Vibrational strong coupling influences product selectivity in a model for post transition state bifurcation reactions

This study demonstrates that vibrational strong coupling within an optical cavity can significantly enhance product selectivity in post-transition state bifurcation reactions by altering dynamical outcomes through cavity-system and intramolecular energy transfer, thereby establishing cavity quantum electrodynamics as a viable tool for reshaping chemical reaction pathways.

Helical orbitals in electrical uni-directional molecular motors

This paper proposes a mechanism for electrical uni-directional molecular motors driven by electron current through helical orbitals, introduces a formal definition of helicality to link electronic angular momentum with rotational direction, and predicts that approximate sub-lattice symmetry causes the motor's sense of rotation to remain independent of the current direction.

On the generalized eigenvalue problem in subspace-based excited state methods for quantum computers

This paper demonstrates that subspace-based excited state methods like QSE and qEOM suffer from severe instability due to the amplification of sampling errors by the condition number of the overlap matrix, whereas methods like q-sc-EOM that rely on standard eigenvalue equations offer a more robust and suitable alternative for quantum chemistry calculations on noisy quantum devices.
