Quasi-2D Fermi surface in the anomalous superconductor UTe2 [PDF]
Nature Communications, 2023 The heavy fermion paramagnet UTe2 exhibits numerous characteristics of spin-triplet superconductivity. Efforts to understand the microscopic details of this exotic superconductivity have been impeded by uncertainty regarding the underlying electronic ...

Super-geometric electron focusing on the hexagonal Fermi surface of PdCoO2 [PDF]
Nature Communications, 2019 Ballistic electron beams in clean metals can be focused by passing currents through well designed contraptions, which is mostly done in isotropic materials described by a circular Fermi surface.

Nonlinear magnetotransport shaped by Fermi surface topology and convexity. [PDF]
Nat Commun, 2019 The nature of Fermi surface defines the physical properties of conductors and many physical phenomena can be traced to its shape. Although the recent discovery of a current-dependent nonlinear magnetoresistance in spin-polarized non-magnetic materials ...

Creating Majorana modes from segmented Fermi surface [PDF]
Nature Communications, 2021 Despite striking progress in promoting Majorana physics to topological quantum computation, there are many disadvantages in existing material platforms. Here, Papaj and Fu propose a new two-dimensional system for realization of Majorana physics based on ...

Quantum chaos on a critical Fermi surface. [PDF]
Proc Natl Acad Sci U S A, 2017 Significance All high-temperature superconductors exhibit a remarkable “strange metal” state above their critical temperatures. A theory of the strange metal is a prerequisite for a deeper understanding of high-temperature superconductivity, but the ...

Pseudogap phase of cuprate superconductors confined by Fermi surface topology. [PDF]
Nat Commun, 2017 The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which sets in at a doping p* that is material-dependent.

Fermi surface topology and magnetotransport in semimetallic LuSb. [PDF]
Sci Rep, 2017 Several rare-earth monopnictides were shown to exhibit extreme magnetoresistance and field-induced low-temperature plateau of electrical resistivity. These features are also hallmarks of topological semimetals, thus the family is intensively explored ...

Deformation of the Fermi surface of a spinless two-dimensional electron gas in presence of an anisotropic Coulomb interaction potential [PDF]
Scientific Reports, 2021 We consider the stability of the circular Fermi surface of a two-dimensional electron gas system against an elliptical deformation induced by an anisotropic Coulomb interaction potential.

Butterfly magnetoresistance, quasi-2D Dirac Fermi surface and topological phase transition in ZrSiS. [PDF]
Sci Adv, 2016 An unusual angle-dependent topological phase transition and butterfly magnetoresistance were found in the Dirac semimetal ZrSiS. Magnetoresistance (MR), the change of a material’s electrical resistance in response to an applied magnetic field, is a ...
