Generalization of Gisin’s theorem to quantum fields
We generalize Gisin’s theorem on the relation between the entanglement of pure states and Bell non-classicality to the case of mode entanglement of separated groups of modes of quantum fields extending the theorem to cover also states with undefined ...

Structure of light-front vacuum sector diagrams
We study the structure of scalar field light-front quantization vacuum graphs. In instant-time quantization both non-vacuum and vacuum graphs can equivalently be described by either the off-shell four-dimensional Feynman diagram approach or the on-shell ...

Bond and Antibond Resonances: A Unified Framework for Singlet Biradical Character
The electronic structure of a variety of singlet biradicaloids may be described in the Lewis picture using single antibonds as the central bonding motif. In conjunction with a consistent set of biradical indicators, we can resolve some long‐standing disputes over the biradical character of molecules such as O3 and S2N2.

Gravitational Scattering Amplitudes and Closed String Field Theory in the Proper-Time Gauge
We construct a covariant closed string field theory by extending recent works on the covariant open string field theory in the proper-time gauge. Rewriting the string scattering amplitudes generated by the closed string field theory in terms of the ...

DFT analysis of d7 pseudo‐octahedral Ni(III) complexes reveals Jahn–Teller elongation (ΔR ≈ 0.15–0.23 Å) analogous to d9 Cu(II) systems. Elongated structures are minima, while compressed geometries are saddle points with small stabilization energies (ΔEJT ≈ 0.02–0.04 eV).

Quantum computational logics and Fock space semantics
The theory of logical gates in quantum computation has suggested new forms of quantum logic, called quantum computational logics. The basic semantic idea is the following: the meaning of a sentence is identified with a quantum information quantity ...

Teleportation of a qubit using quasi-Bell states
In this paper, we study the exotic Landau problem at the classical level where two conserved quantities are derived. At the quantum level, the corresponding quantum operators of the conserved quantities provide two oscillator representations from which ...

2×2 operator matrix with real parameter and its spectrum [PDF]
In the present paper we consider a linear bounded self-adjoint 2×2 block operator matrix Aμ (so called generalized Friedrichs model) with real parameter μ ∈ R.

ABSTRACT The rational design of lanthanide‐based luminescent systems using purely theoretical approaches remains challenging due to the reliance of existing models on experimental data. Herein, we propose a theoretical protocol for the design of new Eu3+ based luminescent systems, starting from a previously synthesized and experimentally characterized ...
