Nonperturbative potentials: Phase transitions and light horizons
Yuan Shi
It is commonly believed that a massive real scalar field only mediates short-range interactions on the scale of its Compton wavelength via the Yukawa potential. However, in the…
Plasma physics in strong-field regimes: theories and simulations
Yuan Shi, Hong Qin, Nathaniel J. Fisch
In strong electromagnetic fields, unique plasma phenomena and applications emerge, whose description requires recently developed theories and simulations [Y. Shi, Ph.D. thesis, Pri…
Simulating nonnative cubic interactions on noisy quantum machines
Yuan Shi, Alessandro R. Castelli, Xian Wu +8
As a milestone for general-purpose computing machines, we demonstrate that quantum processors can be programmed to efficiently simulate dynamics that are not native to the hardware…
Force, metric, or mass: Disambiguating causes of uniform gravity
Yuan Shi
In addition to nonzero forces and nontrivial metrics, here I show that a nonconstant Higgs expectation value, which endows elementary particles with their masses, also leads to app…
Amplification of mid-infrared lasers via magnetized-plasma coupling
Yuan Shi, Nathaniel J. Fisch
Plasmas may be used as gain media for amplifying intense lasers, and external magnetic fields may be applied to improve the performance. For mid-infrared lasers, the requisite magn…
Three-wave interactions in magnetized warm-fluid plasmas: general theory with evaluable coupling coefficient
Yuan Shi
Resonant three-wave coupling is an important mechanism via which waves interact in a nonlinear medium. When the medium is a magnetized warm-fluid plasma, a previously-unknown formu…
Do pulsars rotate clockwise or counterclockwise?
Renaud Gueroult, Yuan Shi, Jean-Marcel Rax +1
Pulsars are rotating neutron stars which emit lighthouse-like beams. Owing to their unique properties, pulsars are a unique astrophysical tool to test general relativity, inform on…
Radiation reaction of classical hyperbolic oscillator: experimental signatures
Yuan Shi
When accelerated by a constant force in the lab frame, a classical charge experiences no self force. In this case, the particle radiates without dissipating its kinetic and potenti…
Laser Amplification in Strongly-Magnetized Plasma
Matthew R. Edwards, Yuan Shi, Julia M. Mikhailova +1
We consider backscattering of laser pulses in strongly-magnetized plasma mediated by kinetic magnetohydrodynamic waves. Magnetized low-frequency scattering, which can occur when th…
Controlling azimuthal spoke modes in cylindrical Hall thruster using a segmented anode
Yuan Shi, Yevgeny Raitses
Azimuthal spoke-like modes commonly occur in ExB discharges. The natural occurrence of the spoke mode is correlated with changes of plasma parameters. Here, instead of allowing the…
Plasma Physics in Strong Field Regimes
Yuan Shi
In strong electromagnetic fields, new plasma phenomena and applications emerge, whose modeling requires analytical theories and numerical schemes that I will develop in this thesis…
Simulations of relativistic-quantum plasmas using real-time lattice scalar QED
Yuan Shi, Jianyuan Xiao, Hong Qin +1
Real-time lattice quantum electrodynamics (QED) provides a unique tool for simulating plasmas in the strong-field regime, where collective plasma scales are not well-separated from…
On the physical mechanism of three-wave instabilities -- resonance between positive- and negative-action modes
Ruili Zhang, Hong Qin, Yuan Shi +2
Three-wave instability is a fundamental process that has important applications in many branches of physics. It is widely accepted that the resonant condition $ω_{z}\approxω_{x}+ω_…
Laser-plasma interaction in magnetized environment
Yuan Shi, Hong Qin, Nathaniel J. Fisch
Propagation and scattering of lasers present new phenomena and applications when the plasma medium becomes strongly magnetized. With mega-Gauss magnetic fields, scattering of optic…
Three-wave scattering in magnetized plasmas: from cold fluid to quantized Lagrangian
Yuan Shi, Hong Qin, Nathaniel J. Fisch
Large amplitude waves in magnetized plasmas, generated either by external pumps or internal instabilities, can scatter via three-waves interactions. While three-wave scatterings in…
Laser Pulse Compression Using Magnetized Plasmas
Yuan Shi, Hong Qin, Nathaniel J. Fisch
Proposals to reach the next generation of laser intensities through Raman or Brillouin backscattering have centered on optical frequencies. Higher frequencies are beyond the range…
Effective action approach to wave propagation in scalar QED plasmas
Yuan Shi, Nathaniel J. Fisch, Hong Qin
A relativistic quantum field theory with nontrivial background fields is developed and applied to study waves in plasmas. The effective action of the electromagnetic 4-potential is…
