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

Limits on CP-violating hadronic interactions and proton EDM from paramagnetic molecules

open access: yesJournal of High Energy Physics, 2020
Experiments with paramagnetic ground or metastable excited states of molecules (ThO, HfF+, YbF, YbOH, BaF, PbO, etc.) provide strong constraints on the electron electric dipole moment (EDM) and the coupling constant C SP of contact semileptonic ...

A Method for Measuring the $6S_{1/2} \leftrightarrow 5D_{3/2}$ Magnetic Dipole Transition Moment in {Ba}$^{+}$

open access: yes, 2013
We propose a method for measuring the magnetic dipole (M1) transition moment of the $6S_{1/2} \big(\mathrm{m}=-1/2\big)\leftrightarrow 5D_{3/2}\big(\mathrm{m}=-1/2\big)$ transition in single trapped Ba$^{+}$ by exploiting different symmetries in the ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Investigation of the Effects of Strain and Electric Field on the Spin‐State Energetics of Co‐Doped BaTiO3 and PbTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Ab initio calculations using the r2SCAN functional show that biaxial strain does not alter the high spin preference of cobalt‐doped BaTiO3 and PbTiO3; a small compressive uniaxial strain however results in an equally favorable low spin state for BaTiO3 and thus bistable magnetism.

High Performance Room Temperature Multiferroic Properties of w‐MnSe Altermagnet

open access: yesAdvanced Functional Materials, EarlyView.
Using first‐principles calculations, for the first time the Altermagneto‐Ferroelectric Coupling Effect (AFCE) is proposed, which enables control of both electric polarization and spin splitting in the band structure due to polyhedral rotations. This uncovers robust multiferroicity in wurtzite MnSe at room temperature, offering an exciting route for ...

Noncommutative electrodynamics from $$SO(2,3)_\star $$ SO(2,3)⋆ model of noncommutative gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
In our previous work we have constructed a model of noncommutative (NC) gravity based on $$SO(2,3)_\star $$ SO(2,3)⋆ gauge symmetry. In this paper we extend the model by adding matter fields: fermions and a U(1) gauge field.

Neutrino masses and magnetic moments of electron and muon in the Zee Model

open access: yesJournal of High Energy Physics, 2022
We explore parameter space in the Zee Model to resolve the long-standing tension of the electron and muon anomalous magnetic moment (AMM). The model comprises a second Higgs doublet and a charged singlet at electroweak scale and generates Majorana ...

Graft Copolymer‐Stabilized Liquid Metal Nanoparticles for Lithium‐Ion Battery Self‐Healing Anodes

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a self‐healing liquid metal anode for lithium‐ion batteries, where graft copolymer‐stabilized eutectic gallium indium (EGaIn) nanoparticles enhance stability and rate performance. The fluorinated grafted copolymer forms ionic channels, preventing EGaIn aggregation and facilitating lithium‐ion migration.
