Experimental Study of the Exciton Gas Liquid Transition in Coupled Quantum Wells
Subhradeep Misra, Michael Stern, Arjun Joshua +2
We study the exciton gas-liquid transition in GaAs/AlGaAs coupled quantum wells. Below a critical temperature, Tc=4.8K, and above a threshold laser power density the system undergo…
Local Electrostatic Imaging of Striped Domain Order in LaAlO3/SrTiO3
Maayan Honig, Joseph A. Sulpizio, Jonathan Drori +3
The emerging field of complex oxide interfaces is generically built on one of the most celebrated substrates - strontium titanate (SrTiO3). This material hosts a range of phenomena…
Competition Between Kondo Screening and Magnetism at the LaAlO/SrTiO Interface
Jonathan Ruhman, Arjun Joshua, Shahal Ilani +1
We present a theory of magnetic and magneto-transport phenomena at LaAlO/SrTiO interfaces, which as a central ingredient includes coupling between the conduction bands and…
A Gate-tunable Polarized Phase of Two-Dimensional Electrons at the LaAlO3/SrTiO3 Interface
Arjun Joshua, J. Ruhman, S. Pecker +2
Controlling the coupling between localized spins and itinerant electrons can lead to exotic magnetic states. A novel system featuring local magnetic moments and extended 2D electro…
A Universal Critical Density Underlying the Physics of Electrons at the LaAlO3/SrTiO3 Interface
Arjun Joshua, S. Pecker, J. Ruhman +2
The two-dimensional electron system formed at the interface between the insulating oxides LaAlO3 and SrTiO3 exhibits ferromagnetism, superconductivity, and a wide range of unique m…
Quasi-equilibrium optical nonlinearities in spin-polarized GaAs
Arjun Joshua, V. Venkataraman
Semiconductor Bloch equations, which microscopically describe the dynamics of a Coulomb interacting, spin-unpolarized electron-hole plasma, can be solved in two limits: the coheren…
