Electrical Spectroscopy of Polaritonic Nanoresonators
Sebastián Castilla, Hitesh Agarwal, Ioannis Vangelidis +13
One of the most captivating properties of polaritons is their capacity to confine light at the nanoscale. This confinement is even more extreme in two-dimensional (2D) materials. 2…
Recognizing molecular chirality via twisted 2D materials
Lorenzo Cavicchi, Mayra Peralta, Álvaro Moreno +6
Chirality pervades natural processes from the atomic to the cosmic scales, crucially impacting molecular chemistry and pharmaceutics. Traditional chirality sensing methods face cha…
Twisted bilayer graphene for enantiomeric sensing of chiral molecules
Álvaro Moreno, Lorenzo Cavicchi, Xia Wang +8
Selective sensing of chiral molecules is a key aspect in fields spanning biology, chemistry, and pharmacology. However, conventional optical methods, such as circular dichroism (CD…
Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underlyi…
Infrared Spectroscopy for Diagnosing Superlattice Minibands in Magic-angle Twisted Bilayer Graphene
Geng Li, Roshan Krishna Kumar, Petr Stepanov +11
Twisted bilayer graphene (TBG) represents a highly tunable, strongly correlated electron system owed to its unique flat electronic bands. However, understanding the single-particle…
