We propose magic-angle helical trilayer graphene (HTG), a helical structure featuring
identical rotation angles between three consecutive layers of graphene, as a unique and …

Moiré systems have emerged in recent years as a rich platform to study strong correlations.
Here, we will propose a simple, experimentally feasible setup based on periodically strained …

We study flat bands and their topology in 2D materials with quadratic band crossing points
under periodic strain. In contrast to Dirac points in graphene, where strain acts as a vector …

The discovery of correlated phases in twisted moiré superlattices accelerated the search for
low-dimensional materials with exotic properties. A promising approach uses engineered …

In two-dimensional artificial crystals with large real-space periodicity, the nonlinear current
response to a large applied electric field can feature a strong angular dependence, which …

Valley chiral kagome networks can arise in various situations like, for example, in double-
aligned graphene-hexagonal boron nitride and periodically strained graphene. Here, we …

The rise of straintronics—the possibility of fine-tuning the electronic properties of
nanosystems by applying strain to them—has enhanced the interest in characterizing the …

Lattice deformations in graphene couple to the low-energy electronic degrees of freedom as
pseudo scalar and gauge fields. Using molecular dynamics simulations, we show that the …

It is well-known that macroscopically-normalizable zero-energy wavefunctions of spin-$\frac
{1}{2} $ particles in a two-dimensional inhomogeneous magnetic field are spin-polarized …

In this thesis, we study the quantum properties of semimetallic few-layer graphene, and its
van der Waals (vdW) heterostructures with insulating hexagonal boron nitride (hBN) and the …
