How Good is the Transition-State Theory?
For the first time, the main assumption of the transition-state theory for the decay of complex quantum systems across a potential barrier was realized using a microscopic many-body Hamiltonian.

Estimating Beta Decay Rates Better for Exotic Nuclei
Physicists from Japan demonstrate an improved estimation of the beta decay rate in heavy nuclei by considering next-to-leading-order approximation for the electron wave function distorted by the Coulomb potential.

A Quantum Description of Physical Systems with Non-real Energies
While quantum systems are traditionally described by Hermitian Hamiltonians, the formalism is extendable to a non-Hermitian description for systems that are dissipative or obey parity-time symmetry.
