Fast and accurate excited states predictions: Machine learning and diabatization [PDF]
The efficiency of machine learning algorithms for electronically excited states is far behind ground-state applications. One of the underlying problems is the insufficient smoothness of the fitted potential energy surfaces and other properties in the ...

Are highly excited nuclear states merely chaotic? [PDF]
Increasing evidence suggests that we may not fully understand highly excited nuclear states. According to predictions from random matrix theory, which assumes that dynamical correlations are so strong that the underlying physical geometric structure is ...

A General Approach for Multireference Ground and Excited States using Non-Orthogonal Configuration Interaction [PDF]
A balanced description of ground and excited states is essential for the description of many chemical processes. However, few methods can handle cases where static correlation is present, and often these scale very unfavourably with system size. Recently,

Subsystem distances between quasiparticle excited states
We investigate the subsystem Schatten distance, trace distance and fidelity between the quasiparticle excited states of the free and the nearest-neighbor coupled fermionic and bosonic chains and the ferromagnetic phase of the spin-1/2 XXX chain.

Exploring the energy disposal immediately after bond-breaking in solution:the wavelength-dependent excited state dissociation pathways of para-methylthiophenol [PDF]
A wavelength-resolved (λpump = 295, 285, 270, and 267 nm) photodissociation study of para-methylthiophenol (p-MePhSH) in ethanol solution has been performed using femtosecond transient absorption (TA) spectroscopy, and the results compared with those ...

Chemical Bonding in Excited States: Electron Localization, Delocalization and Statistics in Real Space [PDF]
In this contribution, we continue with our enterprise regarding the systematization of chemical bonding in excited states. We show how real space electron localization and delocalization measures, coupled to the statistical analysis of electron number ...

Multi-State Density Functional Theory for Ground and Excited States [PDF]
We report a rigorous formulation of multi-state density functional theory (MSDFT) that extends the Kohn-Sham (KS) energy functional for the ground state to a Hamiltonian matrix functional H[D] of the density matrix D in the space spanned by the lowest N ...
