Non-Lorentzian Supergravity from Matrix Theory
Dawid Maskalaniec, Ziqi Yan, Utku Zorba
It was recently shown that the decoupling limits leading to matrix (gauge) theories on D-branes give rise to non-Lorentzian target space geometries. Perturbatively, matrix theory d…
Quantization of Carrollian fermions
Ertuğrul Ekiz, Emre Onur Kahya, Utku Zorba
We provide the first example of interacting quantized Carrollian Dirac fermions and investigate their discrete symmetries, including charge conjugation (C), parity (P), and time re…
Supersymmetric Carroll Galileons in Three Dimensions
Utku Zorba, Ilayda Bulunur, Oguzhan Kasikci +3
We present the first example of an interacting Carroll supersymmetric field theory with both temporal and spatial derivatives, belonging to the Galileon class, where the non-linear…
Carrollian Supersymmetry and SYK-like models
Oguzhan Kasikci, Mehmet Ozkan, Yi Pang +1
This work challenges the conventional notion that in spacetime dimension higher than one, a supersymmetric Lagrangian invariably consists of purely bosonic terms, purely fermionic…
Non-Lorentzian IIB Supergravity from a Polynomial Realization of SL(2,R)
Eric Bergshoeff, Kevin T. Grosvenor, Johannes Lahnsteiner +2
We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find that the bosonic field content is…
Branched SL(2,Z) Duality
Eric Bergshoeff, Kevin T. Grosvenor, Johannes Lahnsteiner +2
We investigate how SL(2,Z) duality is realized in nonrelativistic type IIB superstring theory, which is a self-contained corner of relativistic string theory. Within this corner, w…
Non-Relativistic and Ultra-Relativistic Scaling Limits of Multimetric Gravity
Ertuğrul Ekiz, Oguzhan Kasikci, Mehmet Ozkan +2
We present a method of contraction that can be applied to re-construct the recent extended non-relativistic and ultra-relativistic algebras as well as corresponding action principl…
Carrollian and Non-relativistic Jackiw-Teitelboim Supergravity
Lucrezia Ravera, Utku Zorba
We present non- and ultra-relativistic Jackiw-Teitelboim (JT) supergravity as metric BF theories based on the extended Newton-Hooke and extended AdS Carroll superalgebras in two sp…
Three-Dimensional Higher-Order Schrödinger Algebras and Lie Algebra Expansions
Oguzhan Kasikci, Nese Ozdemir, Mehmet Ozkan +1
We provide a Lie algebra expansion procedure to construct three-dimensional higher-order Schrödinger algebras which relies on a particular subalgebra of the four-dimensional relati…
Superconformal generalizations of auxiliary vector modified polynomial f(R) theories
Sibel Boran, Emre Onur Kahya, Nese Ozdemir +2
We present the supersymmetric completion of the auxiliary vector modified polynomial theories in their dual scalar-tensor theory formulation that interpolate between the aux…
Three-Dimensional Extended Lifshitz, Schrödinger and Newton-Hooke Supergravity
Nese Ozdemir, Mehmet Ozkan, Utku Zorba
We provide a systematic analysis of three-dimensional N = 2 extended Bargmann superalgebra and its Newton-Hooke, Lifshitz and Schrödinger extensions. These algebras admit invariant…
Unitary Extension of Exotic Massive 3D Gravity from Bi-gravity
Mehmet Ozkan, Yi Pang, Utku Zorba
We obtain a new 3D gravity model from two copies of parity-odd Einstein-Cartan theories. Using Hamiltonian analysis, we demonstrate that the only local degrees of freedom are two m…
Three-Dimensional Extended Newtonian (Super)Gravity
Nese Ozdemir, Mehmet Ozkan, Orhan Tunca +1
We present a three dimensional non-relativistic model of gravity that is invariant under the central extension of the symmetry group that leaves the recently constructed Newtonian…
Scale Invariance in Newton-Cartan and Hořava-Lifshitz Gravity
Deniz Olgu Devecioglu, Nese Ozdemir, Mehmet Ozkan +1
We present a detailed analysis of the construction of and scale invariant Hořava-Lifshitz gravity. The construction procedure is based on the realization of Hořava-L…
