Finding a trajectory to
industry
|
|
(Host:
Hal Metcalf)
|
|
|
Learn
about how a
PhD
from the AMO
group here at
Stony Brook
found a career
in the
photonics
industry,
with some
interesting
tid-bits of
science mixed
in. Students considering
careers
outside of
academia are
encouraged
to attend.

| Emergent
quantum
optical
phenomena in
atomic arrays
|
|
(Host:
Dominik
Schneble)
|
|
|
Atomic
ensembles
constitute a
dominant
platform for
realizing
quantum
interfaces
between light
and matter. In
dense and
ordered
arrays,
interference
in photon
emission leads
to the
emergence of
correlated
states, with
very different
decay rates
and lifetimes.
I will give a
pedagogical
overview of
recent work on
collective
phenomena in
light-matter
interaction,
and focus on
our recent
proposal of
employing
one-dimensional
ordered arrays
as atomic
waveguides.
These arrays
support guided
modes that do
not decay into
free space
(i.e., are
subradiant)
and can be
harnessed to
mediate
tunable,
long-range
interactions
between
additional
``qubit''
atoms coupled
to the chain,
without need
for photonic
structures.
Moreover,
owing to the
two-level
nature of
atoms, these
waveguides are
intrinsically
quantum. In
contrast to
classical
waveguides,
where photons
do not
interact with
each other,
atomic
waveguides
display strong
non-linearities.
I will discuss
how
counter-propagating
photons
collide,
leading to
dissipation
and scattering
out of the
chain. This
tunable
non-linearity
opens the door
to the
exploration of
many-body
physics
between guided
photons and to
the
realization of
switches and
transistors at
the
single-photon
level.
