When matter is cooled from high temperatures, collective instabilities develop amongst its constituent particles that lead to new kinds of order. 1 An anomaly in the specific heat is a classic signature of this phenomenon. Usually the associated order is easily identified, but sometimes its nature remains elusive. The heavy fermion metal URu 2 Si 2 is one such example, where the order responsible for the sharp specific heat anomaly at T 0 = 17K has remained unidentified despite more than…

Proximity to a critical point driven by electronic entropy in URu2Si2
The strongly correlated actinide metal URu 2 Si 2 exhibits a mean field-like second order phase transition at T o  ≈ 17 K, yet lacks definitive signatures of a broken symmetry. Meanwhile, various
Isoelectronic perturbations to f-d-electron hybridization and the enhancement of hidden order in URu2Si2
TLDR
This work tracks the temperature increase of the resistive signature of the hidden-order (HO) phase transition in URu2Si2, a mysterious phase with unknown order parameter and presents a scenario in which the application of pressure or the isoelectronic substitution of Fe and Os ions for Ru results in an increase in the hybridization of the U-5f-electron and transition metal d-Electron states which leads to electronic instability in the paramagnetic phase.
Gaussian fluctuation corrections to a mean-field theory of complex hidden order in URu2Si2
Hidden-order phase transition in the heavy-fermion superconductor URu$_2$Si$_2$ exhibits the mean-field-like anomaly in temperature dependence of heat capacity. Motivated by this observation, here we
Pressure Effects on the 4f Electronic Structure of Light Lanthanides.
TLDR
It is shown that in the case of Ce, mixing of a higher atomic angular momentum state, driven by the increased hybridization, acts to obscure the expected satellite reduction, which is more consistently associated with evolution of the satellite than the reduction of the 4f moment.
Critical Theory of Non-Fermi Liquid Fixed Point in Multipolar Kondo Problem
When the ground state of a localized ion is a non-Kramers doublet, such localized ions may carry multipolar moments. For example, Pr$^{3+}$ ions in a cubic environment would possess quadrupolar and
Landau theory of multipolar orders in Pr(Y)2X20 Kondo materials ( Y=Ti , V, Rh, Ir; X=Al , Zn)
A series of Pr(TM)$_2$X$_{20}$ (with TM=Ti,V,Rh,Ir and X=Al,Zn) Kondo materials, containing non-Kramers Pr$^{3+}$ $4f^2$ moments on a diamond lattice, have been shown to exhibit intertwined orders

The manganese tellurate Li2MnTeO6 consists of trigonal spin lattices made up of Mn4+ (d3, S = 3/2) ions. The magnetic properties of this compound were characterized by several experimental
Quadrupolar ordering and exotic magnetocaloric effect in RB4 (R = Dy, Ho)
TLDR
Based on Landau theory, a new mechanism for a large entropy change with low magnetic fields in rare-earth tetraborides, especially for Ho1-xDyxB4 (x = 0.0, 0.5, and 1.0), is proposed.

TLDR
P peaks have not been identified in the magnetic excitation spectra, but instead a continuous spectrum of scattering peaked around the ordering wave vector indicates the presence of overdamped antiferromagnetically correlated spin fluctuations.

TLDR
Electrical-resistivity measurements rho(T,H) on single-crystal URu/sub 2/Si/ sub 2/ have been performed between 0.3 and 300 K in fields up to 7 T and an upper antiferromagnetic transition is clearly discerned by a ''Cr-like'' anomaly at roughly-equal17 K which also marks the onset of a strong, positive rho (H).
