Engineering stacking-induced topological phase transitions in bilayer heterostructures
Arjyama Bordoloi, Daniel Kaplan, Sobhit Singh
Nonmagnetic topological insulators (TIs) are known for their robust metallic surface/edge states that are protected by time-reversal symmetry, making them promising candidates for…

Tunable Spatiotemporal Orders in Driven Insulators
Daniel Kaplan, Pavel A. Volkov, Ahana Chakraborty +2
We show that driving optical phonons above a threshold fluence induces spatiotemporal orders, where material properties oscillate at an incommensurate wavevector in space and…
