Photoexcitation Cascade and Quantum-Relativistic Jets in Graphene
Cyprian Lewandowski, L. S. Levitov
In Dirac materials linear band dispersion blocks momentum-conserving interband transitions, creating a bottleneck for electron-hole pair production and carrier multiplication in th…
Soft pair excitations and double-log divergences due to carrier interactions in graphene
Cyprian Lewandowski, L. S. Levitov
Interactions between charge carriers in graphene lead to logarithmic renormalization of observables mimicking the behavior known in (3+1)-dimensional quantum electrodynamics (QED).…
Self-sustaining dynamical nuclear polarization oscillations in quantum dots
M. S. Rudner, L. S. Levitov
Early experiments on spin-blockaded double quantum dots revealed surprising robust, large-amplitude current oscillations in the presence of a static (dc) source-drain bias [see e.g…
Phase-Sensitive Probes of Nuclear Polarization in Spin-Blockaded Transport
M. S. Rudner, I. Neder, L. S. Levitov +1
Spin-blockaded quantum dots provide a unique setting for studying nuclear-spin dynamics in a nanoscale system. Despite recent experimental progress, observing phase-sensitive pheno…
Atomic Collapse and Quasi-Rydberg States in Graphene
A. V. Shytov, M. I. Katsnelson, L. S. Levitov
Charge impurities in graphene can host an infinite family of Rydberg-like resonance states of massless Dirac particles. These states, appearing for supercritical charge, are descri…
Vacuum Polarization and Screening of Supercritical Impurities in Graphene
A. V. Shytov, M. I. Katsnelson, L. S. Levitov
Screening of charge impurities in graphene is analyzed using the exact solution for vacuum polarization obtained from the massless Dirac-Kepler problem. For the impurity charge bel…
