A tutorial on quantum scattering theory and coupled-channel calculations of bimolecular collisions
Karl P. Horn, Christiane P. Koch
Collisions between atoms and molecules govern how energy is exchanged and redistributed in the gas phase, underpinning phenomena from spectral line broadening and interstellar mole…
Collision inside an atom: quantum ion-atom dynamics
Arijit Das, Yufeng Wang, Marcin Welter +6
Rydberg atoms occupy a central role in quantum science; their loosely bound outer electron gives rise to properties that enable quantum information processing1 or the formation of…
Quantitative Classical Relaxation Dynamics of Penning-Ionized He/Ne--H/HD Complexes
Meenu Upadhyay, Baruch Margulis, Octavio Roncero +3
Penning ionization allows {\it in situ} generation of ionic complexes to launch vibrational relaxation and dissociation dynamics for rare gas--H/HD complexes. The ensuing…
Feshbach Resonances in Cold Collisions: Benchmarking State of the Art ab initio Potential Energy Surfaces
Karl P. Horn, Meenu Upadhyay, Baruch Margulis +4
High-quality potential energy surfaces (PES) are a prerequisite for quantitative atomistic simulations, with both quantum and classical dynamics approaches. The ultimate test for t…
Improving Potential Energy Surfaces Using Experimental Feshbach Resonance Tomography
Karl P. Horn, Luis Itza Vazquez-Salazar, Christiane P. Koch +1
The structure and dynamics of a molecular system is governed by its potential energy surface (PES), representing the total energy as a function of the nuclear coordinates. Obtainin…
Tomography of Feshbach Resonance States
Baruch Margulis, Karl P. Horn, Daniel M. Reich +8
Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules. Here we present the detectio…
Resource-efficient dissipative entanglement of two trapped-ion qubits
Daniel C. Cole, Stephen D. Erickson, Giorgio Zarantonello +7
We demonstrate a simplified method for dissipative generation of an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher f…
Krotov: A Python implementation of Krotov's method for quantum optimal control
Michael H. Goerz, Daniel Basilewitsch, Fernando Gago-Encinas +4
We present a new open-source Python package, krotov, implementing the quantum optimal control method of that name. It allows to determine time-dependent external fields for a wide…
Quantum optimal control of the dissipative production of a maximally entangled state
Karl P. Horn, Florentin Reiter, Yiheng Lin +2
Entanglement generation can be robust against noise in approaches that deliberately incorporate dissipation into the system dynamics. The presence of additional dissipation channel…
