Non-Hermitian spectral degeneracies, known as exceptional points (EPs), feature simultaneous coalescence of both eigenvalues and the associated eigenstates a system. A host intriguing EP effects their applications have been revealed in classical realm, such loss-induced lasing, single-mode laser, EP-enhanced sensing. Here we show that purely quantum effect, single-photon blockade, emerges Kerr ...

This paper presents a detailed analysis of the so-called proleptic accusative. This construction type is rare, but attested in a number of different languages. Here, we discuss data from Middle Dutch in particular, which enables us to shed new light on the matter. We show that the proleptic accusative is crucially different from complex cases of raising. Instead, we explore two novel and compet...
