Collective excitations of exciton-polariton condensates in a synthetic gauge field
D. Biegańska, M. Pieczarka, E. Estrecho +7
Collective (elementary) excitations of quantum bosonic condensates, including condensates of exciton polaritons in semiconductor microcavities, are a sensitive probe of interpartic…
Observation of Spontaneous Ferromagnetism in a Two-Dimensional Electron System
Md. S. Hossain, M. K. Ma, K. A. Villegas Rosales +5
What are the ground states of an interacting, low-density electron system? In the absence of disorder, it has long been expected that as the electron density is lowered, the exchan…
Bloch Ferromagnetism of Composite Fermions
Md. Shafayat Hossain, Tongzhou Zhao, Songyang Pu +9
In 1929 Felix Bloch suggested that the paramagnetic Fermi sea of electrons should make a spontaneous transition to a fully-magnetized state at very low densities, because the excha…
Edge State Wave Functions from Momentum-Conserving Tunneling Spectroscopy
T. Patlatiuk, C. P. Scheller, D. Hill +7
We perform momentum-conserving tunneling spectroscopy using a GaAs cleaved-edge overgrowth quantum wire to investigate adjacent quantum Hall edge states. We use the lowest five wir…
Observation of Algebraic Time Order for Two-Dimensional Dipolar Excitons
S. Dang, M. Zamorano, S. Suffit +5
Emergence of algebraic quasi-long-range order is a key feature of superfluid phase transitions at two dimensions. For this reduced dimensionality interactions prevent Bose-Einstein…
