Observation of a resonant structure in e+e− → ωη and another in e+e− → ωπ0 at center-of-mass energies between 2.00 and 3.08 GeV

open access: yesPhysics Letters B, 2021
Born cross sections for the processes e+e−→ωη and e+e−→ωπ0 have been determined for center-of-mass energies between 2.00 and 3.08 GeV with the BESIII detector at the BEPCII collider.

Holographic superfluid with excited states

open access: yesPhysics Letters B, 2023
We construct a novel family of solutions of the holographic superfluid model with the excited states in the probe limit. We observe that the higher excited state or larger superfluid velocity will make the scalar hair more difficult to be developed, and ...

Modular flow of excited states

open access: yesJournal of High Energy Physics, 2021
We develop new techniques for studying the modular and the relative modular flows of general excited states. We show that the class of states obtained by acting on the vacuum (or any cyclic and separating state) with invertible operators from the algebra

Excited Kinks as Quantum States

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
At one loop, quantum kinks are described by a sum of quantum harmonic oscillator Hamiltonians, and so their spectra are known exactly. We find the first correction beyond one loop to the quantum states corresponding to kinks with an excited bound or ...

Density Functional Theory of Highly Excited States of Coulomb Systems

open access: yesComputation, 2021
The density functional theory proposed earlier for excited states of Coulomb systems is discussed. The localized Hartree–Fock (LHF) and the Krieger, Li, and Iafrate (KLI) methods combined with correlation are generalized for excited states.

Thermalization of holographic excited states

open access: yesJournal of High Energy Physics, 2022
We propose a real time holographic framework to study thermalization processes of a family of QFT excited states. The construction builds on Skenderis-van Rees’s holographic duals to QFT Schwinger-Keldysh complex-time ordered paths.

Targeted excited state algorithms [PDF]

open access: yesThe Journal of Chemical Physics, 2007
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 (

The role of Duschinsky rotation in intersystem crossing: A case study of uracil [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
The intersystem crossing rate for the transition between the lowest excited singlet and triplet electronic states of uracil was studied by means of ab initio methods.

Excited states of holographic superconductors

open access: yesJournal of High Energy Physics, 2020
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.

Prospects for Neutron Reactions on Excited States in High-Density Plasmas

open access: yesFrontiers in Physics, 2022
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.
