Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

open access: yesAdvanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Parametric resonance for pedestrians: From a swing to squeezing the quantum vacuum [PDF]

open access: yesAIP Advances
Taking the classical pendulum as its starting point, this paper unearths the profound physics hidden within this familiar model and constructs an investigative path that links macroscopic classical mechanics to microscopic quantum mechanics. Using MATLAB,

Chiral Phase Change Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Observability of localized magnetoplasmons in quantum dots: Scrutinizing the eligibility of far-infrared, Raman, and electron-energy-loss spectroscopies

open access: yesAIP Advances, 2016
We investigate a one-component, quasi-zero dimensional, quantum plasma exposed to a parabolic potential and an applied magnetic field in the symmetric gauge.

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

open access: yesAdvanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Measurement of the dineutrino system kinematic variables in dileptonic top quark pair production in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics
Differential top quark pair production cross sections are measured in the dilepton final states e+e − , μ+μ − , and e ± μ∓, as a function of kinematic variables of the two-neutrino system: the transverse momentum p T νν $$ {p}_{\textrm{T}}^{\nu \nu ...

Large loop-coupling enhancement of a heavy pseudoscalar from a light dark sector

open access: yesNuclear Physics B, 2017
The small background and the sensitivity to charged particles via a leading order loop coupling make the diphoton channel a privileged experimental test for new physics models.
