About Roy Glauber Open
We recount the life, work, and legacy of the theoretical physicist Roy Glauber (1925–2018). Admitted to Harvard at age 16, called upon to participate in the Manhattan Project at age eighteen, and appointed to the Harvard Physics faculty at…

Realization of Heisenberg models of spin systems with polar molecules in pendular states Open
Ultra-cold polar diatomic or linear molecules, oriented in an external electric field and mutually coupled by dipole–dipole interactions, can be used to realize the exact Heisenberg XYZ, XXZ and XY models without invoking any approximation.

Geometrical picture of the electron-electron correlation at the large-D limit Open
In electronic structure calculations, the correlation energy is defined as the difference between the mean field and the exact solution of the non relativistic Schrödinger equation. Such an error in the different calculations is not direct…

Thermodynamic feasibility of shipboard conversion of marine plastics to blue diesel for self-powered ocean cleanup Open
Significance Plastic waste accumulating in the world's oceans forms massive “plastic islands” in the oceanic gyres. Removing the plastic offers an opportunity to restore our oceans to a more pristine state. To clean the gyres, ships must c…

Dimensional Interpolation for Random Walk Open
We employ a simple and accurate dimensional interpolation formula for the shapes of random walks at $D=3$ and $D=2$ based on the analytically known solutions at both limits $D=\infty$ and $D=1$. The results obtained for the radii of gyrati…

Zdeněk Herman Open
In recent years physical chemist Zdeněk Herman, who died on 25 February 2021 in Prague, had been increasingly preoccupied with the startling opening of Charles Eliot’s book John Gilley of Baker’s Island: “To be absolutely forgotten in a fe…

Commentary: Chemical dynamics from the gas‐phase to surfaces Open
A trio of outstanding physical chemists, Daniel Auerbach, John Tully, and Alec Wodtke, has produced a superb review of the field of chemical dynamics.1 They stress "linkages between gas phase and surface chemical dynamics … a fruitful inte…

Generation of Methane in the Earth's Mantle: In situ High P-T Measurements of Carbonate Reduction Open
We present in situ observations of hydrocarbon formation via carbonate reduction at upper mantle pressures and temperatures. Methane was formed from FeO, CaCO{sub 3}-calcite and water at pressures between 5 and 11 GPa and temperatures rang…

Unorthodox Dimensional Interpolations for He, Li, Be Atoms and Hydrogen Molecule Open
We present a simple interpolation formula using dimensional limits $D=1$ and\n$D=\\infty$ to obtain the $D=3$ ground-state energies of atoms and molecules.\nFor atoms, these limits are linked by first-order perturbation terms of\nelectron-…

Pendular alignment and strong chemical binding are induced in helium dimer molecules by intense laser fields Open
Significance Intense electric fields, provided by pulsed lasers, can profoundly alter the electronic structure of atoms and molecules. For the helium dimer, we carry out a theoretical study of laser interactions in two realms: (I) fields n…

Confirmation of Kramers-Henneberger Atoms Open
In a remarkable experiment, Eichmann et al. attained unprecedented acceleration of neutral atoms by strong short-pulse IR laser fields. The driving mechanism was identified as the ponderomotive force on excited electrons bound in Rydberg o…

Quantum computation using arrays of N polar molecules in pendular states Open
We investigate several aspects of realizing quantum computation using entangled polar molecules in pendular states. Quantum algorithms typically start from a product state |00...0> and we show that up to a negligible error, the ground stat…
