6/2017 Chaos,
Quantum Mechanics and Black Holes - a special public
lecture from the frontier of theoretical physics delivered at
the Hebrew University by Prof. Stephen Shenker on 25
June 2017, see also
5/2017 A TV appearance on time
travel (Hebrew, channel KAN).
5/2017 A hypothesis regarding a relation
between bat evolution and a period of darkness following an
asteroid impact appears in "The K-Pg event as a key to bat
evolution", see here.
4/2017 The SFI method is used to achieve a novel
evaluation of a Feynman diagram in "The Vacuum Seagull:
evaluating a 3-loop Feynman diagram with 3
mass scales, see here.
1/2017 Recognized as Excellent teacher
of the Hebrew University for previous school year.
8/2016 Michael (Misha) Smolkin joins
the faculty of the theoretical High Energy group.
8/2016 Presented "Effective
black hole degrees of freedom at low frequencies" at
the Inward Bound conference on Black Holes and Emergent Spacetime,
17-20 August 2016, NORDITA.
6/2016 "Bubble diagram through the
Symmetries of Feynman Integrals method" appears. The
Symmetries of Feynman Integrals (SFI) method is generalized to
include diagrams with external legs, and the 1-loop propagator
diagram ("the bubble") is analyzed and its value is reproduced
through solving the SFI equations.
4/2016 The Racah Institute hires Yonit
Hochberg and Eric Kuflik thereby establishing a
long-awaited for group in High Energy Phenomenology. They defer
their arrival to the following year.
4/2016 "The algebraic locus of Feynman
integrals" appears.
It defines a certain locus in the parameter space where a Feynman
integral can be reduced to a linear combination of contracted
diagrams.
11/2015 Joined the iCore grant and Center
of Research Excellence in The Quantum Universe.
8/2015 The group mourns the passing of Prof. Jacob
Bekenstein, a black hole pioneer and a model
physicist.
7/2015 "Symmetries of Feynman integrals and the Integration By Parts Method" appears. This work associates with Integration By Parts, a method to compute Feynman integrals having some 1000 citations, a group action on parameter space and studies its consequences.
3/2015 The course "Analytical mechanics"
77303 is rated as the 3rd best among the 65 physics courses
in the teaching evaluation questionnaire.
3/2015 Organized Hebrew
Un. - Humboldt Un. meeting - hosting the group of
Matthias Staudacher, 22-29 March, Jerusalem.
3/2015 Israel Science Foundation (ISF) rejects
individual grant proposal in a rare and puzzling procedure prior
to external referee process.
2/2015 Michael (Misha) Smolkin accepted our
offer for a faculty position, joining the high energy group
in summer 2016. Best wishes for success to Misha and the whole
group!
8/2014 "Leading anomalies, the drift
Hamiltonian, and the relativistic two body problem"
by Barak Kol and Bernard Nabet appears. This work
proposes to solve the equations of motion by concentrating on
relativistic anomalies and utilizing the Hamiltonian averaging
method for a rather elegant and intuitive formulation.
Presented "The effective field theory approach
to the two body problem in Einstein's gravity" at the Vienna
university of technology and at the Wigner research
center (Budapest).
6/2014 "1-loop color structures and sunny
diagrams" by Barak Kol and Ruth Shir appears
4/2014 "Color
structures and permutations" and "Perturbative gauge
theory and 2+2=4" by Ruth Shir and Barak Kol appear.
These are our first papers on scattering amplitudes. They were
presented at the Oxford Mathematical Physics group.
1/2014 Congratulations to Ruth for winning the
Meidan fellowship (20k$/year for 3 years)
Presented "Self
force and equivalent periodic sources" (see 7/2013 below)
