Designing the Self‐Assembly of Disordered Materials Via Color Frustration
Advanced Materials, EarlyView.What if disorder can be designed? This work introduces a strategy to self‐assemble amorphous materials by designing bonding rules for patchy particles that suppress crystallinity and promote frustration. The designer particles nucleate a network of dodecahedral cages from the liquid, yielding a novel equilibrium amorphous phase. This approach redefines

The dynamics of the relativistic Kepler problem
Results in Physics, 2020 We deal with the Hamiltonian system (HS) associated to the Hamiltonian in polar coordinates H=12pr2+pϕ2r2-1r-∊2r2, where ∊ is a small parameter. This Hamiltonain comes from the correction given by the special relativity to the motion of the two-body ...

On periodic differential equations with dissipation
Electronic Journal of Qualitative Theory of Differential Equations, 2018 In this work we present an unexpected relation between the discriminant associated to a Hill equation with and without dissipation. We prove that by knowing the discriminant associated to a periodic differential equation, which is the summation of the ...

Preparing Magnon–Photon Pairs in a Cavity–Magnon–Qubit System
Advanced Photonics Research, EarlyView.By utilizing the photon blockade effect, hybrid magnon–photon quantum states are prepared in a cavity–magnon–qubit system. Through the analysis of correlation functions, the generated magnon–photon pairs are shown to exhibit high purity and strong correlations.

Homoclinic solutions for second order Hamiltonian systems with general potentials near the origin
Electronic Journal of Qualitative Theory of Differential Equations, 2013 In this paper, we study the existence of infinitely many homoclinic solutions for a class of second order Hamiltonian systems with general potentials near the origin. Recent results from the literature are generalized and significantly improved.
