Extremal Quantum States - A mathematical project “of immense beauty”
U of T Physics Graduate student Aaron Goldberg (supervised by Professor Daniel James) and colleagues have found a way to characterize “quantumness” or the chasm between the classical and quantum realms.

Aephraim Steinberg, co-director of CIFAR’s Quantum Information Science Program, led a team that timed atoms’ mysterious quantum behaviour.
How long does it take to do the apparently impossible? Knowing might unlock better quantum computers and a deeper understanding of physics.

Why isn’t there nothing in the universe? Physicists are one step closer to an answer
In a paper published in the journal Nature earlier this year, a team of physicists reported the best evidence yet for an asymmetry between neutrinos and anti-neutrinos that could explain our matter-dominated universe.

Do Neutrinos Crack Nature’s Mirror?
Emeritus Professor John Martin, former professor Hiro Tanaka (now at Stanford) and his senior UofT PhD student Trevor Towstego are among the nearly 500 authors of a Nature paper from the T2K experiment published today, which presents results giving the strongest constraint yet on the so-called CP phase governing the breaking of symmetry between matter and antimatter in neutrino oscillations

Magnetic Field Induced Quantum Phases in a Tensor Network Study of Kitaev Magnets
In a recent published article in Nature Communication, a team of researchers from University of Tokyo and University of Toronto led by Prof Yong Baek Kim reported the discovery of a novel quantum ground state in theoretical models designed for the so-called Kitaev magnets in external magnetic field.

Theory of Two-Dimensional Nonlinear Spectroscopy for the Kitaev Spin Liquid
Mr Wonjune Choi and his Ph.D. supervisor Prof Yong Baek Kim proposed a new two-dimensional non-linear spectroscopy method for unambiguous detection of fractionalized particles in quantum spin liquids.

Professor Paramekanti and collaborators discover new octupolar magnets
Magnetic solids derive their properties from the magnetic dipole moment of the electrons in the crystal. However, when many electrons interact, they can lead to new types of ordering arising from higher-rank multipole moments.
