The sum of unitary similarity orbits containing only special operators
, 2009 Let B(H) be the algebra of bounded linear operator acting on a Hilbert space H (over the complex or real field). Characterization is given to A1,…,Ak∈B(H) such that for any unitary operators U1,…,Uk,∑j=1kUj∗AjUj is always in a special class S of ...

Conceptualizing Corporate Political Activity for Sustainability Governance—The CPA Cube
Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability transformations in the economy, and related public policy decisions, are highly contested, attracting business involvement. To better understand how business influence on government impacts the success or failure of sustainability governance efforts, this paper extends the literature on corporate political activity (CPA) by ...

Quantum simulation of two-level PT-symmetric systems using Hermitian Hamiltonians
Physical Review ResearchParity-time (PT)-symmetric Hamiltonians exhibit nonunitary dynamical evolution while maintaining real spectra, and offer unique approaches to quantum sensing and entanglement generation. Here, we present a method for simulating the quantum dynamics of PT-

Similarity renormalization group for nucleon-nucleon interactions [PDF]
, 2007 The similarity renormalization group (SRG) is based on unitary transformations that suppress off-diagonal matrix elements, forcing the Hamiltonian toward a band-diagonal form.

The Canadian Journal of Chemical Engineering, EarlyView.Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Quantum-enhanced t-stochastic neighbor embedding for high-dimensional data visualization
Physical Review Researcht-distributed stochastic neighbor embedding (t-SNE) is a nonlinear dimensionality reduction algorithm that preserves local similarity by matching probability distributions between high- and low-dimensional spaces.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

ParticlesI propose a data-driven surrogate model for the In-Medium Similarity Renormalization Group (IMSRG) method using Dynamic Mode Decomposition (DMD). First, the Magnus formulation of the IMSRG is leveraged to represent the unitary transformation of many-body

Unitary equivalence of one-parameter groups of Toeplitz and composition operators
, 2011 The composition operators on H2 whose symbols are hyperbolic automorphisms of the unit disk fixing ±1 comprise a one-parameter group and the analytic Toeplitz operators coming from covering maps of annuli centered at the origin whose radii are ...
