New Hsieh review “Towards properties on demand in quantum materials”

Quantum materials are on the ascent. This term embodies a vast portfolio of compounds and phenomena where ramifications of quantum mechanics are demonstrably real. Quantum materials are in the vanguard of contemporary physics in part because these systems afford an exceptional venue to uncover the many roles of symmetry, topology, dimensionality and strong correlations in [...]

Brandão study presents a new quantum algorithm related to semidefinite problems

A new Caltech study, by Fernando Brandão and collaborators, demonstates that quantum computing could be applied to speed up solutions to "semidefinite programs" a class of optimization problems."One of the goals of quantum computing is to speed up computations to levels that far exceed what classical computers can do," says Fernando Brandão, the Bren Professor [...]

New Paper MBL-mobile: Many-body-localized engine

Schematic of many-body-localized (MBL) engine. Figure 1 from the paper. Authors Nicole Yunger Halpern, Christopher White, IQIM/Burke Institute alum Sarang Gopalakrishnan and Gil Refael released a new paper in which they designed an engine formed from a many-body localized system. The project combines quantum many-body physics with quantum thermodynamic, and features two branches [...]
