Upper critical magnetic field of superconducting films with magnetic impurities
… The results were compared with the theory of Fulde and MakL This theory assumes that the electron-phonon coupling is weak, and that the interaction between the impurity spins and the conduction electron spins is weak. The theory predicts that the pair-breaking effect of the magnetic impurities …

Communal pairing in Fermi gases with attractive interactions
… systems include breached superfluids, Fulde–Ferrell–Larkin–Ovchinnikov theory, and pair density wave theory. We propose a further extension of a superconducting state, dubbed a communal pairing state, whose underlying components are superpositions of Cooper pairs that share …

Exploring strongly interacting gapless states : cuprates, pair density waves, and fluctuating superconductivity
… superconductors. In Chapter 2, we study how Fulde-Ferrell state, the simplest form of PDW, responds to incident light. The collective motion of the condensate plays a key role; gauge invariance guides us to the correct result. From Chapter 3 to Chapter 7, we construct a pseudogap metallic …

Searching For FFLO States in Ultracold Polarized Fermi Gases: A Numerical Approach
… both 3D and 1D especially focusing on the exotic Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phase, which is characterized by a spatially oscillating order parameter. In 3D, we solve for the stationary states of trapped imbalanced Fermi gases in a wide range of parameter space with a home-made …

Growth and characterisation of Niobium/Gadolinium superconductor-ferromagnet nanocomposites
… field as surprisingly! predicted first by Fulde and Ferrel [1] and independently by Larkin and Ovchinikov [2] nearly 50 years ago. This coexistence has already been observed experimentally in both bulk samples [3, 4] and in thin films [5-7] which result from a different type of …

Condensation and pairing in inhomogeneous cold atomic and electronic systems
… phase with oscillatory pairing, the so-called Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, and an unpaired completely spin-polarized phase. We present numerical profiles of key parameters of the phase diagram as well as observable signatures of the oscillatory pairing phase. The third topic …

Periodically Modulated Electronic States in Natural Superlattices
… we observe long-anticipated signatures of 2D Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconductivity for M = Nb and preliminary evidence for a correlated insulator ground state when M = V. We conclude by discussing prospects of identifying new members of this family and, more broadly, new …

Spin-Mediated Transport in Superconducting and Spin-Polarized Systems

Quasi-One-Dimensional Ultracold Fermi Gases
… paves the way to search for the exotic FFLO (Fulde-Ferrell-Larkin-Ovchinnikov) superconductor. While most superconductors do not coexist with magnetism, the FFLO phase requires large magnetic fields to support its pairing mechanism. Additionally, this phase is more likely to be found in lower …

Topics in the Theory of Quantum Degenerate Gases

Topological insulators and semimetals in the presence of interactions
… Zeeman effect to the TI surface, we find that Fulde-Ferrell(FF) state can be induced in the conventional superconductor. This occurs when the inverse proximity effect(IPE) of the TI to the superconductor is large enough that the normal band of the superconductor possesses a proximity induced …

Pair density wave superconducting states and statistical mechanics of dimers
… weak-coupling limit, in contrast to the usual Fulde-Ferrell-Larkin-Ovchinnikov phases, which require strong coupling physics in addition to a large magnetic field (and often both). In chapter 3 we show that the pair-density-wave (PDW) superconducting state emergent in extended …
