Complexity, Phase Transitions, and Inference by Cristopher Moore (part 2)

                          



Complexity, Phase Transitions, and Inference by Cristopher Moore (part 2)

Δημοσιεύτηκε στις 3 Ιουλ 2016

There
is a deep analogy between statistical inference and statistical
physics. I will give a friendly introduction to both of these fields. I
will then discuss phase transitions in problems like community
detection in networks, and clustering of sparse high-dimensional data,
where if our data becomes too sparse or too noisy it becomes impossible
to find the underlying pattern; moreover, I will discuss optimal
algorithms that succeed as well as possible up to this point. Along the
way, I will visit ideas from computational complexity, random graphs,
random matrices, and spin glass theory.

School on Current Frontiers in Condensed Matter Research

URL: http://www.icts.res.in/program/cficmr16

DATES: Monday 20 Jun, 2016 - Wednesday 29 Jun, 2016

VENUE : Ramanujan Lecture Hall, ICTS Bangalore

DESCRIPTION:
Understanding
strongly interacting quantum many body systems is one of the major
frontiers in present day physics. Condensed matter physics provides a
wide panoply of systems where strong interaction between constituent
particles play a dominant role; some examples of such systems are high
temperature superconductors, spin-liquids, fractional quantum Hall
systems, and ultracold atoms in the strong-coupling regime. Recent
additions to this list include topological insulators/superconductors,
transition metal oxides and their heterostructures. These materials have
the added feature that they have strong spin-orbit coupling. The
interplay of strong interactions and strong spin-orbit coupling is
presently a frontier area of research in condensed matter physics.

This
program aims to introduce graduate students and post-docs to different
aspects of strongly interacting systems focusing on ideas which are
recently animating the condensed matter community world-wide. The
program will consist of a week-long pedagogical lectures from 20.06.2016
to 26.06.2016 on frontier areas, followed by three days of a discussion
meeting from 27.06.2016 to 29.06.2016 on related topics, presenting and
discussing the latest situation in these areas.

The school lecturers are :

Subir Sachdev (Harvard University)
Mohit Randeria ( The Ohio State University)
Jainendra Jain ( Penn State University)
Jay D. Sau ( University of Maryland, College Park )
Kedar Damle (Tata Institute of Fundamental Research, Mumbai)
Vijay Shenoy (Indian Institute of Science, Bangalore)
Diptiman Sen (Indian Institute of Science, Bangalore)

Juno Captures the 'Roar' of Jupiter

               



Juno Captures the 'Roar' of Jupiter

Δημοσιεύτηκε στις 30 Ιουν 2016

NASA's
Juno spacecraft has crossed the boundary of Jupiter's immense magnetic
field. Juno's Waves instrument recorded the encounter with the bow shock
over the course of about two hours on June 24, 2016. "Bow shock" is
where the supersonic solar wind is heated and slowed by Jupiter's
magnetosphere. It is analogous to a sonic boom on Earth. The next day,
June 25, 2016, the Waves instrument witnessed the crossing of the
magnetopause. "Trapped continuum radiation" refers to waves trapped in a
low-density cavity in Jupiter's magnetosphere.
