Shaper-based dispersion scan for the characterization of polarization-shaped laser fields
Darius Köhnke, Jan-Erik Havekost, Nick Robin Rother +4
We present a pulse-shaper-based dispersion-scan (d-scan) framework for the combined generation and characterization of polarization-tailored femtosecond laser fields. By integratin…
Contact big fiber theorems
Yuhan Sun, Igor Uljarevic, Umut Varolgunes
We prove contact big fiber theorems, analogous to the symplectic big fiber theorem by Entov and Polterovich, using symplectic cohomology with support. Unlike in the symplectic case…
Descent with algebraic structures for symplectic cohomology
Umut Varolgunes
We formulate and prove a chain level descent property of symplectic cohomology for involutive covers by compact subsets that take into account the natural algebraic structures that…
Closed string mirrors of symplectic cluster manifolds
Yoel Groman, Umut Varolgunes
For the base of a Maslov Lagrangian torus fibration with singularities consider the sheaf assigning to each the relative symplectic cohomology in degree of…
Framed structures in Floer theory
Mohammed Abouzaid, Yoel Groman, Umut Varolgunes
We resolve the long-standing problem of constructing the action of the operad of framed (stable) genus- curves on Hamiltonian Floer theory; this operad is equivalent to the fram…
