In the context of the production of sneutrinos through Hawking evaporation of
primordial black holes (PBH), we have studied soft leptogenesis in the Minimal
Supersymmetric Standard Model (MSSM) with heavy right handed neutrinos.

Diffusion across a concentration step: Strongly nonmonotonic evolution
into thermodynamic equilibrium

General Physics
Dynamical and statistical behavior of the ionic particles in dissolved salts
have long been known, but their hydration shells still raise unsettled
questions. We engineered a ``diffusion tunnel diode" that is structurally
analogous to the w...

Let Y3,2 be the 3-graph with two edges intersecting in two vertices. We
prove that every 3-graph H on n vertices with at least max{(34αn),(3n)−(3n−αn)}+o(n3)
edges co...

Most control synthesis methods under temporal logic properties require a
model of the system, however, identifying such a model can be a challenging
task. In this work, we develop a direct data-driven control synthesis method
for temporal l...

Unanswered questions surrounding neutrinos have motivated investigations into
physics beyond the standard model (SM) of particle physics. In particular,
generalized neutrino interactions (GNI) provide a broader framework for
studying these ...

Computer Vision and Pattern Recognition
Vision-Language models (VLMs) have excelled in the image-domain -- especially
in zero-shot settings -- thanks to the availability of vast pretraining data
(i.e., paired image-text samples). However for videos, such paired data is not
as abu...

Payload grasping and transportation with quadcopters is an active research
area that has rapidly developed over the last decade. To grasp a payload
without human interaction, most state-of-the-art approaches apply robotic arms
that are atta...

Quantum Physics
A levitated nanomechanical oscillator under ultra-high vacuum (UHV) is highly
isolated from its environment. It has been predicted that this isolation leads
to very low mechanical dissipation rates. However, a gap persists between
predictio...
