SUMMARY:Kirill NOURSKI (University of Iowa\, USA)
DESCRIPTION:What the insula hears and does : Insights from human intracranial electrophysiology\nRésumé : \nThe human insula is known to be involved in auditory processing\, though its detailed response properties remain elusive. Intracranial recordings in human neurosurgical patients provide a unique opportunity to characterize the functional properties of the human insula with high spatiotemporal resolution. Local field potential recordings reveal that posterior insula (InsP) is characterized by larger broadband gamma (30-150 Hz) responses to monosyllabic words compared to anterior insula (InsA). Both subdivisions of the insula generate evoked responses to novel sounds. Single neurons within InsP and\, to a lesser extent\, InsA\, respond to simple sounds in the absence of a behavioral context. InsP and InsA share similar res9ng state functional connectivity profiles with limbic structures. InsP is more closely linked to activity propagated from early auditory cortex\, while InsA is more tightly coupled with prefrontal\, anterior temporal regions and the amygdala. Clinical case studies identify language and music perception deficiencies associated with insula lesions. Finally\, single unit recordings during emergence from general anesthesia reveal a temporal dissociation between reactivation of limbic structures and the insula\, the laPer marking the transition to connected consciousness and the capacity to act on commands. Together\, these results begin to characterize the insula’s place in the auditory hierarchy\, with implications ranging from sensory processing to conscious awareness of our surroundings. \n_ \nContact : julien.bastin@univ-grenoble-alpes.fr \n  \n

SUMMARY:Alexandra COLIN (CEA-Irig/LPCV)
DESCRIPTION:Dynamics and Scaling of Competitive Actin Architectures\nRésumé : \n\nCells constantly experience environmental changes requiring a fast adaptation of their different actin structures. However\, the mechanisms governing the size and dynamics of these multiple actin structures remain unknown. Decoupling the various parameters that would provide a complete understanding of these mechanisms is very complicated in a cellular context. This is why we have developed a bottom-up approach to identify the key molecular mechanisms that determine the size and coexistence of multiple competing actin architectures. We used a reconstituted system consisting of purified proteins and substrates to localize actin polymerization in microwells\, enabling us to work with a limited number of components. With this system\, we reconstituted several dynamic actin architectures\, competing for a limited pool of protein\, over a period of multiple hours. This allowed us to gain key insights into physiological functions related to actin turnover. I will show how we used this system to study the limits of scaling in dynamic structures\, as well as the limits of coexistence in actin networks under resource-limited conditions. Finally\, I will show how we can recapitulate these results in a complementary cellular system\, in which we have demonstrated that an increase in spreading area leads to a decrease in overall turnover\, due to a predominance of structures with low turnover.​​​​​\n​\n\n\n\nLes séminaires et soutenances sont ouverts à tous\, notez toutefois que l’accès au campus EPN nécessite un avis de rendez-vous.

SUMMARY:Benjamin LENZ (IMPMC)
DESCRIPTION:Spectroscopic signatures of spin-polarons in quasi two-dimensional correlated materials\nRésumé : \nThe motion of a single hole in a two-dimensional antiferromagnet can lead to the formation of a low-energy quasiparticle\, a so-called spin-polaron\, which amounts to a bound state of the doped hole and a spin flip. In this talk\, I will first introduce the notion of spin-polarons and then discuss spectroscopic signatures of this quasiparticle at the example of two different material classes which both host quasi two-dimensional low-energy physics in their correlated electronic structure.\nIllustrated by the Na-doped oxychloride Ca2CuO2Cl2\, we will see how the spin-polaron gives rise to “kink” and “waterfall” features in the spectral function of hole-doped cuprates. Employing a numerical workflow comprising density functional theory and cluster dynamical mean-field theory\, we will discuss these features in comparison to measurements obtained from angle-resolved photoemission spectroscopy. As a second example\, we will see that spin-polaron physics is also relevant in two prototypical iridates\, (Ba\,Sr)2IrO4\, which host an exotic spin-orbital entangled jeff=1/2 ground state. In particular\, the characteristic two-peak structure of their optical absorption and optical conductivity curves will be revisited and interpreted in the light of these coherent low-energy quasiparticles. \nB.

