With a widely available magnetic field of 10 T, one can attain the quantum limit in bismuth and graphite. At zero magnetic field, these two elemental semi-metals host a dilute liquid of carriers of both signs. All quasi-particles are confined to a few Landau tubes, when the quantum limit is attained. Each time a Landau tube is squeezed before definitely leaving the Fermi surface, the Nernst response sharply peaks. For bismuth, additional Nernst peaks, unexpected in the non-interacting picture…

High-field peculiarities of galvanomagnetic quantum oscillations in Bi bicrystals with nano-width superconducting crystallite interfaces
Angle-resolved Landau spectrum of electrons and holes in bismuth
In elemental bismuth, emptying the low-index Landau levels is accompanied by giant Nernst quantum oscillations. The Nernst response sharply peaks each time a Landau level intersects the chemical…
Critical point for Bose–Einstein condensation of excitons in graphite
TLDR
By quantifying the mass and the density of the electron–hole pairs, this paper identifies a critical temperature of 9.2 K and a critical magnetic field of 47 T as the cradle of the Bose–Einstein condensation of excitons in graphite and radically revises the nature of the field-induced phase transition ingraphite and its boundaries.

Anomalous Nernst effect in strained graphene coupled to a substrate inducing a time-reversal symmetry breaking
A novel anomalous Nernst effect in graphene engineered by a strain and coupled to an environment with a broken time-reversal breaking is predicted. We consider the Haldane model (1988 Phys. Rev.…

Seit Ende der 1960er Jahre konzentrierte sich die Tieftemperaturforschung der Humboldt-Universitat auf das Verhalten der Ladungstrager von Metallen und Halbleitern in einem auseren Magnetfeld. Diese…
AC measurement of the Nernst effect of thin films at low temperatures.
TLDR
Using AC heating power and 2ω measurement, this work is able to achieve sub-nanovolt sensitivity in 20 nm-30 nm thin superconducting films on a glass substrate, compared to a sensitivity of ∼10 nV using DC techniques on the same setup.

Phase diagram of bismuth in the extreme quantum limit.
TLDR
A study of the angular-dependent Nernst effect in bismuth, which establishes the existence of ultraquantum field scales on top of its complex single-particle spectrum.

We present a transport study of semi-metallic bismuth in the presence of a magnetic field applied along the trigonal axis extended to 55 T for electric conductivity and to 45 T for thermoelectric…
Oscillating Nernst-Ettingshausen effect in bismuth across the quantum limit.
TLDR
This work reports on the first study of metallic thermoelectricity in this regime, and notes a qualitative agreement with a theory invoking current-carrying edge excitations.
Transport properties of bismuth in quantising magnetic fields
The amplitude of the magnetotransport components for Bi (magnetoresistance, Hall, magneto-Seebeck and Nernst) in the phonon-drag region have been studied. Measurements were extended to the quantum…
Signatures of Electron Fractionalization in Ultraquantum Bismuth
TLDR
The results suggest that this bulk element may host an exotic quantum fluid reminiscent of the one associated with the fractional quantum Hall effect and raise the issue of electron fractionalization in a three-dimensional metal.

TLDR
According to the data, this amplitude of the Nernst response measured in various metals in the low-temperature limit is roughly set by the ratio of electron mobility to Fermi energy, in agreement with the implications of semi-classical transport theory.
Thermoelectric response near a quantum critical point: the case of CeCoIn5.
TLDR
The dimensionless ratio of the Seebeck coefficient to the electronic specific heat shows a minimum at a temperature close to threshold of the quasiparticle formation and the Nernst coefficient behaves anomalies in puzzling contrast with other superconductors and standard vortex dynamics.
Phase Transitions of Dirac Electrons in Bismuth
TLDR
By using torque magnetometry, the observation of sharp field-induced phase transitions into a state with striking magnetic anisotropy is reported, consistent with the breaking of the threefold valley degeneracy.
