Artificial trapping of a stable high-density dipolar exciton fluid
Gang Chen, Ronen Rapaport, L. N. Pffeifer +5
We present compelling experimental evidence for a successful electrostatic trapping of two-dimensional dipolar excitons that results in stable formation of a well confined, high-de…
Moving Beyond a Simple Model of Luminescence Rings in Quantum Well Structures
D. Snoke, S. Denev, Y. Liu +5
The dramatic appearance of luminescence rings with radius of several hundred microns in quantum well structures can be understood through a fairly simple nonlinear model of the dif…
Chiral modes at exceptional points in exciton-polariton quantum fluids
T. Gao, G. Li, E. Estrecho +10
We demonstrate generation of chiral modes -- vortex flows with fixed handedness in exciton-polariton quantum fluids. The chiral modes arise in the vicinity of exceptional points (n…
The Basis of the Second Law of Thermodynamics in Quantum Field Theory
D. Snoke, G. Liu, S. Girvin
The result that closed systems evolve toward equilibrium is derived entirely on the basis of quantum field theory for a model system, without invoking any of the common extra-mathe…
Mechanism of Luminescence Ring Pattern Formation in Quantum Well Structures: Optically-Induced In-Plane Charge Separation
R. Rapaport, Gang Chen, D. Snoke +6
About a year ago, two independent experiments [1,2], imaging indirect exciton luminescence from doped double quantum wells under applied bias and optical excitation, reported a ver…