SUMMARY:Luis Alberto RAZO LOPEZ (Institut Langevin\, Paris)
DESCRIPTION:Phase retrieval based on intensity-only spatiotemporal wavefront shaping\nRésumé : \nWe introduce a phase retrieval framework based solely on intensity measurements and intensity-only spatiotemporal modulation. Our approach leverages spatiotemporal wavefront shaping to encode phase information into temporally multiplexed intensity signals\, which are subsequently decomposed in the Fourier domain. We show that the resulting temporal harmonics correspond to spiral-phase–modulated speckle components\, enabling the retrieval of phase information without direct phase-sensitive detection. We derive the harmonic structure induced by a rotating angular aperture mask and demonstrate that each harmonic carries a distinct spiral phase and amplitude weighting governed by a sinc envelope. Based on this structure\, we develop an optimization-based reconstruction algorithm that retrieves both the unknown diffuser phase and system scaling without prior knowledge of the optical transfer function. Experimental results confirm accurate reconstruction of diffuser surfaces and aberration correction\, including refocusing through digital micromirror device (DMD)-induced distortions. \nContact : dorian.bouchet@univ-grenoble-alpes.fr

SUMMARY:Roger TORMO-QUERALT (Institute of Photonic Sciences (ICFO)\, Barcelona\, Spain)
DESCRIPTION:Carbon Nanotube Electromechanical Oscillators: where photons\, phonons and electrons meet\nRésumé : \nAchieving strong mechanical nonlinearities\, minimally invasive detection\, and control at the few-phonon level is a central challenge in the development of mechanical oscillators for quantum technologies\, including quantum information processing (1\,2)\, precision sensing (3)\, and tests of quantum mechanics (4\,5). In our group\, we aim to realize these capabilities using suspended carbon-nanotube mechanical oscillators coupled to electronic quantum dots. In this talk\, I will present results obtained with a device operating in the exotic dispersive ultrastrong-coupling regime (6\,7)\, where the interaction strength between a nanotube mechanical oscillator and a double-quantum-dot electronic two-level system (DQD-ETLS) exceeds the bare energy of the oscillator. In this regime\, we demonstrate a mechanical Kerr oscillator with an anharmonicity exceeding the state of the art for mechanical systems by four orders of magnitude (8). We read out the mechanical states using a superconducting cavity coupled to the square displacement (x²) of the oscillator (8)\, paving the way towards future quantum non-demolition (QND) cavity-based readout of mechanical Fock states (9). I will also show that the decay and decoherence rates of our ETLS charge qubit outperforms the current state of the art for 2DEG-based systems\, reaching the highest coherence values ever measured in a charge-based DQD-ETLS (10). \n1 A.

SUMMARY:Jonathan HOME (ETH Zürich)
DESCRIPTION:Scaling trapped-ion quantum computers\nRésumé : \nTrapped ions are among the most promising paths to realizing quantum computers\, having exhibited the highest fidelity gates and long coherence times. Scaling up will require the adoption of new technologies\, and can be facilitated by new approaches. In this talk I will describe recent work from our group in both directions. Firstly I will describe the use of integrated optics to deliver light to multiple zones of an ion trap chip in scalable manner\, and give an impression of the new types of control which might be enabled by this approach 1\,2\,3. I will then introduce a new concept for scaling trapped-ion quantum computers based on microfabricated Penning traps\, introducing flexible 2-dimensional ion transport while removing the need for high-voltage radio-frequency fields and thus improving compatibility with standardized chip fabrication 4\,5. We have used this to perform sensing of both static and oscillating magnetic and electric fields near the chip surface\, and more recently demonstrated multi-qubit gates and control of multi-dimensional arrays of ions. \n1 K.
