Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods
Contributions to Plasma Physics, EarlyView.ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

An Analytic Characterization of p,q-White Noise Functionals
Journal of Mathematics, 2020 In this paper, a characterization theorem for the S-transform of infinite dimensional distributions of noncommutative white noise corresponding to the p,q-deformed quantum oscillator algebra is investigated.

Contributions to Plasma Physics, EarlyView.ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Toeplitz Operators on Harmonic Fock Spaces with Radial Symbols
MathematicsThe main aim of this paper is to study new features and specific properties of the Toeplitz operator with radial symbols in harmonic Fock spaces. A new spectral decomposition of a Toeplitz operator with Wick symbols is also established.

Hankel Operators on Fock Spaces [PDF]
, 2013 We study Hankel operators on the weighted Fock spaces\ud Fp. The boundedness and compactness of these operators are characterized in terms of BMO and VMO, respectively. Along the way, we also study Berezin transform and harmonic conjugates on the plane.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Multiswitching between type‐II and Z‐scheme phases within a pristine In2Se3/SnSe heterostructure enable controllable carrier dynamics and enhanced photocatalytic performance. Two‐dimensional staggered heterostructures, featuring by the intrinsically facilitate charge separation, provide promising platforms for efficient photocatalytic water splitting ...

European Journal of Inorganic Chemistry, EarlyView.Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.

European Journal of Inorganic Chemistry, EarlyView.Two rubidium cations that are not fully encapsulated by 18‐crown‐6 are bridged by two pertechnetate units to form a dimer. These two pertechnetate units are nearly linearly aligned to each other to form Matere bonds (MaBs), a type of noncovalent σ‐hole interaction.
