The Planckian metal is a special case of a strange metal, in which the linear-in-temperature scattering rate reaches a universal limit. Here the authors study this state in a heavy-fermion superconductor in magnetic field and propose a microscopic me

Abstract The interplay of topology with magnetism in Weyl semimetals recently arose to a vanguard topic, because of novel physical scenarios with anomalous transport properties. Here, we address the charge dynamics of the noncentrosymmetric and ferro

Dirac semimetals feature Dirac cones with topologically nontrivial states in the bulk that are protected by crystalline symmetries. They attract considerable attention due to rich quantum states and properties of interest, such as high Fermi velociti

A common feature of many transition metal materials is global symmetry breaking at low temperatures. Here the authors show that such materials are characterized by fluctuating symmetry-lowering distortions that exist pre-formed in higher temperature

Low-temperature (down to ∼50 mK) thermal conductivity measurements with the heat flow direction along the interplane tetragonal c axis, κ_{c}, were used to study the superconducting state of heavy fermion CeIrIn_{5}. Measurements were performed in

We report a detailed study of electrical and thermal transport properties in 2H-M_{x}TaS_{2} (M=Mn, Co) magnets where M atoms are intercalated in the van der Waals gap. The intercalation induces ferromagnetism (FM) with an easy-plane anisotropy in 2H

We report ferromagnetism in 2H-Co_{0.22}TaS_{2} single crystals where Co atoms are intercalated in the van der Waals gap, and a systematic study of its magnetic critical behavior in the vicinity of T_{c}∼28 K. The obtained critical exponents β=0.4

The contribution of bulk and surface to the electrical resistance along crystallographic b and c axes as a function of crystal thickness gives evidence for temperature-independent surface states in an antiferromagnetic narrow-gap semiconductor CrSb_{

We report discovery of antiferromagnetic semimetal EuZnSb_{2}, obtained and studied in the form of single crystals. Electric resistivity, magnetic susceptibility, and heat capacity indicate antiferromagnetic order of Eu with T_{N} = 20 K. The effecti
