Quasistates in a ring coupled to a reservoir and their relation to the Dicke effect [PDF]
Physical Review B, 2003 We study the energy spectrum and the persistent current in an ideal one-dimensional mesoscopic ring coupled to an external fermionic reservoir. The contact between ring and reservoir is described by a tunneling operator, which causes an indirect coupling between different ring states via states in the reservoir. For strong coupling to the reservoir new

Quasi-stability of a vector trajectorial problem with non-linear partial criteria [PDF]
Computer Science Journal of Moldova, 2003 Multi-objective (vector) combinatorial problem of finding the Pareto set with four kinds of non-linear partial criteria is considered. Necessary and sufficient conditions of that kind of stability of the problem (quasi-stability) are obtained.

ChemSusChem, Volume 19, Issue 21, 12 November 2026.Localized Li+ interactions at vicinal dihydroxyl and carboxyl groups are accompanied by greater dissolution and interfacial reconstruction in naphthalene‐derived organic anodes, whereas more delocalized interactions in naphthalene and monohydroxylated derivatives favor active‐material retention and more stable cycling.

Advanced Intelligent Discovery, Volume 2, Issue 3, June 2026.To enable versatile unconventional computing, a single SiOx threshold switching device is engineered to exhibit controllable dual‐mode oscillation. By modulating the input voltage, the device selectively provides stable full oscillation for oscillatory neural networks and stochastic probabilistic oscillation for probabilistic bits and true random ...

Spectrum of quasistable states in a strong infrared field
Physical Review A, 2015 The stability of highly excited hydrogen and helium atoms subject to an intense infrared laser field is studied, and similarities to the case of microwave driving are discussed.

Revealing Two Operation Modes of Perovskite Light‐Emitting Diodes Through Overshoot Pulses
Advanced Photonics Research, Volume 7, Issue 1, January 2026.Short, high‐intensity overshoot pulses (OSPs) may be generated by perovskite light‐emitting diodes (PeLEDs) depending on electrical pump pulse parameters, offset and afterpulse voltages. OSPs reveal two PeLED operation modes: the recombination mode, favorable for the conventional EL but preventing OSPs, and the accumulation mode, enabling the formation

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Mining‐induced coal seam extraction causes deformation and fracturing of the overburden, leading to the development of fractures, which pose significant threats to mine safety, surface structures, and natural ecosystems. To address the challenge of quantitatively characterizing overburden fractures caused by coal seam mining, this study, taking the 12 ...

Complexity, Volume 2026, Issue 1, 2026.Seven of nine planetary boundaries have been transgressed and anthropogenic mass now exceeds all living biomass, yet existing collapse models assume ecological regeneration—contradicting tipping‐point evidence—while integrated assessment models rely on smooth damage functions that preclude irreversibility.

Coherence and quasistable states in a strong infrared field
Physical Review A, 2016 We study the quasistability of UV-pulse-train-excited H atoms in a strong infrared (IR) laser as a function of the phase delay of the UV pulse train relative to the IR laser. The UV pulse train contains two frequency components. When the two components have frequencies separated by two IR photons, the population of surviving electrons is modulated by ...

Clifford representatives via the uniform algebraic rank
Journal of the London Mathematical Society, Volume 111, Issue 6, June 2025.Abstract In this paper, we introduce the uniform algebraic rank of a divisor class on a finite graph. We show that it lies between Caporaso's algebraic rank and the combinatorial rank of Baker and Norine. We prove the Riemann–Roch theorem for the uniform algebraic rank, and show that both the algebraic and the uniform algebraic rank are realized on ...
