text: "Persistent revivals recently observed in Rydberg atom simulators have challenged
our understanding of thermalization and attracted much interest to the concept
of quantum many-body scars (QMBSs). QMBSs are non-thermal highly excited eigenstates
that coexist with typical eigenstates in the spectrum of many-body Hamiltonians,
and have since been reported in multiple theoretical models, including the so-called
PXP model, approximately realized by Rydberg simulators. At the same time, questions
of how common QMBSs are and in what models they are physically realized remain
open. In this Letter, we demonstrate that QMBSs exist in a broader family of models
that includes and generalizes PXP to longer-range constraints and states with
different periodicity. We show that in each model, multiple QMBS families can
be found. Each of them relies on a different approximate \U0001D530\U0001D532(2)
algebra, leading to oscillatory dynamics in all cases. However, in contrast to
the PXP model, their observation requires launching dynamics from weakly entangled
initial states rather than from a product state. QMBSs reported here may be experimentally
probed using Rydberg atom simulator in the regime of longer-range Rydberg blockades."

text: We propose a new weak solution concept for (two-phase) mean curvature flow
which enjoys both (unconditional) existence and (weak-strong) uniqueness properties.
These solutions are evolving varifolds, just as in Brakke's formulation, but are
coupled to the phase volumes by a simple transport equation. First, we show that,
in the exact same setup as in Ilmanen's proof [J. Differential Geom. 38, 417-461,
(1993)], any limit point of solutions to the Allen-Cahn equation is a varifold
solution in our sense. Second, we prove that any calibrated flow in the sense
of Fischer et al. [arXiv:2003.05478] - and hence any classical solution to mean
curvature flow-is unique in the class of our new varifold solutions. This is in
sharp contrast to the case of Brakke flows, which a priori may disappear at any
given time and are therefore fatally non-unique. Finally, we propose an extension
of the solution concept to the multi-phase case which is at least guaranteed to
satisfy a weak-strong uniqueness principle.

text: We address two pressing questions in the theory of the Korteweg–de Vries (KdV)
equation. First, we show the uniqueness of solutions to KdV that are merely bounded,
without any further decay, regularity, periodicity, or almost periodicity assumptions.
The second question, emphasized by Deift, regards whether almost periodic initial
data leads to almost periodic solutions to KdV. Building on the new observation
that this is false for the Airy equation, we construct an example of almost periodic
initial data whose KdV evolution remains bounded, but fails to be almost periodic
at a later time. Our uniqueness result ensures that the solution constructed is
the unique development of this initial data.

text: 'Current numerical algorithms for simulating friction fall in one of two camps:
smooth solvers sacrifice the stable treatment of static friction in exchange for
fast convergence, and non-smooth solvers accurately compute friction at convergence
rates that are often prohibitive for large graphics applications. We introduce
a novel bridge between these two ideas that computes static and dynamic friction
stably and efficiently. Our key idea is to convert the highly constrained non-smooth
problem into an unconstrained smooth problem using logarithmic barriers that converges
to the exact solution as accuracy increases. We phrase the problem as an interior
point primal-dual problem that can be solved efficiently with Newton iteration.
We observe quadratic convergence despite the non-smooth nature of the original
problem, and our method is well-suited for large systems of tightly packed objects
with many contact points. We demonstrate the efficacy of our method with stable
piles of grains and stacks of objects, complex granular flows, and robust interlocking
assemblies of rigid bodies.'

text: 'We introduce a multi-material non-manifold mesh-based surface tracking algorithm
that converts self-intersections into topological changes. Our algorithm generalizes
prior work on manifold surface tracking with topological changes: it preserves
surface features like mesh-based methods, and it robustly handles topological
changes like level set methods. Our method also offers improved efficiency and
robustness over the state of the art. We demonstrate the effectiveness of the
approach on a range of examples, including complex soap film simulations with
thousands of interacting bubbles, and boolean unions of non-manifold meshes consisting
of millions of triangles.'

text: Physics simulation in computer graphics can bring triangle meshes into topologically
invalid states. The method in this thesis contributed to Heiss-Synak* and Kalinov*
et al. [2024] who devised a non-manifold hybrid surface tracker—a surface tracker
that repairs explicit non-manifold triangle meshes with the help of the implicit
domain. Specifically, this thesis provides an algorithm for filling the holes
that are left after removing problematic parts of the mesh.

text: Mechanisms for suppressing thermalization in disorder-free many-body systems,
such as Hilbert space fragmentation and quantum many-body scars, have recently
attracted much interest in foundations of quantum statistical physics and potential
quantum information processing applications. However, their sensitivity to realistic
effects such as finite temperature remains largely unexplored. Here, we have utilized
IBM's Kolkata quantum processor to demonstrate an unexpected robustness of quantum
many-body scars at finite temperatures when the system is prepared in a thermal
Gibbs ensemble. We identify such robustness in the PXP model, which describes
quantum many-body scars in experimental systems of Rydberg atom arrays and ultracold
atoms in tilted Bose--Hubbard optical lattices. By contrast, other theoretical
models which host exact quantum many-body scars are found to lack such robustness,
and their scarring properties quickly decay with temperature. Our study sheds
light on the important differences between scarred models in terms of their algebraic
structures, which impacts their resilience to finite temperature.

