Unconventional Superconductivity in Heavy Fermion UTe2 [PDF]

Journal of the Physical Society of Japan, 2019
We grew single crystals of the recently discovered heavy fermion superconductor UTe2, and measured the resistivity, specific heat and magnetoresistance.

Chiral Majorana fermion modes in a quantum anomalous Hall insulator–superconductor structure [PDF]

Science, 2016
A propagating Majorana mode Although Majorana fermions remain elusive as elementary particles, their solid-state analogs have been observed in hybrid semiconductor-superconductor nanowires.

Entanglement in a fermion chain under continuous monitoring [PDF]

SciPost Physics, 2018
We study the entanglement entropy of the quantum trajectories of a free fermion chain under continuous monitoring of local occupation numbers. We propose a simple theory for entanglement entropy evolution from disentangled and highly excited initial ...

Massless Dirac Fermions on a Space‐Time Lattice with a Topologically Protected Dirac Cone

Annalen der Physik, Volume 534, Issue 12, December 2022., 2022
Fermion doubling is a lattice artefact that appears if one discretizes the Dirac equation of massless electrons. One can work around this obstacle by replacing the linear dispersion by a sawtooth. Here it is shown that this method opens a gap at the Dirac point of the band structure.

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

Advanced Physics Research, EarlyView., 2023
The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Field-Reentrant Superconductivity Close to a Metamagnetic Transition in the Heavy-Fermion Superconductor UTe2 [PDF]

Journal of the Physical Society of Japan, 2019
We present a study of the upper critical field of the newly discovered heavy fermion superconductor UTe2 by magnetoresistivity measurements in pulsed magnetic fields up to 60 T and static magnetic ...

Direct optical detection of Weyl fermion chirality in a topological semimetal [PDF]

Nature Physics, 2017
Measuring the photocurrent response to circularly polarized mid-infrared light provides direct access to the chirality of Weyl fermions in Weyl semimetals — the property responsible for a range of exotic phenomena. A Weyl semimetal is a novel topological

Phenomenological profile of scotogenic fermionic dark matter

Journal of High Energy Physics, 2023
We consider the possibility that neutrino masses arise from the exchange of dark matter states. We examine in detail the phenomenology of fermionic dark matter in the singlet-triplet scotogenic model.

Discovery of topological Weyl fermion lines and drumhead surface states in a room temperature magnet [PDF]

Science, 2017
Magnetic Weyl semimetals Weyl semimetals (WSMs)—materials that host exotic quasiparticles called Weyl fermions—must break either spatial inversion or time-reversal symmetry. A number of WSMs that break inversion symmetry have been identified, but showing
