Competition between orbital effects, Pauli limiting, and Fulde-Ferrell-Larkin-Ovchinnikov states in 2D transition metal dichalcogenide superconductors
Chang-woo Cho, Cheuk Yin Ng, Mahmoud Abdel-Hafiez +4
We compare the upper critical field of bulk single-crystalline samples of the two intrinsic transition metal dichalcogenide (TMD) superconductors, 2H-NbSe2 and 2H-NbS2, in high mag…
Superconductivity beyond Pauli's limit in bulk NbS2: Evidence for the Fulde-Ferrell-Larkin-Ovchinnikov state
Chang-woo Cho, Jian Lyu, Cheuk Yin Ng +4
We present magnetic torque, specific heat and thermal expansion measurements combined with a piezo rotary positioner of the bulk transition metal dichalcogenide (TMD) superconducto…
Nodal and nematic superconducting phases in NbSe2 monolayers from competing superconducting channels
Chang-woo Cho, Jian Lyu, Liheng An +10
Transition metal dichalcogenides like 2H-NbSe2 in their two-dimensional (2D) form exhibit Ising superconductivity with the quasiparticle spins are firmly pinned in the direction pe…
-vestigial nematic order due to superconducting fluctuations in the doped topological insulator NbBiSe and CuBiSe
Chang-woo Cho, Junying Shen, Jian Lyu +10
A state of matter with a multi-component order parameter can give rise to vestigial order. In the vestigial phase, the primary order is only partially melted, leaving a remaining s…
Spectroscopic Fingerprint of Chiral Majorana Modes at the Edge of a Quantum Anomalous Hall Insulator / Superconductor Heterostructure
J. Shen, J. Lyu, J. Z. Gao +14
With the recent discovery of the quantum anomalous Hall insulator (QAHI), which exhibits the conductive quantum Hall edge states without external magnetic field, it becomes possibl…
High-pressure effects on isotropic superconductivity in the iron-free layered pnictide superconductor BaPd2As2
M. Abdel-Hafiez, Y. Zhao, Z. Huang +14
While the layered 122 iron arsenide superconductors are highly anisotropic, unconventional, and exhibit several forms of electronic orders that coexist or compete with superconduct…
