Fermi-to-Bose crossover in a trapped quasi-2D gas of fermionic atoms
AV Turlapov, MY Kagan - Journal of Physics: Condensed Matter, 2017 - iopscience.iop.org
The physics of many-body systems where particles are restricted to move in two spatial
dimensions is challenging and even controversial: on one hand, neither long-range order …

Substrate mediated nitridation of niobium into superconducting Nb2N thin films for phase slip study
Here we report a novel nitridation technique for transforming niobium into hexagonal Nb2N
which appears to be superconducting below 1K. The nitridation is achieved by high …

Dimensional crossover in ultracold Fermi gases from functional renormalization
BM Faigle-Cedzich, JM Pawlowski, C Wetterich - Physical Review A, 2021 - APS
We investigate the dimensional crossover from three to two dimensions in an ultracold Fermi
gas across the whole BCS-BEC crossover. Of particular interest is the strongly interacting …

Towards understanding the dimensional BCS-BEC crossover and its spectral properties
BM Faigle-Cedzich - 2022 - archiv.ub.uni-heidelberg.de
In this thesis we investigate several aspects of ultracold Fermi gases within the framework of
the functional renormalisation group (fRG). The first part concerns the determination of the …

Pseudogap regime of a two-dimensional uniform Fermi gas
M Matsumoto, R Hanai, D Inotani… - Journal of the Physical …, 2018 - journals.jps.jp
We investigate pseudogap phenomena in a two-dimensional Fermi gas. Including pairing
fluctuations within a self-consistent T-matrix approximation, we determine the pseudogap …
