Abstract Quantum thermometry is the science of estimating or measuring the temperature, using quantum systems. A common physical model of quantum thermometry is the collisional model, in which the temperature is estimated from quantum systems that interact with the thermal bath (which defines the temperature) in a relatively short timescale, and hence, out of thermal equilibrium with the bath. In this work, we study quantum thermometry from a multiparameter perspective, where in addition to the temperature parameter, the interaction strength in the collisional model is treated as an unknown as well.

Abstract Carbohydrates are among the most structurally diverse biomolecules in biology. Unlike nucleic acids and proteins, their structures are not directly specified by a genetic template. Instead, glycan structures emerge from the coordinated activities of carbohydrate-active enzymes, substrate availability, and cellular context. How such non-template-directed processes generate highly defined structures, and how these structures are translated into biological function, remains a fundamental challenge in glycoscience. Our research aims to decode this “glycocode” by integrating chemoenzymatic, synthetic biology, and analytical approaches. One major focus is protein lycosylation. We develop chemoenzymatic glycoengineering strategies to generate glycoproteins with precisely defined glycan structures, allowing individual glycoforms to be systematically compared. Using this approach, we investigate how specific glycan features influence molecular recognition, receptor interactions, and immune effector functions, thereby establishing direct relationships between glycan structure and biological activity. A second focus addresses how complex polysaccharide structures are generated in the absence of a template. Although polysaccharide biosynthesis is non-template-directed, the resulting structures are clearly non-random. Structural profiling of xyloglucans from more than 200 plant species revealed conserved motifs and distinct structural forms associated with ancestral, intermediate, and structurally reduced patterns, providing evidence for the evolutionary diversification of polysaccharide structure. Likewise, analyses of bacterial mixed-linkage β-glucans (MLGs) revealed substantial structural variation while retaining characteristic linkage patterns. To understand how such patterns are generated, we investigate the membrane-associated glycosyltransferases responsible for MLG biosynthesis. Through synthetic biology, enzyme engineering, site-directed mutagenesis, biochemical and biophysical characterization, and advanced analytical approaches including Logically Derived Sequence Tandem Mass Spectrometry (LODES/MSⁿ), we examine how enzyme sequence, regulatory elements, and cellular environment control polysaccharide production,linkage distribution, and overall polysaccharide structure. By moving from comparative structural profiling to mechanistic dissection and defined glycoforms, we aim to uncover the molecular rules that govern how carbohydrate structures are generated and how they influence biological function. Ultimately, this work seeks to understand how structural information is written into glycans, the molecular basis of the glycocode.

Abstract Spin- and angle-resolved photoemission spectroscopy (spin-ARPES) is widely used to determine the spin polarization of electronic states. In this seminar, I will discuss two recent developments in spin-ARPES that go beyond conventional spin-polarization measurements. First, I will introduce a phase-resolved approach based on spin interference [1-3]. In spin-orbit-coupled systems, coherent superposition of different ptical transition channels can rotate the photoelectron spin. By measuring the full three-dimensional spin vector, the relative phase between these channels can be extracted, allowing spin-ARPES to be viewed as an nterferometric probe of the complex photoemission response.Second, I will present our recent development of spin-ARPES [4] combined with pump-probe technique at HiSOR, which combines femtosecond optical excitation with three-dimensional spin detection to investigate transient spin-polarized states and ultrafast spin dynamics.Together, these studies illustrate how spin-ARPES can provide information beyond conventional spin-polarization measurements.
