Non-naturally reductive Einstein metrics on normal homogeneous Einstein manifolds [PDF]

open access: yesarXiv, 2017
It is an important problem in differential geometry to find non-naturally reductive homogeneous Einstein metrics on homogeneous manifolds. In this paper, we consider this problem for some coset spaces of compact simple Lie groups. A new method to construct invariant non-naturally reductive Einstein metrics on normal homogeneous Einstein manifolds is ...

Realizing Intrinsically Ultralow and Glass‐Like Thermal Transport via Chemical Bonding Engineering

open access: yesAdvanced Science, EarlyView.
Lattice thermal conductivity can be effectively suppressed by introducing a S2 − anion into the bridging position between the Ag–Ag bond in the Ag6 octahedron, which weakens the Ag–Ag bond within the octahedral structure and enhances phonon‐phonon scattering rates. Abstract Crystals exhibiting glass‐like and low lattice thermal conductivity (κL$\kappa_{

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities

open access: yesAdvanced Science, EarlyView.
This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal

Broad Poly(pentacenetetrone) as a High‐capacity Cathode for Sodium Batteries

open access: yesAdvanced Science, EarlyView.
Poly(pentacenetetrone) (PPT) is introduced as a high‐capacity cathode for sodium batteries, offering 314 mAh g⁻¹ at 0.2C with excellent cycling stability. At 2C, it retains 92% capacity after 500 cycles. PPT's high performance and stability address key challenges in sodium battery technology, making it a promising material for next‐generation energy ...

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.
