TITLE: Memory and Plasticity in Amorphous Solids ABSTRACT: While we are all familiar with retaining information in a computer or our minds, memory is an essential quality of many more non-equilibrium systems around us. We consider what information is stored in the arrangement of the particles in a 2D solid adsorbed at an oil-water interface. […]
Scanning time-resolved optical studies on Kagome superconductors The kagome lattice provides a fascinating playground to study geometrical frustration, topology and strong correlations. The newly discovered kagome metals AV3Sb5 (A = K, Rb, Cs) exhibit exotic phases including charge density waves (CDWs) and superconductivity. In our study, we perform scanning birefringence and circular dichroism (CD) microscopy on CsV3Sb5. The scanning […]

TITLE: Optics with a Twist for Material Characterization ABSTRACT: Optical wavefront shaping (WFS) involves the ability to manipulate light fields both spatially and temporally. It has largely been enabled by the availability of spatial light modulators (SLM). SLMs are used to create arbitrarily complex light fields and also provide means to manipulate the funda- mental […]

TITLE: Spin: stem-cell for emergence in quantum materials. ABSTRACT: 2025 is the centenary of quantum mechanics making this a good time to reflect on the past as a springboard for the bold research that the 21st century community of physicists can aspire to. One of the unexpected discoveries of Quantum Mechanics is Spin, a concept introduced […]
Host: Jazzmin Victorin Title: “Emergent metallicity and superconductivity at oxide heterointerfaces” Abstract: Perovskite-structured complex oxides exhibit a diverse array of physical properties, including magnetism, superconductivity, ferroelectricity, and metal-insulator transitions. The electronic, structural, and magnetic interactions at interfaces formed between crystalline, atomically-thin layers of these materials lead to the emergence of novel phases. Advances in the […]
Title: Polymer models for the prediction of 3D structure and transcription in human chromatin, Talk abstract: Transcription is a fundamental cellular process, and the first step of gene expression. In human cells, it depends on the binding to chromatin of various proteins, including RNA polymerases and numerous transcription factors (TFs). Observations indicate that these proteins […]

Title: Dynamic Jahn-Teller effect and a multi-polar order in 5d double-perovskites, The properties of strongly correlated systems have been at the forefront of scientific research for many decades. Typically focused on 3d transition metal compounds, it was often enough to consider only two relevant energy scales, the hopping integral and on-site Coulomb repulsion. In recent […]

TITLE: Quantum Control of Quantum Materials, ABSTRACT: Coherently engineering quantum states with light is a key frontier in the control of quantum materials. Over the last two decades, ultrafast lasers have revealed a variety of emergent topological, magnetic, and superconducting states in quantum materials driven far from equilibrium. Early experiments mainly adopted incoherent excitation strategies, […]
