Z topology and superconductivity from symmetry lowering of a 3D Dirac Metal AuPb
Leslie M. Schoop, Lilia S. Xie, Ru Chen +12
3D Dirac semi-metals (DSMs) are materials that have massless Dirac electrons and exhibit exotic physical properties It has been suggested that structurally distorting a DSM can cre…
3D Dirac semimetals: current materials, design principles and predictions of new materials
Quinn D. Gibson, Leslie M. Schoop, Lukas Muechler +5
Design principles and novel predictions of new 3D Dirac semimetals are presented, along with the context of currently known materials. Current materials include those based on a to…
Heavy Fermion Quantum Criticality and Destruction of the Kondo Effect in a Nickel Oxypnictide
Yongkang Luo, Leonid Pourovskii, S. E. Rowley +8
A quantum critical point arises at a continuous transformation between distinct phases of matter at zero temperature. Studies in antiferromagnetic heavy fermion materials have reve…
Paramagnetic to ferromagnetic phase transition in lightly Fe-doped CrB
Leslie M. Schoop, Max Hirschberger, Jing Tao +3
CrB displays temperature independent paramagnetism. We induce ferromagnetism by replacing less than of the Cr atoms by Fe. By the lowest Fe doping level made, Curie-Wei…
Heat capacity anomaly at the quantum critical point of the Transverse Ising Magnet CoNb_2O_6
Tian Liang, S. M. Koohpayeh, J. W. Krizan +3
The transverse Ising magnet Hamiltonian describing the Ising chain in a transverse magnetic field is the archetypal example of a system that undergoes a transition at a quantum cri…
Titanic Magnetoresistance in WTe2
Mazhar N. Ali, Jun Xiong, Steven Flynn +6
Magnetoresistance is the change of a material's electrical resistance in response to an applied magnetic field. In addition to its intrinsic scientific interest, it is a technologi…
