First-principles design and subsequent synthesis of a material to search for the permanent electric dipole moment of the electron

open access: yes, 2010
We describe the first-principles design and subsequent synthesis of a new material with the specific functionalities required for a solid-state-based search for the permanent electric dipole moment of the electron. We show computationally that perovskite-

Ultrafast Energy Transfer Induced Lasing From a Coplanar Donor‐Acceptor‐Donor Molecule in a Microspherical Cavity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

Single-domain ferromagnet of noncentrosymmetric uniaxial magnetic ions and magnetoelectric interaction [PDF]

open access: yes, 2017
The feasibility of a single-domain ferromagnet based on uniaxial magnetic ions was examined. For a noncentrosymmetric uniaxial magnetic ion of magnetic moment at a site of local electric dipole moment p, it is unknown to date whether the magnetic moment prefers to be parallel or antiparallel to the electric dipole moment.

The effects of magnetic fields on magnetic dipole moments [PDF]

open access: yesarXiv, 2021
We calculate the effect of magnetic fields on the magnetic dipole moment of leptons up to the quadratic order in the magnetic field, including the QCD contributions. Since the leading contribution, which is linear in the magnetic field, depends on the spin, its effect is not measurable directly in the Penning trap experiment for the electron dipole ...

QED theory of the nuclear magnetic shielding in hydrogen-like ions

open access: yes, 2011
The shielding of the nuclear magnetic moment by the bound electron in hydrogen-like ions is calculated ab initio with inclusion of relativistic, nuclear, and quantum electrodynamics (QED) effects.

Perovskite Light‐Emitting Diodes with Quantum Wires and Nanorods

open access: yesAdvanced Materials, EarlyView.
This review focuses on low‐dimensional perovskite materials and discusses their applications in light‐emitting diodes (LEDs). Special attention is given to the introduction of perovskite quantum wires and nanorods, two unique types of one‐dimensional (1D) materials, and their interesting optoelectronic properties.

Fe clusters (Fe$_n$, n=1-6) chemisorbed on vacancy defects in graphene: Stability, spin-dipole moment and magnetic anisotropy [PDF]

open access: yes, 2014
In this work, we have studied the chemical and magnetic interactions of Fe$_n$ ; n=1-6 clusters with vacancy defects (monovacancy to correlated vacancies with six missing C atoms) in a graphene sheet by ab-initio density functional calculations combined with Hubbard U corrections for correlated Fe- d electrons.

Magnetic and electric dipole constraints on extra dimensions and magnetic fluxes [PDF]

open access: yes, 2009
The propagation of charged particles and gauge fields in a compact extra dimension contributes to g - 2 of the charged particles. In addition, a magnetic flux threading this extra dimension generates an electric dipole moment for these particles.

Exciton Dynamics in Layered Halide Perovskite Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
This review discusses the exciton dynamics in layered halide perovskitelight‐emitting diodes (PeLEDs). It opens with a summary of the structural and photophysical aspects, followed by an exploration of controlling dimensionality and cascade exciton transfer in quasi‐2D PeLEDs.
