DESCRIPTION:Speakers: Gerben Oling ()\nIt has been known for some time tha
t there exists a self-consistent limit of string theory with a non-relativ
istic spectrum. Over the last few years\, many aspects of the resulting no
n-relativistic string theory have been developed\, including its coupling
to curved non-Lorentzian backgrounds. In this talk\, by means of the anal
ogous constructions for non-relativistic point particles\, I will attempt
to give an accessible introduction to some of the foundations of these rec
ent developments in non-relativistic string theory. I will also summarize
related results on the bulk interpretation of Spin Matrix limits in terms
of strings on AdS\, which give rises to strings with non-Lorentzian worlds
heets.\n\nhttps://indico.ph.ed.ac.uk/event/233/contributions/2198/

DESCRIPTION:Speakers: Ziqi Yan ()\nI will talk about some recent progress
on non-perturbative SL(2\,Z) duality in nonrelativistic string theory\, wh
ich is a self-contained string theory that has a string spectrum with a Ga
lilean invariant dispersion relation. I will show that the SL(2\,Z) dualit
y in this string theory exhibits intriguing new structure. This study prov
ides a precursor towards realizing novel U-duality relations between nonre
lativistic and discrete light-cone quantization (DLCQ) string/M-theory\, w
here DLCQ appears in non-perturbative approaches to quantum field theory a
nd string/M-theory\, such as in matrix model.\n\nhttps://indico.ph.ed.ac.u

SUMMARY:Non-relativistic massive higher-spin modes in the Fractional Quant

DESCRIPTION:Speakers: Giandomenico Palumbo ()\nIt is quite well known that
quantum area-preserving diffeomorphisms play a key role in the fractional
quantum Hall states (FQHs) and explain\, for instance\, the incompressibi
lity of the quantum Hall fluids. Moreover\, quantum area-preserving diffeo
morphisms in two space dimensions are naturally encoded in the so-called G
irvin-MacDonald-Plazman (GMP) algebra or in its dual version known as W_{\
\infinity} algebra. In this talk\, firstly I will introduce an effective-f
ield-theory approach that shows the relation between the GMP algebra and t
he emergence of a non-relativistic massive spin-2 mode in the bulk state o
f FQHs through the existence of a nematic order. The corresponding nematic
order parameter is nothing but a symmetric rank-2 tensor that can be natu
rally identified with an emergent metric tensor. Secondly\, I will gener
alize this approach by showing how higher-rank symmetric tensors and their
corresponding non-relativistic massive higher-spin modes\, which should n
aturally emerge from quantum area-preserving diffeomorphisms\, can be inde
ed introduced and analyzed by considering generalized nematic FQHs. It rem
ains an open question how and if these modes can be derived from a suitabl
e non-relativistic version of linearized higher-spin gravity.\n\nhttps://i

DESCRIPTION:Speakers: Jay Armas ()\nI will discuss a new hydrodynamic theo
ry using Aristotelian geometry that accounts for pinning\, phase\, and mom
entum relaxation effects due to translational disorder\, diffusion due to
the presence of interstitials and vacancies\, and strain relaxation due to
plasticity and dislocations. I will focus on signatures of plastic deform
ations in electronic crystals and show that proliferation of dislocations
de-pins the spatially resolved conductivity until the crystal melts\, afte
r which point a new phase of a pinned electronic liquid emerges. The frame
work is applicable to a large class of physical systems including electron
ic Wigner crystals\, multicomponent charge density waves\, metals and ordi
nary crystals.\n\nhttps://indico.ph.ed.ac.uk/event/233/contributions/2195/

DESCRIPTION:Speakers: Niels Obers ()\nI will review Newton-Cartan gravity
with an emphasis on recent developments\, including the covariant\, off-sh
ell large speed of light expansion of general relativity. Depending on the
matter content\, this expansion either leads to Newton-Cartan geometry wi
th absolute time or to Newton-Cartan geometry with non-relativistic gravit
ational time dilation effects. The latter shows that non-relativistic grav
ity includes a strong field regime and goes beyond Newtonian gravity. Earl
ier work on Newton-Cartan geometry will be briefly discussed\, after which
we turn to modern approaches\, which include the gauging of the Bargmann
algebra\, as well as a new notion of `type II' notion of Newton-Cartan geo
metry which arises from the large speed of light (c) expansion of General
Relativity. Finally\, I will mention matter couplings\, solutions and od
d powers in 1/c\, as well as a summary of related topics.\n\nhttps://indic

content of the model. We demonstrate our method for particles\, strings\,

puzzles that have fueled their study. I will focus particularly on the que
stion of UV/IR mixing and how it affects renormalization.\n\nhttps://indic

DESCRIPTION:Speakers: Akash Jain ()\nSymmetries and their breaking pattern
s are a valuable tool in physics for classifying and describing phases of
matter. In recent years\, a new generalised notion of symmetries has emerg
ed\, dubbed "higher-form symmetries"\, where the associated conserved char
ges are carried by higher-dimensional objects like strings and surfaces\,
instead of the usual point-like particles. In this talk\, I will give a br
ief overview of higher-form symmetries and their spontaneous and explicit
breaking patterns. In particular\, the explicit breaking of higher-form sy
mmetries is associated with the emergence of topological defects in many-b
ody systems. We will outline a new hydrodynamic framework for systems with
(approximate) higher-form symmetries and use this to study transitions be
tween topological phases of matter. This includes the melting phase transi
tion in smectic \ncrystals\, the plasma phase transition from polarised ga
ses to magnetohydrodynamics\, the superfluid to neutral fluid phase transi
tion\, and the Meissner effect in superconductors\, among many others. The
talk will be based on: https://arxiv.org/abs/2301.09628.\n\nhttps://indic

DESCRIPTION:Speakers: Silvia Penati ()\nI will discuss quantum properties
of galilean N=2 supersymmetric theories in d =2+1\, primarily focusing on
the non-relativistic version of the Wess-Zumino model and SuperQED. Compar
ed with their relativistic cousins\, these models exhibit very different b
ehavior. The non-relativistic Wess-Zumino model is one-loop exact\, as a c
onsequence of robust non-renormalisation theorems. The non-relativistic el
ectrodynamics is featured by an infinite number of marginal couplings that
turn on along the RG flows. Superconformal invariance is preserved in cor
respondence of a non-trivial conformal manifold of fixed points where the
theory is gauge-invariant and interacting.\n\nhttps://indico.ph.ed.ac.uk/e
