Chiral Rashba spin textures in ultra-cold Fermi gases
Jay D. Sau, Rajdeep Sensarma, Stephen Powell +2
Spin-orbit coupling is an important ingredient in many recently discovered phenomena such as the spin-Hall effect and topological insulators. Of particular interest is topological…
Bogoliubov theory of interacting bosons on a lattice in a synthetic magnetic field
Stephen Powell, Ryan Barnett, Rajdeep Sensarma +1
We consider theoretically the problem of an artificial gauge potential applied to a cold atomic system of interacting neutral bosons in a tight-binding optical lattice. Using the B…
Plasmon-phonon coupling in graphene
E. H. Hwang, Rajdeep Sensarma, S. Das Sarma
Collective excitations of coupled electron-phonon systems are calculated for both monolayer and bilayer graphene, taking into account the non-perturbative Coulomb coupling between…
Gutzwiller-projected wave functions for the pseudogap state of underdoped high-temperature superconductors
Rajdeep Sensarma, Victor Galitski
Recent experiments strongly suggest that a Fermi surface reconstruction and multiple Fermi pockets are important common features of the underdoped high-temperature cuprate supercon…
Dynamic Screening and Low Energy Collective Modes in Bilayer Graphene
Rajdeep Sensarma, E. H. Hwang, S. Das Sarma
We theoretically study the dynamic screening properties of bilayer graphene within the random phase approximation assuming quadratic band dispersion and zero gap for the single-par…
Competition between pairing and ferromagnetic instabilities in ultracold Fermi gases near Feshbach resonances
David Pekker, Mehrtash Babadi, Rajdeep Sensarma +4
We study the quench dynamics of a two-component ultracold Fermi gas from the weak into the strong interaction regime, where the short time dynamics are governed by the exponential…
