The fundamental problem of treating light incoherence in photovoltaics and its practical consequences

open access: yesNew Journal of Physics, 2014
The incoherence of sunlight has long been suspected to have an impact on solar cell energy conversion efficiency, although the extent of this is unclear.

Testing electron–phonon coupling for the superconductivity in kagome metal CsV3Sb5

open access: yesNature Communications, 2023
Electron-phonon coupling is thought to be too weak to be responsible for the superconducting Cooper pairing of the kagome metals AV3Sb5, but an experimental measurement is lacking.

Dielectric anomalies and interactions in the three-dimensional quadratic band touching Luttinger semimetal Pr2Ir2O7

open access: yesNature Communications, 2017
The electronic structure of Pr2Ir2O7 contains a quadratic band touching, which is expected to lead to unusual interaction-driven behavior. Here, the authors use spectroscopic measurements to observe signatures of strong interactions but also that Fermi ...

Elastic Models for the Non-Arrhenius Relaxation Time of Glass-Forming Liquids [PDF]

open access: yes, 2006
We first review the phenomenology of viscous liquids and the standard models used for explaining the non-Arrhenius average relaxation time. Then the focus is turned to the so-called elastic models, arguing that these models are all equivalent in the ...

Quantum-Matter Heterostructures

open access: yes, 2016
Combining the power and possibilities of heterostructure engineering with the collective and emergent properties of quantum materials, quantum-matter heterostructures open a new arena of solid-state physics.

Voltage Signals Caused by Surface Acoustic Wave Driven Ferromagnetic Resonance Under Out‐of‐Plane External Fields

open access: yesAdvanced Materials Interfaces, 2022
Under an external magnetic field, surface acoustic waves (SAWs) propagating onto a ferromagnetic thin film can excite ferromagnetic resonance (FMR). The magnetization precessional motion in resonance pumps spin current into the Rashba interface across an

Index theorem on chiral Landau bands for topological fermions

open access: yes, 2021
Topological fermions as excitations from multi-degenerate Fermi points have been attracting increasing interests in condensed matter physics. They are characterized by topological charges, and magnetic fields are usually applied in experiments for their ...

Parafermionization, bosonization, and critical parafermionic theories

open access: yesJournal of High Energy Physics, 2021
We formulate a ℤ k -parafermionization/bosonization scheme for one-dimensional lattice models and field theories on a torus, starting from a generalized Jordan-Wigner transformation on a lattice, which extends the Majorana-Ising duality at k = 2. The ℤ k
