5 days agoAcademics : Nature

The Books & Arts article 'Final ascent of physics' (Nature549, 331–332; 2017) incorrectly stated that Special Relativity and Classical Field Theory is the last book in the Theoretical Minimum series, and described it as “historical” instead of

"What Sparked the Big Bang?" --The Black Hole at the Beginning of the Universe (WATCH Today's 'Galaxy' Classic)

The Big Bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three researchers at Canada's Perimeter Institute for Theoretical Physics propose that the Big Bang...        

Theoretical physics: When the doer met the dreamer

last weekAcademics : Nature

Graham Farmelo applauds a study on the productive friendship of two very different physicists.

Gravitational twists help theoretical physicists shed light on quantum complexity

(University of Oxford) Oxford University scientists address the problem of quantum complexity, identifying Monte-Carlo simulations as a particular physical phenomenon that cannot be captured by any local quantum. The work looks at the challenging 'sign problem.'

Special Relativity and Classical Field Theory

For quite a while Leonard Susskind has been giving some wonderful courses on physics under the name “The Theoretical Minimum”, pitched at a level in between typical popularizations and standard advanced undergraduate courses. This is a great idea, since there … Continue reading ?

On top of the top quark—new ATLAS experiment results

Physicists from the ATLAS Experiment at CERN have presented exciting new results at the 10th International Workshop on Top Quark Physics (TOP2017), held in Braga (Portugal). The conference brought together experimental and theoretical physicists specialising in the heaviest known elementary particle: the top quark.

Synopsis: Tackling Electronic Correlations

A new “first principles” simulation method could broaden the range of strongly correlated materials whose properties can be theoretically predicted. [Physics] Published Thu Sep 21, 2017

New Quantum Gravity Theory of the Big Bang --"We Need Another Picture of the Early Infant Universe"

The beginning of our universe – if there is one – is one of the big open questions in theoretical physics. The big bang is one of science’s great mysteries, and it seems the plot has thickened thanks to new...        

Physicists predict nonmetallic half-metallicity

A team of researchers from the Moscow Institute of Physics and Technology (MIPT) and the Institute for Theoretical and Applied Electrodynamics (ITAE) of the Russian Academy of Sciences (RAS), in collaboration with a colleague from RIKEN...Show More Summary

Physicists predict nonmetallic half-metallicity

(Moscow Institute of Physics and Technology) The team of researchers, which included physicists from Russia and Japan, has demonstrated a theoretical mechanism for achieving half-metallicity that requires no transition metal atoms. This possibility would have a number of useful applications, including in implantable devices.

Physicists predict nonmetallic half-metallicity

A team of researchers of the Russian Academy of Sciences (RAS), in collaboration with a colleague from RIKEN (Institute for Physical and Chemical Research in Japan), has provided theoretical proof of the existence of a new class of materials, spin-valley half-metals. Show More Summary

NSF CAREER award advances work in fundamental physics

(University of Houston) A theoretical physicist from the University of Houston seeking answers to fundamental questions about the nature of the universe has received a five-year, $475,000 Early CAREER award from the National Science Foundation to continue her work.

Dara Ó Briain: ‘Poo is a gateway drug, then I hit them with the cosmology’

The comedian and TV presenter on his new children’s book and standup show, being starstruck by Stephen Hawking, and David Beckham’s weird way with Lego Wicklow-born Dara Ó Briain, 45, studied maths and theoretical physics at University College Dublin. Show More Summary

Synopsis: Strong Force Model for Weak Force Reactions

A quark-based model called lattice QCD provides theoretical predictions for two weak-force-driven reactions—proton fusion and tritium decay. [Physics] Published Thu Aug 10, 2017

GR=QM?

In recent years a hot topic in some theoretical physics circles has been the 2013 “ER=EPR” conjecture first discussed by Maldacena and Susskind here. Every so often I try and read something explaining what this is about, but all such … Continue reading ?

Tiny Black Holes of the Big Bang --"Were the Furnace that Forged Heavy Elements of the Universe"

"Small black holes produced in the Big Bang can invade a neutron star and eat it from the inside," said George Fuller, a theoretical astrophysicist and professor of physics who directs UC San Diego's Center for Astrophysics and Space Sciences....        

Synopsis: Powering up Magnetization

New theoretical work identifies a dynamic form of multiferroic behavior, in which a time-varying electric polarization induces magnetization in a material. [Physics] Published Mon Jun 19, 2017

Physicists study magnetic impurities in topological insulators

A group of physicists from MIPT and the Landau Institute for Theoretical Physics of the Russian Academy of Sciences are now one step closer to finding applications for topological insulators—materials with remarkable electrical properties, which until recently, were regarded as merely hypothetical.

The brain may learn by building 11-dimensional "sandcastles"

4 months agoTechnology / Gadgets : Gizmag

We're all familiar with four dimensions – height, width, depth and time – but according to theoretical physics, the universe could be composed of as many as 11 dimensions. If you have a hard time wrapping your head around how those extra...Show More Summary
