Concealed Mott Criticality: Unifying the Kondo Breakdown and Doped Charge-Transfer Insulators
Louk Rademaker
I show that the quantum critical points observed in heavy fermions (the `Kondo breakdown') and in doped cuprates can be understood in terms of concealed Mott criticality. In this p…
The Instability of a Quantum Superposition of Time Dilations
Louk Rademaker, Tom van der Reep, Nick Van den Broeck +3
Using the relativistic concept of time dilation we show that a superposition of gravitational potentials can lead to nonunitary time evolution. For sufficiently weak gravitational…
Moire magnetism in CrBr3 multilayers emerging from differential strain
Fengrui Yao, Dario Rossi, Ivo A. Gabrovski +8
Interfaces between twisted 2D materials host a wealth of physical phenomena originating from the long-scale periodicity associated with the resulting moire structure. Besides twist…
Pressure-tuned many-body phases through -K valleytronics in moiré bilayer WSe
Marta BrzeziÅska, Sergii Grytsiuk, Malte Rösner +2
Recent experiments in twisted bilayer transition-metal dichalcogenides have revealed a variety of strongly correlated phenomena. To theoretically explore their origin, we combine h…
