Excited states of holographic superconductors
In this paper we re-investigate the model of the anti-de Sitter gravity coupled to Maxwell and charged scalar fields, which has been studied as the gravitational dual to a superconductor for a long time since the famous work [Phys. Rev. Lett.

Hyperridge of triply excited states [PDF]
We present a theory for the definition and the reliable calculation of correlated wave functions of a special class of triply excited states and for their rigorous geometrical analysis. This class is named the three-electron ionization ladder (THEIL) and refers to the simultaneous excitation of three electrons in valence states near threshold ...

A model electronic Hamiltonian to describe low-lying d–d and metal-to-ligand charge-transfer excited states of [Fe(bpy)3]^2+ [PDF]
A simple practical method to compute both d–d and metal‐to‐ligand charge‐transfer (MLCT) excited states of iron(II) polypyridyl complexes is proposed for use in simulation studies. Specifically, a model electronic Hamiltonian developed previously for d–d

Prospects for Neutron Reactions on Excited States in High-Density Plasmas
With the reactions of high flux neutrons, such as in a DT plasma, there is a prospect of seeing new kinds of neutron-nucleus reactions for the first time.

Targeted excited state algorithms [PDF]
To overcome the limitations of the traditional state-averaging approaches in excited state calculations, where one solves and represents all states between the ground state and excited state of interest, we have investigated a number of new excited state algorithms. Building on the work of van der Vorst and Sleijpen [SIAM J. Matrix Anal. Appl. 17, 401 (

Excited states of holographic superconductors with hyperscaling violation
We employ the numerical and analytical methods to study the effects of the hyperscaling violation on the ground and excited states of holographic superconductors for d=2,z=2.

Excited states of holographic superconductors with backreaction
In this paper we investigate the model of the anti-de Sitter gravity coupled to a Maxwell field and a free, complex scalar field, and construct a fully back-reacted holographic model of superconductor with excited states.

Synthetic organic chemistry has seen major advances due to the merger of nickel and photoredox catalysis. A growing number of Ni-photoredox reactions are proposed to involve generation of excited nickel species, sometimes even in the absence of a ...

Excited state orbital optimization via minimizing the square of the gradient: General approach and application to singly and doubly excited states via density functional theory. [PDF]
We present a general approach to converge excited state solutions to any quantum chemistry orbital optimization process, without the risk of variational collapse.
