摘要：
The study of quantum systems coupled to an environment plays a vital role in how we measure temperatures of the coldest and hottest matter in the universe. The strategy relies on introducing impurities into the system of interest and on observing how these probe particles evolve towards or in equilibrium with their surroundings, from which we may in turn deduce the thermal properties of that environment. Originally studied in the context of condensed matter physics, open quantum systems nowadays provide a common language to research spanning multiple orders of magnitude in temperature, ranging from Bose Einstein condensates made of ultracold atoms to the Quark-Gluon plasma created in ultra-relativistic collisions of heavy ions. This talk builds a bridge from polaron impurities in the former to quarkonium particles in the latter as two manifestations of quantum Brownian motion, a phenomenon ideally described by open quantum systems.

摘要：
In my talk I will discuss our recent work in studying the prospects to look for Dark Mater in Gravitational Wave Detectors using KAGRA as example. Interestingly, these detectors can probe a parameter region inaccessible to conventional Dark Matter direct searches. If time allows I will also comment on some other peoples work looking for a different kind of dark matter in gravitational wave detectors.

摘要：
Nonrelativistic bound states lie at the core of quantum physics,
permeating the fabric of nature across diverse realms, spanning particle
to nuclear physics, and from condensed matter to astrophysics. These
systems are pivotal in addressing contemporary challenges at the forefront
of particle physics. Characterized by distinct energy scales, they serve
as unique probes of complex environments. Historically, their
incorporation into quantum field theory was fraught with difficulty until
the emergence of nonrelativistic effective field theories (NREFTs).
In this colloquium, we delve into the construction of a potential NREFT
(pNREFT),a framework that directly tackles bound state dynamics
reimagining quantum mechanics from field theory. Focusing on heavy
quarkonia, pNRQCD facilitates systematic definitions and precise
calculations for high-energy collider observables. At the cutting edge, we
investigate nonrelativistic bound states in intricate environments, like
the newly discovered exotics X, Y, Z above the strong decay threshold and
the behavior in out-of-equilibrium scenarios, such as quarkonium
suppression in a Quark Gluon Plasma or dark matter interactions in the
early universe. Our ability to achieve precision calculations and control
strongly interacting systems is closely linked to bridging perturbative
methods with nonperturbative tools, notably numerical lattice gauge
theories.

摘要：

Understanding how external stimuli, such as electric field, mechanical strain, and light, induce dynamic changes in the physical properties of complex material systems is a central challenge in condensed matter physics. Systems like complex oxides, heterostructures, and 2D materials exhibit emergent phenomena—such as ferroelectricity, magnetism, and ultrafast photovoltaic effects—that arise from intricate couplings among electronic, structural, and magnetic degrees of freedom. These phenomena provide a rich platform for exploring fundamental physics and offer pathways to novel device applications. However, the underlying mechanisms driving these nanoscale stimulus dynamics and their connection to mesoscale behaviors remain elusive.
This presentation investigates an integrated approach that combines scanning probe microscopy (SPM) and phase-field modeling to uncover the physics governing these dynamic processes. SPM techniques deliver nanoscale resolution, enabling detailed characterization of domain evolution, spatial variations in conductivity, elastic moduli, and carrier dynamics under external stimuli. Complementary phase-field modeling captures the underlying physical principles linking nanoscale interactions to mesoscale phenomena, including domain wall dynamics, polarization switching, and strain-mediated coupling effects. Together, these methods enable the prediction and design of emergent properties, such as non-volatile domain switching and ultrafast photovoltaic responses, in ferroic and phase diverse systems.
Integrating experimental and theoretical methodologies advances our understanding of the mechanisms governing complex material systems under external stimuli. These findings not only deepen our knowledge of condensed matter physics but also open new opportunities to harness emergent phenomena for high-speed, high-density, and energy-efficient devices. Building on these insights, the presentation will outline future directions to expand these interdisciplinary approaches, with a particular focus on uncovering novel physics in strongly correlated and low-dimensional systems.
