Nonequilibrium Casimir pressures in liquids under shear
J. M. Ortiz de Zárate, T. R. Kirkpatrick, J. V. Sengers
In stationary nonequilibrium states coupling between hydrodynamic modes causes thermal fluctuations to become long ranged inducing nonequilibrium Casimir pressures. Here we conside…
Giant Casimir non-equilibrium forces drive coil to globule transition in polymers
Himadri S. Samanta, Mauro L. Mugnai, T. R. Kirkpatrick +1
We develop a theory to probe the effect of non-equilibrium fluctuation-induced forces on the size of a polymer confined between two horizontal thermally conductive plates subject t…
The quantum ferromagnetic transition in a clean Kondo lattice is discontinuous
T. R. Kirkpatrick, D. Belitz
The Kondo-lattice model, which couples a lattice of localized magnetic moments to conduction electrons, is often used to describe heavy-fermion systems. Because of the interplay be…
Why Non-equilibrium is Different
J. R. Dorfman, T. R. Kirkpatrick, J. V. Sengers
The 1970 paper, "Decay of the Velocity Correlation Function" [Phys. Rev. A1, 18 (1970), see also Phys. Rev. Lett. 18, 988 (1967)] by Berni Alder and Tom Wainwright, demonstrated, b…
Superconductivity and Quantum Phase Transitions in Weak Itinerant Ferromagnets
T. R. Kirkpatrick, Thomas Vojta, D. Belitz +1
It is argued that the phase transition in low-T_c clean itinerant ferromagnets is generically of first order, due to correlation effects that lead to a nonanalytic term in the free…
Annealed disorder, rare regions, and local moments: A novel mechanism for metal-insulator transitions
D. Belitz, T. R. Kirkpatrick, Thomas Vojta
Local magnetic moments in disordered sytems can be described in terms of annealed magnetic disorder, in addition to the underlying quenched disorder. It is shown that for nonintera…
Quantum critical behavior of itinerant ferromagnets
Thomas Vojta, D. Belitz, T. R. Kirkpatrick +1
We investigate the quantum phase transition of itinerant ferromagnets. It is shown that correlation effects in the underlying itinerant electron system lead to singularities in the…
The disordered Fermi-liquid fixed point and its instabilities
D. Belitz, T. R. Kirkpatrick
The concept of a disordered Fermi-liquid fixed point is introduced and used to understand various properties of disordered metals within a unifying framework. Corrections to scalin…

R. Narayanan, Thomas Vojta, D. Belitz +1
The effects of quenched disorder on the critical properties of itinerant quantum antiferromagnets and ferromagnets are considered. Particular attention is paid to locally ordered s…
Influence of rare regions on magnetic quantum phase transitions
R. Narayanan, Thomas Vojta, D. Belitz +1
The effects of quenched disorder on the critical properties of itinerant quantum magnets are considered. Particular attention is paid to locally ordered rare regions that are forme…
First order transitions and multicritical points in weak itinerant ferromagnets
D. Belitz, T. R. Kirkpatrick, Thomas Vojta
It is shown that the phase transition in low-T_c clean itinerant ferromagnets is generically of first order, due to correlation effects that lead to a nonanalytic term in the free…
Effective-field-theory approach to persistent currents
H. J. Bussemaker, T. R. Kirkpatrick
Using an effective-field-theory (nonlinear sigma model) description of interacting electrons in a disordered metal ring enclosing magnetic flux, we calculate the moments of the per…
Quantum critical behavior of clean itinerant ferromagnets
Thomas Vojta, D. Belitz, R. Narayanan +1
We consider the quantum ferromagnetic transition at zero temperature in clean itinerant electron systems. We find that the Landau-Ginzburg-Wilson order parameter field theory break…
A metal-insulator transition as a quantum glass problem

We discuss a recent mapping of the Anderson-Mott metal-insulator transition onto a random field magnet problem. The most important new idea introduced is to describe the metal-insu…
Quantum critical behavior of disordered itinerant ferromagnets
T. R. Kirkpatrick, D. Belitz

Breakdown of Landau-Ginzburg-Wilson theory for certain quantum phase transitions
T. Vojta, D. Belitz, R. Narayanan +1
The quantum ferromagnetic transition of itinerant electrons is considered. It is shown that the Landau-Ginzburg-Wilson theory described by Hertz and others breaks down due to a sin…
Anderson-Mott transition as a quantum glass problem
D. Belitz, T. R. Kirkpatrick
We combine a recent mapping of the Anderson-Mott metal-insulator transition on a random-field problem with scaling concepts for random-field magnets to argue that disordered electr…
Quantum ferromagnetic transition in disordered itinerant electron systems
D. Belitz, T. R. Kirkpatrick
An effective field theory is derived for the ferromagnetic transition of diffusive electrons at T=0. The static disorder which leads to diffusive electron dynamics induces an effec…

K. I. Wysokinski, W. Park, D. Belitz +1
We consider the mobility of electrons in an environment of static hard-sphere scatterers, which provides a realistic description of electrons in Helium gas. A systematic expansion…
