DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NKUA-HEP/17/
 ">Aspects of Entanglement Hamiltonians</a>\nby Erik Tonni (SISSA) as part 
 of NKUA HEP Seminars\n\n\nAbstract\nThe reduced density matrix of a spatia
 l subsystem can be written as the exponential of the entanglement (modular
 ) Hamiltonian\, hence this operator contains a lot of information about th
 e entanglement of the corresponding spatial bipartition. For some particul
 ar models\, states and bipartitions\, this operator is local\, but in gene
 ral it is expected to be non-local. \nWe discuss some entanglement Hamilto
 nians in two-dimensional conformal field theory and\, in the case of free 
 fermions\, also how to obtain them from lattice calculations. The modular 
 conjugation is closely related to the modular Hamiltonian. We discuss the 
 geometric action of this operator in two-dimensional conformal field theor
 y and its holographic gravitational counterpart in terms of geodesic bit t
 hreads.\n
