• Abstract: The current study is motivated by a difficulty to reconcile between particle number conservation and superconductivity. An alternative modeling, which is based on the hypothesis that disentanglement spontaneously ocuurs in quantum systems, is explored. The Fermi-Hubbard mode is employed to demonstrate a disentanglement-induced quantum phase transition into a state having a finite superconducting order parameter. Moreover, the effect of disentanglement on Josephson junction's current phase relation is explored.

  Local control and optical bilayer capabilities combined with spatially resolved measurements create a versatile toolbox. We show how coherent pairing correlations can be accessed in a partially particle-hole transformed and rotated basis. Finally, we introduce a scheme to measure momentum-resolved dopant densities, providing access to observables complementary to solid-state experiments.

• Fragmented superconductivity in the Hubbard model as solitons in Ginzburg-Landau theory [39.58317527488534]
  Superconductivity and charge density waves are observed in close vicinity in strongly correlated materials. We investigate the nature of such an intertwined state of matter stabilized in the phase diagram of the elementary $t$-$tprime$-$U$ Hubbard model. We provide conclusive evidence that the macroscopic wave functions of the superconducting fragments are well-described by soliton solutions of a Ginzburg-Landau equation.

  We investigate the onset of superconductivity in the Yukawa-Sachdev-Ye-Kitaev model. We find that the dynamical relaxation of undercooled states universally leads to superconductivity. Despite the strong correlations, the emerging order parameter dynamics are well captured by a coarse grained Ginzburg-Landau theory.

  We investigate transport through a proximitized integer quantum Hall edge. By examining the downstream conductance, we identify regimes in which sub-gap vortex levels mediate Andreev processes. We show that at finite temperature, and in the limit of a large number of vortices, the downstream conductance can average to zero, indicating that the superconductor effectively behaves like a normal contact.

We furthermore study the stability of the phases with respect to temperature within the mean-field approximation.

• Absence versus Presence of Dissipative Quantum Phase Transition in Josephson Junctions [0.0]
  Dissipative quantum phase transition has been widely believed to occur in a Josephson junction coupled to a resistor despite a lack of concrete experimental evidence. We reveal breakdown of previous perturbative arguments and defy the common wisdom that the transition always occurs at the quantum resistance. Our predictions can be tested in recent experiments realizing high-impedance long superconducting waveguides.

  We propose a mechanism for light-induced unconventional superconductivity in a two-valley semiconductor with a massive Dirac type band structure. We consider a circularly-polarized light pump and show that by controlling the detuning of the pump frequency relative to the band gap, different types of chiral superconductivity would be induced.

• Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations [77.34726150561087]
  The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. Here, we propose a theory-independent route to probe the full ETH in quantum simulators by observing the emergence of fluctuation-dissipation relations. Our work presents a theory-independent way to characterize thermalization in quantum simulators and paves the way to quantum simulate condensed matter pump-probe experiments.
