In doing so, we reveal that perturbations to the Lugiato-Lefever equation that maintain reversibility, such as fourth order dispersion, lead to bound states that tend to separate from one another in time when n
Formation of Bound StatesOne of the distinctive characteristics of quantum mechanics, in contrast to classical mechanics, is the existence of bound states corresponding to discrete energy levels. Some of the conditions under which this happens will be discussed in this chapter....
we observe an unexpected resilience of the bound states to integrability breaking. This finding goes against the idea that bound states in non-integrable systems are unstable when their energies overlap with the continuum spectrum. Our work provides...
In QPCs with a highly asymmetric geometry, we observe sharp resonance peaks when the point contacts are gated to the single mode regime, and surprisingly, under certain gating conditions, a complete destruction of the 2e/h first quantum plateau. The temperature evolution of the resonances suggest...
We investigate the appearance of cusp structures in single-particle momentum distributions for processes leading to three-body continuum states. We discuss under which circumstances these structures are produced, and identify some of their properties by means of a final-state interaction theory. Finally...
Defect formation energies can be used to evaluate thermodynamic transition levels (CTL) defined as the Fermi-level position for which the formation energies of charge states q1 and q2 are equal. From: Microelectronics Reliability, 2018 About this pageSet alert ...
In the resulting vacuum, the usual relation between the gauge couplings and the Higgs self-coupling does not apply, and there is no reason to expect the same upper bound on the mass of the lightest Higgs boson. In a simple model where the bound state is assumed to have no mixing with ...
in details. We applied continuum elasticity theory to obtain continuous trajectory of pore formation and closure, and analyzed molecular dynamics trajectories of pre-formed pore reseal. We hypothesized that a transversal pore is preceded by a hydrophobic defect: intermediate structure spanning through the...
may have some relevance for understanding aspects of change between the early and mid-fourth millennium BC. In the literature on Predynastic Egypt, the concept of “chiefdoms” remains a resilient feature, albeit one frequently rebranded as “proto-states,”“proto-nomes,” or “proto-kingdoms....
“The earlier investigators believed that humus formation takes place in nature by a specific process of ‘humification’ whereby the plant residues are bodily transformed into dark colored substances, or humus” (Waksman, 1936). It is obvious that research into the existence of biotic or abiotic ...
