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…
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…
Ultrahigh mobility and giant magnetoresistance in the Dirac semimetal CdAs
Tian Liang, Quinn Gibson, Mazhar N. Ali +3
Dirac semimetals and Weyl semimetals are 3D analogs of graphene in which crystalline symmetry protects the nodes against gap formation [1-3]. NaBi and CdAs were predict…
Superconducting properties and electronic structure of NaBi
S K Kushwaha, J W Krizan, Jun Xiong +5
Resistivity, dc magnetization, and heat capacity measurements are reported for superconducting NaBi. Tc, the electronic contribution to the specific heat γ, the ΔCp/γTc ratio, and…
The magnetic phase diagram of underdoped YBa2Cu3Oy inferred from torque magnetization and thermal conductivity
Fan Yu, Max Hirschberger, Toshinao Loew +11
Strong evidence for charge-density correlation in the underdoped phase of the cuprate YBa2Cu3Oy was obtained by nuclear magnetic resonance (NMR) and resonant x-ray scatter- ing. Th…
