Laser-Polarization Dependence of Betatron X-Ray Production and Angular Collection in Laser-Wakefield Acceleration
Andrei Ciprian Berceanu, Vojtěch Horný, Dan Stutman +1
Laser polarization affects both the production of betatron x rays and their angular distribution, which together determine the photon yield collected within a fixed angular accepta…
Quantized Transport of Gap Solitons in the Harper-Hofstadter Model
Oliver Ashfield, Henry Davenport, Tom Sheppard +6
We investigate the dynamics of gap solitons found in the Harper-Hofstadter model with an additional cubic nonlinearity, such as that describing weakly-interacting cold atoms or a K…
Momentum-space Landau levels in driven-dissipative cavity arrays
Andrei C. Berceanu, Hannah M. Price, Tomoki Ozawa +1
We theoretically study the driven-dissipative Harper-Hofstadter model on a 2D square lattice in the presence of a weak harmonic trap. Without pumping and loss, the eigenstates of t…
On multicomponent polariton superfluidity in the optical parametric oscillator regime
A. C. Berceanu, L. Dominici, I. Carusotto +6
Superfluidity, the ability of a liquid or gas to flow with zero viscosity, is one of the most remarkable implications of collective quantum coherence. In equilibrium systems like l…
Drag in a resonantly driven polariton fluid
A. Berceanu, E. Cancellieri, F. M. Marchetti
We study the linear response of a coherently driven polariton fluid in the pump-only configuration scattering against a point-like defect and evaluate analytically the drag force e…
Onset and dynamics of vortex-antivortex pairs in polariton OPO superfluids
G. Tosi, F. M. Marchetti, D. Sanvitto +8
We study, both theoretically and experimentally, the occurrence of topological defects in polariton superfluids in the optical parametric oscillator (OPO) regime. We explain in ter…
Pseudodiffusive transmission of nodal Dirac fermions through a clean d-wave superconductor
J. K. Asboth, A. R. Akhmerov, A. C. Berceanu +1
We calculate the transmission of electrons and holes between two normal-metal electrodes (N), separated over a distance L by an impurity-free superconductor (S) with d-wave symmetr…
