Lectures on integrable Hamiltonian systems [PDF]
arXiv, 2013 We consider integrable Hamiltonian systems in a general setting of invariant submanifolds which need not be compact. For instance, this is the case a global Kepler system, non-autonomous integrable Hamiltonian systems and integrable systems with time-dependent parameters.

arXiv, 2004 This article is a short introduction to the general topic of quantum spin systems. After a brief sketch of the history of the subject, the standard mathematical framework for formulating problems and results in quantum spin systems is described. Then, three short sections are devoted to Spontaneaous Symmetry Breaking, Phase transitions, and Dynamcis.

A Flexible Photovoltaic Fatigue Factor for Quantification of Mechanical Device Performance
Advanced Functional Materials, EarlyView.The flexible Photovoltaic fatigue factor (F) quantifies mechanical and photovoltaic performance as a function of the power conversion efficiency (PCE), the strain (ε${\varepsilon}$), and the number of bending cycles (NBC) in bending tests. The strain depends on the bending radius (R) and the thicknesses of the substrate (ts) and the photovoltaic device

Re-formulation of combined system wave-function formalism [PDF]
arXiv, 2006 We introduce a formulation of combined systems in orthodox non-relativistic quantum mechanics, mathematically equivalent to the usual one. For context and larger issues, see http://euclid.unh.edu/~jjohnson/axiomatics.html and http://arxiv.org/quant-ph ...

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery
Advanced Functional Materials, EarlyView.The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Advanced Functional Materials, EarlyView.This study investigates the role of hole‐blocking layers (HBLs), particularly the combination of two HBLs in photomultiplication‐type organic photodetectors (PM‐OPDs), which results in high gain and record‐fast response. The proposed HBL strategy also allows for the use of photoactive layer with balanced donor–acceptor stoichiometry, which can be ...

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide
Advanced Functional Materials, EarlyView.This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

On ground state phases of quantum spin systems [PDF]
arXiv, 2012 In this short note, I review some recent results about gapped ground state phases of quantum spin systems and discuss the notion of topological order.
