• Abstract: Using the complex scaling and the stabilization method combined with the stochastic variational approach, we have shown that there are narrow resonance states in two-dimensional three particle systems of electrons and holes interacting via screened Coulomb interaction. These resonances are loosely bound systems of excited state excitons with a third particle circling around them. Recent experimental studies of excited state trions might be explained and identified by these resonant states.

  The electronic and emission properties of correlated multi-particle states are studied theoretically using GaAs/AlGaAs quantum dots. The convergence of the calculated energies and radiative lifetimes of Coulomb correlated exciton, biexciton, positive and negative trions to experimentally observed values is reached. It is proposed that in real experiments the neglected electron-electron and hole-hole exchange interactions are emitted as acoustic phonons.

• Realizing Topological Superconductivity in Tunable Bose-Fermi Mixtures with Transition Metal Dichalcogenide Heterostructures [0.0]
  We propose to engineer Bose-Fermi mixtures by coupling inter-layer excitons to doped charges in a trilayer structure. Their interactions are determined by the inter-layer trion, whose spin-selective nature allows excitons to mediate an attractive interaction between charge carriers of only one spin species. Remarkably, we find that this causes the system to become unstable to topological p+ip superconductivity at low temperatures.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

We explore electrostatic dipolar interactions that emerge, when two atoms are simultaneously excited to high-lying electronic states, so-called Rydberg states. This highlights the potential of Rydberg tweezer arrays for the study of molecular phenomena at exaggerated length scales.

  Hybrid quantum systems in the ultrastrong, and even more in the deep-strong, coupling regimes can exhibit exotic physical phenomena. We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator. This result opens a way to experimentally explore the novel quantum-vacuum effects emerging in the deep-strong coupling regime.

We propose our system as a versatile platform for the exploration of entangled multi-qubit physics.

  We propose applying time-dependent photo-emission spectroscopy, an established tool in solid state systems, in cold atom quantum simulators.

The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.
