Physical spin torques from exactly constrained exchange-correlation torques

Jacques K. Desmarais, Kamel Bencheikh, Giovanni Vignale +1

The problem of capturing physical spin torques in non-collinear magnetic systems has dominated the scene of spin-density functional theory (SDFT) in the last two decades. Progress…

Analytic solution to degenerate biphoton states generated in arrays of nonlinear waveguides

Jefferson Delgado-Quesada, David Barral, Kamel Bencheikh +1

The arrays of nonlinear waveguides are a powerful integrated photonics platform for studying and manipulating quantum states of light. Also, they are a valuable resource for variou…

Electron localization function for non-collinear spins

Jacques K. Desmarais, Giovanni Vignale, Kamel Bencheikh +2

Understanding of bonding is key to modelling materials and predicting properties thereof. A widely adopted indicator of bonds and atomic shells is the electron localization functio…

Preserving the Hermiticity of the One-Body Density Matrix for a Non-Interacting Fermi Gas

L. M. Farrell, D. Eaton, P. Chitnelawong +2

The one-body density matrix (ODM) for a zero temperature non-interacting Fermi gas can be approximately obtained in the semiclassical regime through different -expansion tec…

Diverse Entanglement Mechanisms in Multimode Nonlinear Continuous Variables

Da Zhang, David Barral, Yanpeng Zhang +1

Non-Gaussian entangled states play a crucial role in harnessing quantum advantage in continuous-variable quantum information. However, how to fully characterize N-partite (N > 3) n…

Certification of non-Gaussian Einstein-Podolsky-Rosen Steering

Mingsheng Tian, Zihang Zou, Da Zhang +5

Non-Gaussian quantum states are a known necessary resource for reaching a quantum advantage and for violating Bell inequalities in continuous variable systems. As one kind of manif…
