Operator Homology and Cohomology in Clifford Algebras
Cubo, 2010 In recent work, the authors used canonical lowering and raising operators to define Appell systems on Clifford algebras of arbitrary signature. Appell systems can be interpreted as polynomial solutions of generalized heat equations, and in probability ...

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.Nonlinear photocurrents provide broadband spectroscopic access to quantum materials from terahertz to optical frequencies. Their sensitivity to spin, orbital, chiral, topological, and quantum‐geometric properties enables insights across ferroelectrics, magnetic and two‐dimensional materials, moiré heterostructures, topological flat bands, and light ...

A corner reflector of graphene Dirac fermions as a phonon-scattering sensor
Nature Communications, 2019 Dirac fermion optics leverages p-n junctions and Klein tunnelling barriers present in materials to implement complex optical functions and devices, including reflectors, collimators, and Dirac fermion microscopes.

Finite‐Time Protocols Stabilize Charging in Noisy Ising Quantum Batteries
Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.A transverse‐field quantum Ising chain is charged as a quantum battery using finite‐time ramps, which suppress energy oscillations and stabilize charging compared to sudden quenches. When time‐correlated noise is introduced, the outcome depends entirely on the protocol: noise can either boost stored energy or improve efficiency, never both ...

Radiative instability of quantum electrodynamics in chiral matter
Physics Letters B, 2018 Modification of the photon dispersion relation in chiral matter enables 1→2 scattering. As a result, the single fermion and photon states are unstable to photon radiation and pair production respectively.

From Moral Supervenience to Moral Contingentism (In One Easy Step!)
Analytic Philosophy, Volume 67, Issue 3, Page 224-237, September 2026.ABSTRACT According to the Divide & Conquer (DC) strategy (Fogal and Risberg 2020) for explaining moral supervenience, the modal covariation between moral and natural properties can be partly explained by appeal to pure moral principles. Bhogal (2022) has recently argued that DC fails.

Bosonization of Fermionic Fields and Fermionization of Bosonic Fields [PDF]
Advances in Applied Clifford Algebras, 2017 In this paper using the Clifford and spin-Clifford bundles formalism we show how Weyl and Dirac equations formulated in the spin-Clifford bundle may be written in an equivalent form as generalized Maxwell like form formulated in the Clifford bundle. Moreover, we show how Maxwell equation formulated in the Clifford bundle formalism can be written as an ...

Exploiting Structure in Krylov Subspace Methods for the Wilson Fermion Matrix
, 1997 this paper is to reveal the algorithmic progress for solving (1) that has been achieved within the last 3 years. We deal with the following topics: (i) the structure of the Wilson fermion matrix M , (ii) algorithmic progress by using efficient Krylov ...

Boson-fermion mapping of collective fermion-pair algebras
, 1995 We construct finite Dyson boson-fermion mappings of general collective algebras extended by single-fermion operators. A key element in the construction is the implementation of a similarity transformation which transforms boson-fermion images obtained ...

Edge Density Expansions for the Classical Gaussian and Laguerre Ensembles
Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.ABSTRACT Recent work of Bornemann has uncovered hitherto hidden integrable structures relating to the asymptotic expansion of quantities at the soft edge of the Gaussian and Laguerre random matrix ensembles. These quantities are spacing distributions and the eigenvalue density, and the findings cover the cases of the three symmetry classes: orthogonal,
