical characteristics of the pattern vary down the...

Biochar, a carbon-rich solid produced through the pyrolysis of biomass feedstocks, has demonstrated potential as a sustainable concrete additive. In addition to its sustainability benefits, biochar presents physical benefits in concrete as an inert filler material with a porous structure, high specific surface area (SSA), and surface functional groups: the result has demonstrated improvements...

The Kibble mechanism plays a prominent role in the theory of the early Universe, as an explanation of the possible formation of cosmic strings. Zurek suggested the analogous effect in liquid helium under rapid cooling, and he conjectured, together with del Campo and Kibble, a scaling-law for the relation between the density of remnant topological defects and the cooling rate, when a system...

We study electronic Raman scattering (eRS) from low-energy excitations in many-electron metallic systems lacking inversion symmetry. In these systems, spin–orbit coupling lifts spin degeneracy at the Fermi level, enabling incoherent spin-flip excitations and coherent chiral-spin modes, which can be probed via Raman spectroscopy. These excitations have been experimentally observed using...

The rigorous Equation of State of any material under external isotropic pressure $P$
$ \hspace{2.5cm} P =\frac {1}{\beta} \frac {\partial \ln Z}{\partial V}, $
based on the system partition function $Z$, is taught in almost every related textbook.
The Equation of State of crystals under general external stress $\mathbf{S}$ was derived:

Biosensing using graphene field-effect transistors (GFETs) is an emerging research area in which device reliability and performance critically depend on the functionalization of the graphene surface. Non-covalent grafting of molecular receptors via π–π stacking is widely employed to induce chemical specificity while preserving graphene’s electronic properties. However, the microscopic...

It is often accepted that the Zak phase of one-dimensional topological insulators corresponds to the number of edge states. However, the Zak phase fails to predict edge states in some cases, and when it does its prediction depends on the choice of unit cell. We provide a derivation of bulk-boundary correspondence that successfully predicts the number of edge states in semi-infinite chains,...

A recent study in the context of elemental lithium and sodium has brought out a remarkable property of close-packed solids (CPSs). Under certain assumptions, the electronic band structure is identical for any CPS. This leads to a large degeneracy, with an infinite number of structural configurations for the ground state. Here, structural frustration is explored further in the context of...

Periodically driven quantum spin chains provide a framework to study chaotic dynamics. We investigate this in the Floquet 1D transverse-field Ising model (Floquet TFIM) via numerical simulations, emphasizing space-time light-cone structure and wavefront interference, motivated by fronts noted in the quenched (non-kicked) TFIM. We introduce a periodic transverse-field kick to define a Floquet...

The Canadian Neutron Beam Laboratory (CNBL) is a new core research facility based at the McMaster Nuclear Reactor, a 5 MW open-pool reactor located at McMaster University in Hamilton, Ontario. The CNBL is currently the only facility in the country which provides access to neutron scattering capabilities, offering unique opportunities for the experimental characterization of quantum materials,...

Phytoglycogen (PG) is a glucose-based polysaccharide produced in the form of compact, monodisperse, electrically neutral nanoparticles in sweet corn kernels. Its highly branched, dendritic architecture leads to interesting and useful properties that make PG ideal as a unique additive in personal care, nutrition, and biomedical formulations. To tailor PG to specific applications, we can modify...

Triangular graphene quantum dots (TGQD) with zig-zag edges are synthetic structures in which the presence of a zero-energy shell at the Fermi level generates electronic correlations and entanglement. We present here the result of Hubbard model calculations in TGQD and show the spin-polarized energy spectrum for spin up and down. We also calculate the density matrix elements for bilayer bulk...

The family of A2BB’O6 5d1 double perovskite materials has recently attracted attention due to their potential for multipolar ordering and the interplay of spin, orbital, lattice, and electronic degrees of freedom. In particular, the A2MgReO6 (A= Ba, Sr, Ca) family has recently been demonstrated to have a spin-orbit-lattice entangled ground state [1], prompting deeper exploration of the...

Single-walled carbon nanotubes (SWCNTs) are one-dimensional nanomaterials with exceptional electrical, thermal, mechanical, and optical properties. Despite their great potential in diverse nanotechnology applications, as-synthesized SWCNTs are inherently bundled because of strong vdW interactions. Consequently, their highly regarded properties are greatly compromised. Many applications of...
