Model for a quantum Hall effect without Landau levels: Condensed-matter realization of the "parity anomaly"

open access: yesPhysical Review Letters, 1988
A two-dimensional condensed-matter lattice model is presented which exhibits a nonzero quantization of the Hall conductance ${\ensuremath{\sigma}}^{\mathrm{xy}}$ in the absence of an external magnetic field.

Learning the electronic density of states in condensed matter [PDF]

open access: yes, 2020
The electronic density of states (DOS) quantifies the distribution of the energy levels that can be occupied by electrons in a quasiparticle picture, and is central to modern electronic structure theory.

Attosecond spectroscopy in condensed matter

open access: yesNature, 2007
Comprehensive knowledge of the dynamic behaviour of electrons in condensed-matter systems is pertinent to the development of many modern technologies, such as semiconductor and molecular electronics, optoelectronics, information processing and photovoltaics.

Nanoscale inhomogeneity and the evolution of correlation strength in FeSe $$_{1-x}$$ 1 - x S $$_x$$ x

open access: yesNano Convergence, 2023
We report a comprehensive study of the nanoscale inhomogeneity and disorder on the thermoelectric properties of FeSe $$_{1-x}$$ 1 - x S $$_x$$ x ( $$0 \le x \le 1$$ 0 ≤ x ≤ 1 ) single crystals and the evolution of correlation strength with S substitution.

Magnetic properties of the Larkin-Ovchinnikov-Fulde-Ferrell superconducting phase [PDF]

open access: yes, 2004
We compute, at the first order in the fine structure constant, the parameters of the electromagnetic Lagrangian for the inhomogeneous Larkin-Ovchinnikov-Fulde-Ferrell phase in Quantum Chromodynamics (QCD) and in condensed matter. In particular we compute

Exciton diffusion in two-dimensional metal-halide perovskites

open access: yesNature Communications, 2020
The so-called two-dimensional (2D) layered perovskites possess distinct optoelectronic properties from their 3D counterparts due to their reduced dimensionality. Here Seitz et al. investigate the exciton transport dynamics in 2D perovskites and highlight

Modulation of optical absorption in m-Fe1−xRuxS2 and exploring stability in new m-RuS2

open access: yesScientific Reports, 2021
A first-principle computational method has been used to investigate the effects of Ru dopants on the electronic and optical absorption properties of marcasite FeS2.

Condensate dark matter stars [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2012
We investigate the structure and stability properties of compact astrophysical objects that may be formed from the Bose-Einstein condensation of dark matter. Once the critical temperature of a boson gas is less than the critical temperature, a Bose-Einstein Condensation process can always take place during the cosmic history of the universe.

Atomistic insights into highly active reconstructed edges of monolayer 2H-WSe2 photocatalyst

open access: yesNature Communications, 2022
Systematically study of in-plane intrinsic defects and edge atoms is important to guide the design of low-dimensional photocatalysts. Here the authors investigate photocatalytic CO2 reduction to CH4 over reconstructed edge atoms of monolayer ...

Effect of adhesive interaction on strain stiffening and dissipation in granular gels undergoing yielding

open access: yesCommunications Physics, 2022
Non-linearity and energy dissipation in athermal disordered solids undergoing strain-induced yielding and fluidization remain poorly understood. Here, the authors use oscillatory shear rheology, in-situ imaging, and particle settling experiments to study
