Nontrivial low-frequency topological waves at the boundary of a magnetized plasma
Roopendra Singh Rajawat, Tianhong Wang, Gennady Shvets
The topological properties of a magnetized cold gaseous plasma have recently been explored and the existence of topologically protected edge states has been established. These stud…
Positron Acceleration in an Elongated Bubble Regime
Tianhong Wang, Vladimir Khudik, Gennady Shvets
A new concept is proposed for accelerating positrons in a nonlinear plasma wakefield accelerator. By loading the wakefield (back of the plasma bubble) with a short electron bunch,…
Sub-femtosecond wakefield injector and accelerator based on an undulating plasma bubble controlled by a laser phase
Jihoon Kim, Tianhong Wang, Vladimir Khudik +1
We demonstrate that a long-propagating plasma bubble executing undulatory motion can be produced in the wake of two co-propagating laser pulses: a near-single-cycle injector and a…
WAND-PIC: an accelerated three-dimensional quasi-static particle-in-cell code
Tianhong Wang, Vladimir Khudik, Jihoon Kim +1
We introduce a quasi-static particle-in-cell (PIC) code -- WAND-PIC -- which does not suffer from some of the common limitations of many quasi-static PICs, such as the need for a p…
Laser-Pulse and Electron-Bunch Plasma Wakefield Accelerator
Tianhong Wang, Vladimir Khudik, Gennady Shvets
Propagation distances of intense laser pulses and high-charge electron beams through the plasma are, respectively, limited by diffraction and self-deceleration. This imposes severe…
Laser-Ion Lens and Accelerator
Tianhong Wang, Vladimir Khudik, Gennady Shvets
Generation of highly collimated monoenergetic relativistic ion beams is one of the most challenging and promising areas in ultra-intense laser-matter interactions because of the nu…
Direct laser acceleration of electrons by tightly focused laser pulses
Tianhong Wang, Vladimir Khudik, Alexey Arefiev +1
We present an analytical theory that reveals the importance of the longitudinal laser electric field in the resonant acceleration of relativistic electrons by the tightly confined…
Nonlinear plasma waves driven by short ultrarelativistic electron bunches
Tianhong Wang, Vladimir Khudik, Boris Breizman +1
We advance a theory of quasistatic approximation and investigate the excitation of nonlinear plasma waves by the driving beam of ultrarelativistic electrons using novel electrostat…
Far-field constant-gradient laser accelerator of electrons in an ion channel
Vladimir Khudik, Xi Zhang, Gennady Shvets
We predict that electrons in an ion channel can gain ultra-relativistic energies by simultaneously interacting with a laser pulse and, counter-intuitively, with a decelerating elec…
