Squeezing Quantum States in Three-Dimensional Twisted Crystals
Vo Tien Phong, Kason Kunkelmann, Christophe De Beule +4
A fundamental idea in wave mechanics is that propagation in a periodic medium can be described by Bloch waves whose conserved crystal momenta define their transformations when disp…
Elastic Screening of Pseudogauge Fields in Graphene
Christophe De Beule, Robin Smeyers, Wilson Nieto Luna +2
Lattice deformations in graphene couple to the low-energy electronic degrees of freedom as effective scalar and gauge fields. Using molecular dynamics simulations, we show that the…
Floquet-Bloch Theory for Nonperturbative Response to a Static Drive
Christophe De Beule, Steven Gassner, Spenser Talkington +1
We develop the Floquet-Bloch theory of noninteracting fermions on a periodic lattice in the presence of a constant electric field. As long as the field lies along a reciprocal latt…
Analytical Model for Atomic Relaxation in Twisted Moiré Materials
Mohammed M. Al Ezzi, Gayani N. Pallewela, Christophe De Beule +2
By virtue of being atomically thin, the electronic properties of heterostructures built from two-dimensional materials are strongly influenced by atomic relaxation. The atomic laye…
