Solid State Defect Emitters With no Electrical Activity

open access: yesAdvanced Science, EarlyView.
Point defects may introduce in‐gap states that alter electrical properties and lower the optical excitation threshold. It is thus widely assumed that solid‐state defect emitters alter the host conductivity. This study demonstrates, on a particular defect in 4H silicon carbide, that a yet unrecognized class of point defects exists that are optically ...

Improving the positive feedback adiabatic logic familiy [PDF]

open access: yesAdvances in Radio Science, 2004
Positive Feedback Adiabatic Logic (PFAL) shows the lowest energy dissipation among adiabatic logic families based on cross-coupled transistors, due to the reduction of both adiabatic and non-adiabatic losses.

Amyloid Forming Human Lysozyme Intermediates are Stabilized by Non‐Native Amide‐π Interactions

open access: yesAdvanced Science, EarlyView.
Mutational variants of human lysozyme cause fatal systemic amyloidosis by depositing kilograms of protein in the viscera of patients. Central to this process is a partially unfolded protein intermediate state that initiates aggregation into amyloid fibrils.

Characteristic of an adiabatic charging reversible circuit with a Lithium ion capacitor as an energy storage device

open access: yesResults in Physics, 2018
An adiabatic reversible circuit was designed for charging a Lithium ion capacitor. The duty ratio of the switching transistors is digitally controlled by a microprocessor.

Unveiling the Fundamental Principles of Reconfigurable Resistance States in Silver/Poly(Ethylene Glycol) Nanofluids

open access: yesAdvanced Science, EarlyView.
The electrophoretic reorganization of Ag nanoparticles within a poly(ethylene glycol) leads to the formation of conductive bridges with reconfigurable resistance states. Diverse conduction characteristics of the bridge range between ohmic conduction, nonlinear tunneling, or space charge‐limited conduction, and high resistance states.

Transfer of solitons and half-vortex solitons via adiabatic passage

open access: yesPhysical Review Research
We show that the transfer of matter-wave solitons and half-vortex solitons in a spin-orbit coupled Bose-Einstein condensate between two (or more) arbitrarily chosen sites of an optical lattice can be implemented using the adiabatic passage.
