Scientists Atoms-Thick Post-It Notes Solar Cells Circuits
2017/10/24
Over the past half-century, scientists have shaved silicon films down to just a wisp of atoms in pursuit of smaller, faster electronics. For the next set of breakthroughs, though, they’ll need novel w...
Stenciling with atoms in two-dimensional materials possible
Stenciling two-dimensional materials possible
2017/7/19
The possibilities for the new field of two-dimensional, one-atomic-layer-thick materials, including but not limited to graphene, appear almost limitless. In new research, Penn State material scientist...

2016/11/29
Atoms, photons, and other quantum particles are often capricious and finicky by nature; very rarely at a standstill, they often collide with others of their kind. But if such particles can be individu...
New Approach to Determining How Atoms Are Arranged in Materials
Atoms Are Arranged Materials
2016/9/12
A Bayesian inference method for refining crystallographic structures is presented. The distribution of model parameters is stochastically sampled using Markov chain Monte Carlo. Posterior probability ...

Chemistry in 1d via DMRG: Benchmarks for small atoms, ions, and molecules
Chemistry DMRG Benchmarks small atoms ions molecules
2012/2/24
The density matrix renormalization group (DMRG) method, an efficient solver of lattice models in 1d, has been adapted to solve real-space problems. We use DMRG to study the behavior of soft-Coulomb in...
Few-photon transport in a waveguide coupled to a pair of colocated two-level atoms
Few-photon transport waveguide coupled colocated two-level atoms
2015/8/7
We calculate the one- and two-photon scattering matrices of a pair of collocated nonidentical two-level atoms coupled to a waveguide. We show that by proper choice of a two-photon input, the backgroun...
First-principle electronic structure calculations within real-space mesh framework: Applications to atoms, molecules and nanostructures

This dissertation is organized as follows. Beginning with physical background discussions of many-body problems, Chapter 1 introduces the central Kohn-Sham equations of Density Functional Theory for e...
Designing Zeeman slower for strontium atoms – towards optical atomic clock
Zeeman slower, strontium, atomic clock
2011/5/9
We report on design and construction of a Zeeman slower for strontium atoms, which will be
used in an optical atomic clock experiment. The paper describes briefly required specifications of
the devi...
We demonstrate photoionization spectroscopy in cold rubidium atoms trapped in a working
magneto-optical trap. Three-photon ionization with two-photon resonance proceeds along various
channels, with ...
Novel Optogalvanic Spectroscopy of Semiconductor Atoms with a Frequency-tripled ns Ti:sapphire Laser Injection-seeded by a cw Frequency-scanning Ti:sapphire Laser
Deep-ultraviolet Injection seeding Optogalvanic spectroscopy
2009/6/1
Novel optogalvanic spectroscopy of silicon atoms was conducted with the narrow-linewidth nanosecond pulsed deep-ultraviolet coherent light source which was comprised of the frequency-tripled nanosecon...
The effects of boron impurity atoms on nickel Σ 5 (012) grain boundary by first principles calculations
Ab-initio calculation Stress corrosion cracking Tensile test
2010/2/4
Purpose: Impurity atoms in the grain boundary can be responsible for embrittlement or they can strengthen a material. In this work, we have modeled the effect of B impurity on Σ 5 (012) symmetrical ti...
