This research investigates cavity engineering with atomically thin materials to manipulate vacuum fluctuations and alter light-matter interactions in twisted trilayer graphene. By treating the quantum vacuum as a dynamic medium rather than empty space, the study advances fundamental understanding of how energy and time are borrowed from transient quantum objects. This work represents a significant step forward in controlling quantum phenomena through engineered environments.

Columbia grad student explains ‘fizzy’ quantum vacuum

Quantum ZeitgeistSeptember 24, 20265 min read

Columbia grad student Lucia Rondini explores how seemingly empty space is actually ‘fizzy’ with fleeting quantum objects, impacting light-matter interactions.

Lucia Rondini, a Columbia University physics graduate student, describes the vacuum of space not as emptiness, but as “fizzy” with quantum objects constantly appearing and disappearing. Rondini’s research, conducted with James McIver, who joined Columbia in 2022 as part of a six-institution collaboration including Columbia University, the Flatiron Institute, the Max Planck Institutes for the Structure and Dynamics of Matter (MPSD) in Hamburg and Polymer Research in Mainz, Germany, and Cornell University in Ithaca, New York, uses a technique called cavity engineering with atomically thin materials to explore these fleeting phenomena. McIver’s lab investigates how light interacts with materials, and is now studying how…
