Quantum simulation of two-level PT-symmetric systems using Hermitian Hamiltonians

Physical Review Research
Parity-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-

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-enhanced t-stochastic neighbor embedding for high-dimensional data visualization

Physical Review Research
t-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.

A Paradox Perspective on Business Model Innovation in Sustainability‐Oriented Industries: A Longitudinal Case Study in the Energy Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how Business Model Innovation (BMI) unfolds in sustainability‐oriented industries, where institutional complexity, technological interdependence, and environmental imperatives generate persistent sustainability‐related paradoxical tensions.

Surrogate Model for In-Medium Similarity Renormalization Group Method Using Dynamic Mode Decomposition

Particles
I 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

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

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 ...

A complete unitary similarity invariant for unicellular matrices

Linear Algebra and its Applications, 2011
We present necessary and sufficient conditions for an n\times n complex matrix B to be unitarily similar to a fixed unicellular (i.e., indecomposable by similarity) n\times n complex matrix ...

Modified F‐tests for assessing tree radial growth under linear‐circular regression models with correlated errors: A comprehensive toolbox rooted in G. E. P. Box's theorems

Canadian Journal of Statistics, EarlyView.
Abstract Annual tree growth is a complex biological process. Modelling radial growth in the trunk by linear‐circular regression with one mode and correlated errors has allowed the definition and assessment of a preferred direction for 1 and 2 years. Here, modified F$$ F $$‐tests are presented for 3 years, 1 mode/year; 1 year, 2 modes for possible main ...
