Selected publications

Explicit Local Integrals of Motion for the Many-Body Localized State
L. Rademaker, M. Ortuno 
Phys. Rev. Lett. 116, 010404 (2016)
We provided a novel method to compute integrals of motion in a quantum system with interactions and disorder, based on ‘displacement transformations’. Unlike others, our method can also compute the integrals of motion in a delocalized system. Cited 152 times.

Enhanced superconductivity due to forward scattering in FeSe thin films on SrTiO3 substrates
L. Rademaker, Y. Wang, T. Berlijn and S. Johnston
New J. Phys. 18, 022001 (2016)
Our theory provides one of the most prominent explanations of enhanced superconductivity in single layer FeSe on STO substrates. It has inspired novel experiments (for example on the phonon linewidth) and lead to many theoretical discussions about the subtleties of two-dimensional superconductivity. Cited 128 times.

Impurity Bound States and Greens Function Zeroes as Local Signatures of Topology
R.-J. Slager, L. Rademaker, J. Zaanen and L. Balents
Phys. Rev. B 92, 085126 (2015)
The classification of topological phases of matter is of utmost importance in modern condensed matter physics. We provide a simple yet effective way of observing topology by means of the experimentally accessible local tunneling spectrum. Cited 167 times.

Charge-transfer insulation in twisted bilayer graphene
L. Rademaker, P. Mellado
Phys. Rev. B 98, 235158 (2018)
The discovery of superconductivity and Mott insulation in twisted bilayer graphene has inspired this work, where we show that the correlated insulator state stems from a macroscopic charge transfer between AA and AB regions of the Moiré unit cell. We were the first to point out the importance of real-space charge transfer. Cited 99 times.

Glassy dynamics in geometrically frustrated Coulomb liquids without disorder
S. Mahmoudian, L. Rademaker, A. Ralko, S. Fratini and V. Dobrosavljevic
Phys. Rev. Lett. 115, 025701 (2015)
Our theory has been experimentally confirmed in new experiments on organic electron glasses, and provides a new benchmark for glassy theories. At the moment, this work provides the dominant explanation for glassiness in the theta-organics. Cited 70 times.

Top experimental papers:

Hofstadter subband ferromagnetism and symmetry broken Chern insulators in twisted bilayer graphene
Y. Saito, J. Ge, L. Rademaker, K. Watanabe, T. Taniguchi, D. A. Abanin, A. F. Young
Nature Physics 17, 478 (2021)
Transport measurements of twisted bilayer graphene reveal a sequence of spin and valley polarized states with Chern numbers 1, 2, 3. We can understand these states using a Hartree theory on top of a Hofstadter butterfly. Cited 94 times.

Observation of flat bands in twisted bilayer graphene
S. Lisi et al.
Nature Physics 17, 189 (2021)
Using angle-resolved photo-emission spectroscopy we are the first to report a direct observation of the flat bands in twisted bilayer graphene. I calculated the matrix elements that determine how the flat bands are visible. Cited 86 times.
