Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC-BCS Crossover. [PDF]
Adv Sci (Weinh)This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Emerging 2D Materials with Nonparabolic Bands for Ultrafast Photonics
Small Science, Volume 3, Issue 10, October 2023., 2023 Materials with nonparabolic bands focus on different applications in ultrafast photonics, such as ultrafast carrier dynamics and nonlinear optical response. Linear dispersive Dirac bands have massless electrons like a photon, while nondispersive flat bands host electrons with an infinite mass.

Natural Sciences, Volume 3, Issue 3, July 2023., 2023 Roy Glauber displaying a poster with the gist of his theory of optical coherence in his own handwriting. Abstract We recount the life, work, and legacy of the theoretical physicist Roy Glauber (1925–2018). Admitted to Harvard at age 16, called upon to participate in the Manhattan Project at age eighteen, and appointed to the Harvard Physics faculty at ...

Advanced Photonics Research, Volume 3, Issue 7, July 2022., 2022 Stabilizing multidimensional solitons is challenging as critical and supercritical collapse problems arise. Two powerful ultracold atoms techniques, optical lattice and Feshbach resonance, are combined to address theoretically and numerically the formation and dynamics stability of 3D nonlinear localized gap modes of diverse types, including matter ...

Doublon Production in Correlated Materials by Multiple Ion Impacts
physica status solidi (b), Volume 259, Issue 4, April 2022., 2022 The formation of doublons (bound electron pairs) in correlated graphene‐type nanostructures following proton impacts is studied. The authors focus on the dependence of the energy and doublon number on the time interval between ion impacts and on the impact point. The simulations are done utilizing the recently developed G1–G2 scheme.

Löwdin's symmetry dilemma within Green functions theory for the one‐dimensional Hubbard model
Contributions to Plasma Physics, Volume 62, Issue 2, February 2022., 2022 Abstract The energy gap of correlated Hubbard clusters is well studied for one‐dimensional systems using analytical methods and density‐matrix‐renormalization‐group (DMRG) simulations. Beyond 1D, however, exact results are available only for small systems by quantum Monte Carlo.

Electron Number Density and Coherence Length of Boson‐Fermion Pair in HTSC
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 A Bose‐Einstein Condensate (BEC) of a nonzero momentum Cooper pair constitutes a composite boson or simply a boson. Previously, it has been shown that the quantum coherence of the two‐component BEC (boson and fermion condensates) is controlled by plasmons where <1% of plasmon energy mediates the charge pairing but most of the plasmon energy is used to ...

Molecular Regimes in Ultracold Fermi Gases [PDF]
, 2009 The use of Feshbach resonances for tuning the interparticle interaction in ultracold Fermi gases has led to remarkable developments, in particular to the creation and Bose-Einstein condensation of weakly bound diatomic molecules of fermionic atoms.
