Gas-rich environments are ubiquitous in various scales, from
protoplanetary disks to star clusters and galaxies. Dynamics in
gas-rich environments are substantially different and give rise to
unique astrophysical phenomena, along with enhancing the...
The Navier–Stokes (NS) equations describe fluid dynamics through
a high-dimensional, nonlinear partial differential equations (PDEs)
system. Despite their fundamental importance, their behavior in
turbulent regimes remains incompletely understood...
The alpha disk model is widely used to describe the accretion
disk structures around supermassive black holes, even though it
cannot explain many observed properties of AGNs. Various
alternative models have been proposed including the ones
where...
Quantum condensed matter has traditionally focused on ground
states and equilibrium properties of spatially extended systems,
such as electrons in crystalline materials. However, the advent of
noisy-intermediate-scale-quantum (NISQ) devices has...
Informally, a quantum cellular automaton (QCA) describes some
discrete-time local dynamics of a quantum system. Formally, a
QCA is a *-automoprhism of the algebra of local operators.
Local quantum circuits provide one example of QCA, but the...
Powerful techniques have been developed in quantum field theory
that employ algebras of local operators, yet local operators cannot
create physical charged states in gauge theory or physical
nonzero-energy states in perturbative quantum gravity. ...
The so-called galaxy--halo connection is a vast topic concerning
how galaxies populate their host dark matter halos. I will
present some works we have made under this grand theme, including
(1) the detection of assembly bias signal with the help of...
AI progress is accelerating, and now the leaders expect
“artificial general intelligence” (AGI) in 2 to 3 years. While
difficult to believe, we must prepare for the possibility. We can
take some lessons from previous episodes in which computers...
Despite the undeniable success of the Large Hadron Collider
(LHC), Beyond the Standard Model (BSM) physics remains elusive. In
this talk, I will outline a multifaceted strategy to maximize
discovery potential at current and future high-energy...
The first structures of particle dark matter form by
gravitationally condensing out of the smooth mass distribution of
the early universe. This formation mechanism leaves these "prompt
cusps" with uniquely compact r^-1.5 density profiles and
links...
