Quantum Chaos in Time Series of Single Photons as a Superposition of Wave and Particle States

We build a time series of single photons with quantum chaos statistics, using a version of the Grangier anti-correlation experiment. The criteria utilized to determine the presence of quantum chaos is the frame of the Fano factor and the power spectrum. We also show that photons with chaotic statistics are in a balanced superposition of photons with both wave-like and particle like behaviors. To support the presence of quantum chaos, we study both Shannon’s entropy, and the complexity of single photons time series.

Null Objects in Korean: Experimental Evidence for the Argument Ellipsis Analysis

Null object (NO) constructions in Korean and Japanese have received different accounts: as (a) argument ellipsis ( Oku 1998 , S. Kim 1999 , Saito 2007 , Sakamoto 2015 ), (b) VP-ellipsis after verb raising ( Otani and Whitman 1991 , Funakoshi 2016 ), or (c) instances of base-generated pro ( Park 1997 , Hoji 1998 , 2003 ). We report results from two experiments supporting the argument ellipsis analysis for Korean. Experiment 1 builds on K.-M. Kim and Han’s (2016) finding of interspeaker variation in whether the pronoun ku can be bound by a quantifier. Results showed that a speaker’s acceptance of quantifier-bound ku positively correlates with acceptance of sloppy readings in NO sentences. We argue that an ellipsis account, in which the NO site contains internal structure hosting the pronoun, accounts for this correlation. Experiment 2, testing the recovery of adverbials in NO sentences, showed that only the object (not the adverb) can be recovered in the NO site, excluding the possibility of VP-ellipsis. Taken together, our findings suggest that NOs result from argument ellipsis in Korean.

Multi-exciton emission from solitary dopant states of carbon nanotubes

By separating the photons from slow and fast decays of single- and multi-excitons in a time gated 2nd order photon correlation experiment, we show that solitary oxygen dopants of carbon nanotubes allow emission of photon pairs with ∼44% of single exciton quantum yield.
