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 …

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 …

We consider the problem of fermions interacting with gapless long-wavelength collective
bosonic modes. The theory describes, among other cases, a ferromagnetic quantum-critical …

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 …

Ferromagnetic quantum criticality in clean metals has proven elusive due to fermionic soft
modes that drive the transition first order. We show that noncentrosymmetric metals with a …

The formation of new phases close to itinerant electron quantum critical points has been
observed experimentally in many compounds. We present a unified analytical framework to …

The behavior of matter near zero temperature continuous phase transitions, or “quantum
critical points” is a central topic of study in condensed matter physics. In fermionic systems …

Quantum critical points (QCPs), zero-temperature phase transitions, are windows to
fundamental quantum-mechanical phenomena associated with universal behaviour …

We study nonanalytic paramagnetic response of an interacting Fermi system both away and
in the vicinity of a ferromagnetic quantum phase transition (QCP). Previous studies found …

In low-temperature metallic magnets, ferromagnetic (FM) and antiferromagnetic (AFM)
orders can exist, adjacent to one another or concurrently, in the phase diagram of a single …
