We review recent theoretical work on two closely related issues: excitation of an isolated quantum condensed matter system driven adiabatically across a continuous quantum phase transition or a gapless phase, and apparent relaxation of an excited system after a sudden quench of a parameter in its Hamiltonian. Accordingly the review is divided into two parts. The first part revolves around a quantum version of the Kibble-Zurek mechanism including also phenomena that go beyond this simple paradigm. What they have in common is that excitation of a gapless many-body system scales with a power of the driving rate. The second part attempts a systematic presentation of recent results and conjectures on apparent relaxation of a pure state of an isolated quantum many-body system after its excitation by a sudden quench. This research is motivated in part by recent experimental developments in the physics of ultracold atoms with potential applications in the adiabatic quantum state preparation and quantum computation.

“…Many of the dematiaceous fungi are resistant to antifungal therapy; further complicating the management of affected patients. The dematiaceous fungus P. richardsiae has rarely been implicated in human disease but has been described in one case of exogenous endophthalmitis following trauma with a retained intraocular foreign body [14]. …”

“…This may be due to the long interval between the trauma and development of symptoms and therefore patients may not remember the inciting injury [13, 16]. Rare cases of endocarditis of a porcine mitral valve, dacryocystitis, and exogenous endophthalmitis have also been reported [3, 13, 14]. Similar to other dematiaceous fungi, many cases of P. richardsiae infection involve patients who are immunocompromised or immunosuppressed; however, multiple cases have been described in immunocompetent patients [13, 16, 17].…”

Background Pleurostomophora richardsiae (formerly Phialophora richardsiae) is a dematiaceous fungus that is an uncommon cause of ocular infection. Herein, we present a case of endogenous endophthalmitis associated with disseminated P. richardsiae infection.FindingsThis is a descriptive case report with a brief review of literature. A 43-year-old male admitted to the hospital following an acute cerebellar hemorrhage was found to have a swollen and tender wrist. The patient was afebrile with leukocytosis. Visual acuity was hand motion in the right eye and 20/20 in the left. Right eye examination noted anterior chamber cells and flare, vitreous haze and multiple large, and fluffy retinal infiltrates. Diagnostic vitrectomy revealed a mixed inflammatory cell infiltrate with numerous fungal elements. Blood cultures were negative, multiple transesophageal echocardiography studies revealed no vegetations, and synovial fluid aspiration of the wrist and biopsy of the radius were unremarkable. The patient was treated with intravitreal cefazolin, vancomycin, and amphotericin B, topical ciprofloxacin and natamycin, and intravenous amphotericin B and voriconazole. Visual acuity in the right eye declined to light perception, and examination revealed increasing anterior and posterior chamber inflammation. The patient died several weeks after presentation due to a massive intracranial hemorrhage. Fungal culture results from the vitrectomy were received post mortem and were positive for P. richardsiae.Conclusions P. richardsiae endophthalmitis is rare, and outcomes are typically poor. Infections typically occur following traumatic skin inoculation; however, a long refractory period may occur before symptoms develop. Early diagnosis and combination antimicrobial therapy are essential to optimize visual outcomes.

A 20-year-old man developed increasing inflammation with a hypopyon 3 weeks after primary repair of a corneal laceration. An occult anterior capsule puncture was suspected as the stimulus for the inflammation. When aspiration of the suspected hydrated lens material was not curative, a vitrectomy with injection of intravitreal antibiotic agents including amphotericin (0.0125 mg) was done the following day; the culture failed to grow fungal organisms. A repeat vitrectomy was performed 1 week later, and the culture grew Aspergillus terreus. This was determined to be resistant to amphotericin so voriconazole was injected intravitreally. The inflammation recurred, and the eye required enucleation because of blindness and intractable pain. Fungal endophthalmitis should be considered in cases of delayed-onset inflammation after trauma and may be due to organisms resistant to amphotericin.
