New Results on Negative-Indexed Pell Numbers via Matrix Methods
Cumhuriyet Science JournalIn this study, we investigate the Pell and Pell–Lucas numbers sequences and construct matrices whose elements are defined using negative indices of these sequences through Binet’s formula. Identities involving negative-indexed Pell and Pell–Lucas numbers

Superstatistics in Random Matrix Theory
Sultan Qaboos University Journal for Science, 2012 Random matrix theory (RMT) provides a successful model for quantum systems, whose classical counterpart has chaotic dynamics. It is based on two assumptions: (1) matrix-element independence, and (2) base invariance.

Density Matrix Perturbation Theory [PDF]
Physical Review Letters, 2004 An expansion method for perturbation of the zero temperature grand canonical density matrix is introduced. The method achieves quadratically convergent recursions that yield the response of the zero temperature density matrix upon variation of the Hamiltonian.

Matrix-Sequences of Geometric Means in the Case of Hidden (Asymptotic) Structures
MathematicsIn the current work, we analyze the spectral distribution of the geometric mean of two or more matrix-sequences constituted by Hermitian positive definite matrices, under the assumption that all input matrix-sequences belong to the same Generalized ...

Narrative Matrix Theory: An integrated framework that incorporates management theory and narrative
AAOS Transactions, 2022 Recently, management theories such as knowledge creation, ambidextrous organization, and dynamic capability have gained attention. However, an issue is that there is no structured way to understand and apply them in an integrated way in practice ...

, 2010 The different facets of the $R$-matrix method are presented pedagogically in a general framework. Two variants have been developed over the years: $(i)$ The "calculable" $R$-matrix method is a calculational tool to derive scattering properties from the ...

On the S-matrix of Liouville theory
Journal of High Energy Physics, 2021 The S-matrix for each chiral sector of Liouville theory on a cylinder is computed from the loop expansion of correlation functions of a one-dimensional field theory on a circle with a non-local kinetic energy and an exponential potential.

Canonical density matrix perturbation theory
, 2015 Density matrix perturbation theory [Niklasson and Challacombe, Phys. Rev. Lett. 92, 193001 (2004)] is generalized to canonical (NVT) free energy ensembles in tight-binding, Hartree-Fock or Kohn-Sham density functional theory. The canonical density matrix

Confinement/deconfinement transition in the D0-brane matrix model — A signature of M-theory?
Journal of High Energy Physics, 2022 We study the confinement/deconfinement transition in the D0-brane matrix model (often called the BFSS matrix model) and its one-parameter deformation (the BMN matrix model) numerically by lattice Monte Carlo simulations.
