Ultrafast energy relaxation of quantum dot-generated 2D hot electrons
Dongsung T. Park, Dongkun Kim, Uhjin Kim +8
Through a series of transverse magnetic focusing experiments, we show that hot electrons in a two-dimensional electron gas system undergo an ultrafast relaxation when generated by…
Negative Excess Shot Noise by Anyon Braiding
Byeongmok Lee, Cheolhee Han, H. -S. Sim
Anyonic fractional charges have been detected by autocorrelation shot noise at a quantum point contact (QPC) between two fractional quantum Hall edges. We find that the autoc…
Non-Abelian Evolution of a Majorana Train in a Single Josephson Junction
Sang-Jun Choi, H. -S. Sim
Demonstration of non-Abelian anyon statistics often requires dynamical controls of a complicated device that are challenging in realistic situations. We propose a {\it single} Jose…
Detailed Balance of Thermalization dynamics in Rydberg atom quantum simulators
Hyosub Kim, Yeje Park, Kyungtae Kim +2
Dynamics of large complex systems, such as relaxation towards equilibrium in classical statistical mechanics, often obeys a master equation. The equation significantly simplifies t…
Topological vacuum bubble by anyon braiding
Cheolhee Han, Jinhong Park, Yuval Gefen +1
According to a basic rule of fermionic and bosonic many-body physics, known as the linked cluster theorem, physical observables are not affected by vacuum bubbles, which represent…
Phonon emission and arrival times of electrons from a single-electron source
C. Emary, A. Dyson, Sungguen Ryu +2
In recent charge-pump experiments, single electrons are injected into quantum Hall edge channels at energies significantly above the Fermi level. We consider here the relaxation of…
