Metallic quantum ferromagnets

M Brando, D Belitz, FM Grosche, TR Kirkpatrick - Reviews of modern Physics, 2016 - APS
An overview of quantum phase transitions (QPTs) in metallic ferromagnets, discussing both
experimental and theoretical aspects, is given. These QPTs can be classified with respect to …

Quantum order-by-disorder in strongly correlated metals

AG Green, G Conduit, F Krüger - Annual Review of Condensed …, 2018 - annualreviews.org
Entropic forces in classical many-body systems, eg, colloidal suspensions, can lead to the
formation of new phases. Quantum fluctuations can have similar effects: spin fluctuations …

Inhomogeneous phase formation on the border of itinerant ferromagnetism

GJ Conduit, AG Green, BD Simons - Physical review letters, 2009 - APS
A variety of analytical techniques suggest that quantum fluctuations lead to a fundamental
instability of the Fermi liquid that drives ferromagnetic transitions first order at low …

Quantum tricritical points in NbFe2

S Friedemann, WJ Duncan, M Hirschberger, TW Bauer… - Nature Physics, 2018 - nature.com
Quantum critical points (QCPs) emerge when a second-order phase transition is suppressed
to zero temperature. In metals the quantum fluctuations at such a QCP can give rise to new …
