Design for material properties of additively manufactured metals using topology optimization

Materials & Design, 2023
In metal Additive Manufacturing (AM), the deposited material is subjected to a series of heating and cooling cycles. The locally occurring temperature extremes and cooling rates determine solid-state phase fractions, material microstructure, texture, and

A Single Laser System for Ground-State Cooling of 25-Mg+

, 2011
We present a single solid-state laser system to cool, coherently manipulate and detect $^{25}$Mg$^+$ ions. Coherent manipulation is accomplished by coupling two hyperfine ground state levels using a pair of far-detuned Raman laser beams.

Novel mechanocaloric materials for solid-state cooling applications [PDF]

Applied Physics Reviews, 2019
Current refrigeration technologies based on compression cycles of greenhouse gases are environmentally threatening and cannot be scaled down to on-chip dimensions. Solid-state cooling is an environmentally friendly and highly scalable technology that may solve most of the problems associated with current refrigerant methods.

Cooling of the Nuclear Spin System of a Nanostructure by Oscillating Magnetic Fields

Nanomaterials, 2023
We propose a method of cooling nuclear spin systems of solid-state nanostructures by applying a time-dependent magnetic field synchronized with spin fluctuations. Optical spin noise spectroscopy is considered a method of fluctuation control. Depending on

Exciton-polaritons gas as a nonequilibrium coolant

, 2015
Using angle-resolved Raman spectroscopy, we show that a resonantly excited ground-state exciton-polariton fluid behaves like a nonequilibrium coolant for its host solid-state semiconductor microcavity.
