Vibrational Partition Functions from Bond Order and Populations Relationships
ChemPhysChem, EarlyView.A new computational model is presented that predicts vibrational partition functions using bond orders and populations relationships (QBOP). This model demonstrates that thermochemical energy contributions can be reasonably approximated based on well‐conditioned orbital populations without the need for a costly Hessian calculation.

ChemPhysChem, EarlyView.Range‐separated functionals, such as ωB97M‐D4, are shown to perform very well for reactions in acidic zeolites. Importantly, they work well with plane‐wave density functional theory and can thus be directly applied to periodic models at modest computational cost.

Hybrid coherent control of magnons in a ferromagnetic phononic resonator excited by laser pulses
Physical Review ResearchWe propose and demonstrate the concept of hybrid coherent control (CC) whereby a quantum or classical harmonic oscillator is excited by two excitations: one is quasiharmonic (i.e., harmonic with a finite lifetime) and the other is a pulsed broadband ...

ChemPhotoChem, EarlyView.Quantum chemistry has been used to investigate the key factors that determine the (reverse) intersystem crossing processes in boron‐based organic light‐emitting diode emitters. The ortho‐linked through‐space charge‐transfer compounds exhibit smaller singlet–triplet splittings than their para‐linked through‐bond charge‐transfer regioisomers.

Non-classical correlations beyond Bell’s inequality violation in qubit-pairs with an intrinsic noise
Results in Physics, 2019 In this paper, we analytically explore two qubits interacting with a coherent harmonic oscillator field under intrinsic noise. The interaction of the uncorrelated two qubits with a harmonic oscillator initially in the superposition of coherent states ...

ChemPhotoChem, EarlyView.The photophysical, electroluminescence, and amplified spontaneous emission properties of two solution‐processable fluorescent diketopyrrolopyrrole derivatives are examined in details. The results demonstrate that this type of organic near‐infrared light‐emitting materials are extremely promising for organic light‐emitting diodes and organic ...
