The photodissociation dynamics of the hydroxymethyl radical (CH2OH, CH2OD, and CD2OD) following excitation to the 3s and 3p(x) Rydberg states is studied using time-sliced velocity map imaging of hydrogen photofragments. Dissociation takes place on the ground potential energy surface reached via conical intersections from the excited states, and formaldehyde and hydrxymethylene are identified as...

The integrated density of states (IDS) for random operators is an important function describing many physical characteristics of a random system. Properties of the IDS are derived from the Wegner estimate that describes the influence of finite-volume perturbations on a background system. In this paper, we present a simple proof of the Wegner estimate applicable to a wide variety of random pertu...

Dielectric capacitors are particularly suitable to store the electrical energy of a fast-changing nature. Here, we present review recent applications first principles and first-principles-based effective Hamiltonian approaches study storage in ferroelectrics, lead-free antiferroelectrics, relaxor nitride semiconductors. Specifically, these used investigate density efficiency perovskite BaTiO 3 ...
