Laser Acceleration and High Field Science
Toshiki Tajima (LMU München and École Normale Supérieure)
Seminar Room 3, 15:00h
The emergence of intense lasers enables us to take a fresh
outlook on accelerator physics and consequently opportunities
for high energy and related physics. Laser acceleration not only
provides one of the future options of HEP colliders, but also
paves ways for broader scientific and societal applications,
including a possibly more compact FEL. Moreover, intense
lasers open an avenue of high field science not just in high
momentum approaches, but also in high amplitude physics.
The vacuum physics exploration is one such example. The
permeability of vacuum changes in the presence of high fields
and nonlinear optics of vacuum can reveal nonlinear QED, the
Schwinger process, and perhaps even the QCQ physics.
The approach by high fields may reveal previously invisible
fields such as dark matter and dark energy. I will discuss the
current status and possible future developments.
