Faddeev-Jackiw quantization of topological invariants: Euler and Pontryagin classes
, 2017 The symplectic analysis for the four dimensional Pontryagin and Euler invariants is performed within the Faddeev-Jackiw context. The Faddeev-Jackiw constraints and the generalized Faddeev-Jackiw brackets are reported; we show that in spite of the ...

Scalar mesons as simple quark+antiquark states [PDF]
AIP Conf. Proc. 508 (1999) 310-317, Hadron Physics, Sept. 1999,
Coimbra, Portugal, 1999 The Nijmegen Unitarized Meson Model and its application to scalar mesons is briefly revisited. It is shown that all scalar states up to 1.5 GeV can be described as triplet-P-zero quark+antiquark states coupled to the OZI-allowed open and closed two-meson channels consisting of pseudoscalar and vector mesons. Crucial are the manifestation of a resonance-

Quantum Games in Open Systems using Biophysic Hamiltonians [PDF]
, 2006 We analyze the necessary physical conditions to model an open quantum system as a quantum game. By applying the formalism of Quantum Operations on a particular system, we use Kraus operators as quantum strategies. The physical interpretation is a conflict among different configurations of the environment. The resolution of the conflict displays regimes

In Situ Light‐Modulation of Capacity and Impedance in Lithium‐Ion Batteries
Advanced Science, EarlyView.This study introduces a dynamic light‐controlled modulation (DLCM) anode for LIBs using CdS alignments and light‐sensitive graphene, effective across UV to visible light. The developed DLCM anode exhibits a remarkable maximum capacity of 430 mAh g−1 when subjected to UV light illumination, surpassing the capacity observed in the absence of illumination,

Is a quantum theory of resonances really time asymmetric? [PDF]
arXiv, 2003 The title "Time Asymmetric Quantum Theory: the Theory of Resonances" (without questionmark) of the CFIF workshop (23.-26.7.2003, Lisbon, Portugal) implies that the theoretical description of resonances is uniquely described by the formalism of A. Bohm et al. reflecting the title of the workshop.
