01/09/2024: Aidan’s manuscript up on arXiv

Congratulations to lead-author Aidan Sudler, who finished a really cool work on driven generalized Rayleigh-van der Pol oscillators, just before heading off to Denmark for a semester abroad. The manuscript can be found here. The abstract reads: “Driven classical self-sustained oscillators have been studied extensively in the context of synchronization. Using the master equation, this work considers the classically driven generalized quantum Rayleigh-van der Pol oscillator, which is characterized by linear dissipative gain and loss terms as well as three non-linear dissipative terms. Since two of the non-linear terms break the rotational phase space symmetry, the Wigner distribution of the quantum mechanical limit cycle state of the undriven system is, in general, not rotationally symmetric. The impact of the symmetry-breaking dissipators on the long-time dynamics of the driven system are analyzed as functions of the drive strength and detuning, covering the deep quantum to near-classical regimes. Phase localization and frequency entrainment, which are required for synchronization, are discussed in detail. We identify a large parameter space where the oscillators exhibit appreciable phase localization but only weak or no entrainment, indicating the absence of synchronization. Several observables are found to exhibit the analog of the celebrated classical Arnold tongue; in some cases, the Arnold tongue is found to be asymmetric with respect to vanishing detuning between the external drive and the natural oscillator frequency.” Really nice work — congratulations to undergraduate student Aidan Sudler and former graduate student Jugal Talukdar!

July 25, 2023: Paper out in Physical Review Letters

Doerte had the pleasure to work with lead-author Xin-Yuan Gao and his advisor Yangqian Yan from the Chinese University of Hong Kong on an exciting project that just appeared in PRL. Here is a bit of context: In a recent groundbreaking experiment, scientists cooled a fermionic KRb molecular gas to quantum degeneracy, marking a significant milestone in ultracold molecule research. Unexpectedly, the experiment observed the suppression of the two-body loss rate in the deep quantum degenerate regime. We develop a simple yet robust first-principle theory, which not only explains the puzzling experimental observation but also opens the door for several new directions in ultracold atomic and molecular gases with anisotropic p-wave interactions. Building on previous work from the literature, our investigation showcases the pivotal role of the “p-wave contact,” linking the dynamic two-body loss rate with the thermodynamics of a weakly interacting, single-component Fermi gas. The consistent incorporation of microscopic few-body physics into quantifiable quantum statistical mechanics over a wide temperature range, from the deep quantum degenerate to the non-degenerate regime, allowed us to successfully reproduce the puzzling experimental observation of the “quantum suppression of the loss rate”, shedding light on its underlying mechanisms. Our conclusions provide vital guidance for future experiments and hold potential for a range of other applications.

Call for Nominations for 2021 Faddeev Medal

We are pleased to announce the call for nominations for the 2021 “Faddeev Medal” 
Prize. We are seeking nominations of scientists who have advanced the field of 
few-body physics significantly, either through ground-breaking research or due to 
crucial progress achieved over the course of their career.

The Faddeev medal was inaugurated in 2016 by the Topical Group on Few-Body Systems & Multiparticle Dynamics (GFB) of the American Physical Society and the European Research Committee on Few-Body Problems in Physics (ERCFBP) to recognize distinguished achievements in few-body physics. It is named in honor of distinguished scientist Ludwig D. Faddeev (1934-2017). It was awarded for the first time in 2018 to Vitaly Efimov and Rudi Grimm for “the theoretical discovery of a series of weakly-bound three-body quantum states known as Efimov states” and “in recognition of his ground-breaking experiments confirming the Efimov effect”, respectively.

The nomination deadline for the 2021 “Faddeev Medal” is April 15, 2021. See this link for more details.
