| Meeting on Quantum Gravity 9 Jan 2018, Jerusalem, Danciger B seminar room program News6/2017 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 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 Israel Science Foundation
(ISF) rejects
individual grant proposal in a rare and puzzling
procedure prior to external referee process. 2/2015 Accepted the position of Head
of physics studies at the department
starting October 2015. Research to continue at
full speed. |
