Quantum light-driven strong-field physics at metallic needle tips – new publication in Nature Physics
Strong-field phenomena in the interaction of light and matter have been studied extensively in recent years and decades. Typically, however, almost all experiments in this field had one feature in common: they used intense classical laser light, i.e., a coherent state of light, as the driver of strong-field physics.
But what happens if we instead use intense quantum light such as BSV (“bright squeezed vacuum”) to drive strong-field physics at the surface of metallic needle tips? We explore this question in our latest publication [1], which was recently released at Nature Physics. Further information can also be found in the accompanying press release [2] and in an informative overview article [3] that was published together with our article.
