Dynamic conductivity of one-dimensional ion conductors. Impedance, Nyquist diagrams
I. V. Stasyuk, R. Ya. Stetsiv
Dynamic conductivity of the one-dimensional ion conductor is investigated at different values of the interaction constant between particles and the modulating field. The considerat…
Quantum phase transitions: The mean-field perspective
Johannes Richter, Oleg Derzhko
To illustrate a simple mean-field-like approach for examining quantum phase transitions we consider the quantum Heisenberg antiferromagnet on a square lattice. The exc…
Theoretical description of pump/probe experiments in electron mediated charge-density-wave insulators
J. K. Freericks, O. Matveev, Wen Shen +2
In this review, we develop the formalism employed to describe charge-density-wave insulators in pump/probe experiments using ultra short driving pulses of light. The theory emphasi…
Resonant enhancement of thermoelectric properties by correlated hopping for the Falicov-Kimball model on Bethe lattice
D. A. Dobushovskyi, A. M. Shvaika, V. Zlatić
The effect of correlated hopping on the charge and heat transport of strongly correlated particles is studied for the Falicov-Kimball model on the Bethe lattice. Exact solutions fo…
Time-domain pumping a quantum-critical charge-density-wave-ordered material
O. P. Matveev, A. M. Shvaika, T. P. Devereaux +1
We determine the exact time-resolved photoemission spectroscopy for a nesting driven charge-density-wave (described by the spinless Falicov-Kimball model within dynamical mean-fiel…
Spin- and angle-resolved photoemission on the topological Kondo Insulator candidate: SmB6
N. Xu, H. Ding, M. Shi
Topological Kondo insulators are a new class of topological insulators in which metallic surface states protected by topological invariants reside in the bulk band gap at low tempe…
Fractional magnetization plateaux of the spin-1/2 Heisenberg orthogonal-dimer chain revisited: strong-coupling approach developed from the exactly solved Ising-Heisenberg model
Taras Verkholyak, Jozef Strecka
The spin-1/2 Heisenberg orthogonal-dimer chain is considered within the perturbative strong-coupling approach, which is developed from the exactly solved spin-1/2 Ising-Heisenberg…
Directly characterizing the relative strength and momentum dependence of electron-phonon coupling using resonant inelastic x-ray scattering
T. P. Devereaux, A. M. Shvaika, K. Wu +9
The coupling between lattice and charge degrees of freedom in condensed matter materials is ubiquitous and can often result in interesting properties and ordered phases, including…
Hubbard models with nearly flat bands: Ground-state ferromagnetism driven by kinetic energy
Patrick Müller, Johannes Richter, Oleg Derzhko
We consider the standard repulsive Hubbard model with a flat lowest-energy band for two one-dimensional lattices (diamond chain and ladder) as well as for a two-dimensional lattice…
