Probing Impurity Quantum Criticality with Entanglement Witnesses
Mateo Cárdenes Wuttig, Andrew J. Millis
Entanglement is a defining feature of quantum mechanics, and its relation to quantum criticality is of considerable current interest. Here we show that measurable spin and charge f…

High-field Josephson effect enabled by a moiré Hofstadter spectrum
A. DÃez-Carlón, M. Cárdenes Wuttig, N. Wei +7
The paper demonstrates that graphene/hBN Josephson junctions engineered with a moiré superlattice can maintain phase‑coherent superconducting transport at magnetic fields up to 6 T…

From One to Two Dimensions: Magnetic Phases in Weakly Coupled Spin Ladders
Mateo Cárdenes Wuttig, Andrew J. Millis
A large variety of materials can be approximately described by means of spin-1/2 Heisenberg ladders. Here, the Density Matrix Renormalization Group (DMRG) algorithm together with a…
