Caring for a parent with pulmonary fibrosis in Malta: The lived experiences of daughters in mid-adulthood

Idiopathic pulmonary fibrosis is a progressive fibrotic lung disease that is on the rise globally. The disease is associated with significant morbidity and hence poses significant challenges for their informal carers, particularly daughters in mid-adulthood, who struggle with their own personal demands and that of their ill parents. Yet there is a dearth of literature on the experiences of these specific carers. Hence, the purpose of this study is to explore the lived experiences of daughters caring for a parent with pulmonary fibrosis within a community setting. This was explored using a phenomenological qualitative framework that was conducted between January and April 2017. Semi-structured audio-recorded interviews were conducted with six adult daughters who provided care to a parent having pulmonary fibrosis. Purposive sampling was used to recruit study participants. Transcribed data were analysed using Interpretative Phenomenological Analysis. Three main themes were extracted which communicate the essence of the daughters' lived experiences: "Walking on tiptoes", "Flooded by emotions" and "Shifts in family dynamics." Participants described experiencing the toll of being constantly vigilant for symptoms. They also expressed a range of emotions that included guilt, helplessness and worry related to their care experience. However, these emotional struggles were suppressed in order to present an external facade of strength and control. A shift in roles was also described where the daughters became the informal carers/support for both their ill and well parent, albeit in different ways. Caring for a person with pulmonary fibrosis is an emotional and life changing experience and hence, there is the need for individualised interventions that target the unique perceptions of these informal carers.

Fundamental Limits to Coherent Photon Generation with Solid-State Atomlike Transitions

Coherent generation of indistinguishable single photons is crucial for many quantum communication and processing protocols. Solid-state realizations of two-level atomic transitions or three-level spin-Λ systems offer significant advantages over their atomic counterparts for this purpose, albeit decoherence can arise due to environmental couplings. One popular approach to mitigate dephasing is to operate in the weak-excitation limit, where the excited-state population is minimal and coherently scattered photons dominate over incoherent emission. Here we probe the coherence of photons produced using two-level and spin-Λ solid-state systems. We observe that the coupling of the atomiclike transitions to the vibronic transitions of the crystal lattice is independent of the driving strength, even for detuned excitation using the spin-Λ configuration. We apply a polaron master equation to capture the non-Markovian dynamics of the vibrational manifolds. These results provide insight into the fundamental limitations to photon coherence from solid-state quantum emitters.
