An electron is usually considered to have only one form of kinetic energy, but could it have more, for its spin and charge, by exciting other electrons? In one dimension (1D), the physics of interacting electrons is captured well at low energies by t

Interactions between electrons in solids are often behind exciting novel effects such as ferromagnetism, anti-ferromagnetism and superconductivity. All these phenomena break away from the single-electron picture, instead having to take into account t

We calculate magnon dispersions and damping in the Kitaev-Heisenberg model with an off-diagonal exchange $\mathrm{\ensuremath{\Gamma}}$ and isotropic third-nearest-neighbor interact ion ${J}_{3}$ on a honeycomb lattice. This model is relevant to a de

We report an experimental and theoretical study of the low-temperature specific heat $C$ and magnetic susceptibility $\ensuremath{\chi}$ of the layered anisotropic triangular-lattice spin-$1/2$ Heisenberg antiferromagnets ${\mathrm{Cs}}_{2}{\mathrm{C

Power laws in physics have until now always been associated with a scale invariance originating from the absence of a length scale. Recently, an emergent invariance even in the presence of a length scale has been predicted by the newly-developed nonl

We study the anisotropic quantum Heisenberg antiferromagnet for spin-1/2 that interpolates smoothly between the one-dimensional (1D) and the two-dimensional (2D) limits. Using the spin Hartree-Fock approach we construct a quantitative theory of heat

We construct a new mean-field theory for quantum (spin-1/2) Heisenberg antiferromagnet in one (1D) and two (2D) dimensions using a Hartree-Fock decoupling of the four-point correlation functions. We show that the solution to the self-consistency equa

We study the effect of critical pairing fluctuations on the electronic properties in the normal state of a clean superconductor in three dimensions. Using a functional renormalization group approach to take the non-Gaussian nature of critical fluctua

We construct a many-body theory of magneto-elasticity in one dimension and show that the dynamical correlation functions of the quantum magnet, connecting the spins with phonons, involve all energy scales. Accounting for all magnetic states non-pertu