text: In 1998 Burago and Kleiner and (independently) McMullen gave examples of separated
nets in Euclidean space which are non-bilipschitz equivalent to the integer lattice.
We study weaker notions of equivalence of separated nets and demonstrate that
such notions also give rise to distinct equivalence classes. Put differently,
we find occurrences of particularly strong divergence of separated nets from the
integer lattice. Our approach generalises that of Burago and Kleiner and McMullen
which takes place largely in a continuous setting. Existence of irregular separated
nets is verified via the existence of non-realisable density functions ρ:[0,1]d→(0,∞).
In the present work we obtain stronger types of non-realisable densities.

text: We study systems of nonlinear partial differential equations of parabolic
type, in which the elliptic operator is replaced by the first-order divergence
operator acting on a flux function, which is related to the spatial gradient of
the unknown through an additional implicit equation. This setting, broad enough
in terms of applications, significantly expands the paradigm of nonlinear parabolic
problems. Formulating four conditions concerning the form of the implicit equation,
we first show that these conditions describe a maximal monotone p-coercive graph.
We then establish the global-in-time and large-data existence of a (weak) solution
and its uniqueness. To this end, we adopt and significantly generalize Minty’s
method of monotone mappings. A unified theory, containing several novel tools,
is developed in a way to be tractable from the point of view of numerical approximations.

text: The brain is one of the largest and most complex organs and it is composed
of billions of neurons that communicate together enabling e.g. consciousness.
The cerebral cortex is the largest site of neural integration in the central nervous
system. Concerted radial migration of newly born cortical projection neurons,
from their birthplace to their final position, is a key step in the assembly of
the cerebral cortex. The cellular and molecular mechanisms regulating radial neuronal
migration in vivo are however still unclear. Recent evidence suggests that distinct
signaling cues act cell-autonomously but differentially at certain steps during
the overall migration process. Moreover, functional analysis of genetic mosaics
(mutant neurons present in wild-type/heterozygote environment) using the MADM
(Mosaic Analysis with Double Markers) analyses in comparison to global knockout
also indicate a significant degree of non-cell-autonomous and/or community effects
in the control of cortical neuron migration. The interactions of cell-intrinsic
(cell-autonomous) and cell-extrinsic (non-cell-autonomous) components are largely
unknown. In part of this thesis work we established a MADM-based experimental
strategy for the quantitative analysis of cell-autonomous gene function versus
non-cell-autonomous and/or community effects. The direct comparison of mutant
neurons from the genetic mosaic (cell-autonomous) to mutant neurons in the conditional
and/or global knockout (cell-autonomous + non-cell-autonomous) allows to quantitatively
analyze non-cell-autonomous effects. Such analysis enable the high-resolution
analysis of projection neuron migration dynamics in distinct environments with
concomitant isolation of genomic and proteomic profiles. Using these experimental
paradigms and in combination with computational modeling we show and characterize
the nature of non-cell-autonomous effects to coordinate radial neuron migration.
Furthermore, this thesis discusses recent developments in neurodevelopment with
focus on neuronal polarization and non-cell-autonomous mechanisms in neuronal
migration.

text: This study advances mechanistic interpretation of predictability challenges
in hydro-geomorphology related to the role of soil moisture spatial variability.
Using model formulations describing the physics of overland flow, variably saturated
subsurface flow, and erosion and sediment transport, this study explores (1) why
a basin with the same mean soil moisture can exhibit distinctly different spatial
moisture distributions, (2) whether these varying distributions lead to non-unique
hydro-geomorphic responses, and (3) what controls non-uniqueness in relation to
the response type. Two sets of numerical experiments are carried out with two
physically-based models, HYDRUS and tRIBS+VEGGIE+FEaST, and their outputs are
analyzed with respect to pre-storm moisture state. The results demonstrate that
distinct spatial moisture distributions for the same mean wetness arise because
near-surface soil moisture dynamics exhibit different degrees of coupling with
deeper-soil moisture and the process of subsurface drainage. The consequences
of such variations are different depending on the type of hydrological response.
Specifically, if the predominant runoff response is of infiltration excess type,
the degree of non-uniqueness is related to the spatial distribution of near-surface
moisture. If runoff is governed by subsurface stormflow, the extent of deep moisture
contributing area and its “readiness to drain” determine the response characteristics.
Because the processes of erosion and sediment transport superimpose additional
controls over factors governing runoff generation and overland flow, non-uniqueness
of the geomorphic response can be highly dampened or enhanced. The explanation
is sediment composed by multi-size particles can alternate states of mobilization
or surface shielding and the transient behavior is inherently intertwined with
the availability of mobile particles. We conclude that complex nonlinear dynamics
of hydro-geomorphic processes are inherent expressions of physical interactions.
As complete knowledge of watershed properties, states, or forcings will always
present the ultimate, if ever resolvable, challenge, deterministic predictability
will remain handicapped. Coupling of uncertainty quantification methods and space-time
physics-based approaches will need to evolve to facilitate mechanistic interpretations
and informed practical applications.

text: We consider the Gross–Pitaevskii equation on R^4 and the cubic-quintic nonlinear
Schrödinger equation (NLS) on R^3 with non-vanishing boundary conditions at spatial
infinity. By viewing these equations as perturbations to the energy-critical NLS,
we prove that they are globally well-posed in their energy spaces. In particular,
we prove unconditional uniqueness in the energy spaces for these equations.
