An Information-Theoretic Law Governing Human Multi-Task Navigation Decisions

Nicholas Sohre, Alisdair O. G. Wallis, Stephen J. Guy

To better understand the process by which humans make navigation decisions when tasked with multiple stopovers, we analyze motion data captured from shoppers in a grocery store. We…

Customer mobility and congestion in supermarkets

Fabian Ying, Alisdair O. G. Wallis, Mariano Beguerisse-Díaz +2

The analysis and characterization of human mobility using population-level mobility models is important for numerous applications, ranging from the estimation of commuter flows in…

Traces on ion yields and electron spectra of Ar inner-shell hollow states with Free-Electron Lasers

A. O. G. Wallis, H. Banks, A. Emmanouilidou

We explore the formation by Free-Electron-Laser radiation of Ar hollow states with two or three inner-shell holes. We find that even charged Ar ion states can be more populated tha…

Auger spectra following inner-shell ionization of Argon by a Free-Electron Laser

Alisdair O. G. Wallis, L. Lodi, A. Emmanouilidou

We explore the possibility of retrieving Auger spectra with FEL radiation. Using a laser pulse of 260 eV photon energy, we study the interplay of photo-ionization and Auger process…

Magnetic Feshbach resonances in collisions of non-magnetic closed-shell molecules

Alisdair O. G. Wallis, Roman V. Krems

Magnetic Feshbach resonances play a central role in experimental research of atomic gases at ultracold temperatures, as they allow one to control the microscopic interactions betwe…

Optically induced conical intersections in traps for ultracold atoms and molecules

Alisdair O. G. Wallis, Jeremy M. Hutson

We show that conical intersections can be created in laboratory coordinates by dressing a parabolic trap for ultracold atoms or molecules with a combination of optical and static m…

Rotational predissociation of extremely weakly bound atom-molecule complexes produced by Feshbach resonance association

Alisdair O. G. Wallis, Roman V. Krems

We study the rotational predissociation of atom - molecule complexes with very small binding energy. Such complexes can be produced by Feshbach resonance association of ultracold m…

Multichannel Quantum Defect Theory for cold molecular collisions

James F. E. Croft, Alisdair O. G. Wallis, Jeremy M. Hutson +1

Multichannel Quantum Defect Theory (MQDT) is shown to be capable of producing quantitatively accurate results for low-energy atom-molecule scattering calculations. With a suitable…

The prospects of sympathetic cooling of NH molecules with Li atoms

Alisdair O. G. Wallis, Edward J. J. Longdon, Piotr S. Żuchowski +1

We calculate the quartet potential energy surface for Li+NH and use it to calculate elastic and spin-relaxation cross sections for collisions in magnetically trappable spin-stretch…

Production of ultracold NH molecules by sympathetic cooling with Mg

Alisdair O. G. Wallis, Jeremy M. Hutson

We carry out calculations on -changing collisions of NH () molecules in magnetically trappable states using a recently calculated potential energy surface. We show that e…

Conical intersections in laboratory coordinates with ultracold molecules

Alisdair O. G. Wallis, S. A. Gardiner, Jeremy M. Hutson

For two states of opposite parity that cross as a function of an external magnetic field, the addition of an electric field will break the symmetry and induce an avoided crossing.…
