Ab Initio Thermoelectric Transport Calculations of Alloyed Half‐Heuslers

Advanced Science, EarlyView.
The effect of alloying on the electronic transport of half‐Heusler thermoelectric materials is explored using a fully ab initio approach. A novel method is developed that combines calculations of alloyed supercells with Boltzmann transport, considering the full energy and momentum dependent scattering processes from first principles extracted ...

Seeing the Chemistry of Biomolecular Condensates: In Situ Mapping of Composition and Water Content

Advanced Science, EarlyView.
Raman hyperspectral imaging combined with spectral phasor analysis enables a label‐free quantification of proteins, polymers and water density within individual biomolecular condensates. By transforming complex vibrational fingerprints into intuitive compositional maps, the approach reveals the high water content and structural heterogeneity of ...

A New Perspective on Path Integral Quantum Mechanics in Curved Space-Time

EPJ Web of Conferences, 2013
. A new approach to path integral quantum mechanics in curved space-time is presented for scalar particle propagation, expressed in terms of Lie transport and Fermi or Riemann normal co-ordinates to describe local curvature.

Solution of the Fokker-Planck equation with boundary conditions by Feynman-Kac integration. [PDF]

In this paper, we apply the results about d and d-function perturbations in order to formulate within the Feynman-Kac integration the solution of the forward Fokker-Planck equation subject to Dirichlet or Neumann boundary conditions.

Strongly Anisotropic and Rapid Excitons Transport in Organic Crystal

Advanced Science, EarlyView.
The increased exciton diffusion length is beneficial to simplify device design and enhance photoelectric conversion efficiency. But the isotropic exciton diffusion may lead to reduced transport efficiency directed to the charge separation site. Here we have successfully achieved strongly anisotropic and rapid excitons transport in thienopyrrole ...

A solution of 3D Helmholtz equation for boundary geometry modeled by Coons patches using the Parametric Integral Equation System

Archives of Acoustics, 2014
In this paper, the authors propose an algorithm for numerical solution of the 3D Helmholtz equation using the Parametric Integral Equation System (PIES). The PIES, unlike the traditional Boundary Integral Equation (BIE), is characterized by the fact that

Unravelling AdS3/CFT2 near the boundary

Journal of High Energy Physics
We study correlation functions of spectrally-flowed vertex operators in bosonic string theory on AdS3 × 𝑋 in the path integral formalism. By restricting the path integral to only include worldsheets which live near the asymptotic boundary, we compute ...

Green's Functions of Non‐Hermitian Systems at Exceptional Deficiency

Advanced Science, EarlyView.
We analyze the responses of a non‐Hermitian lattice system under the condition of exceptional deficiency (ED), when all bands in the system are formed by exceptional points. Using the frequency domain, we identify novel steady‐state responses that root in the broadband super‐Lorentzian Green's function (GF).

Electroweak three-body decays in the presence of two- and three-body bound states

Journal of High Energy Physics
Recently, formalism has been derived for studying electroweak transition amplitudes for three-body systems both in infinite and finite volumes. The formalism provides exact relations that the infinite-volume amplitudes must satisfy, as well as a ...
