Cold atom simulation of interacting relativistic quantum field theories. [PDF]
Physical Review Letters, 2010 We demonstrate that Dirac fermions self-interacting or coupled to dynamic scalar fields can emerge in the low energy sector of designed bosonic and fermionic cold atom systems. We illustrate this with two examples defined in two spacetime dimensions. The

Physical Review Research, 2022 Entanglement is the fundamental difference between classical and quantum systems and has become one of the guiding principles in the exploration of high- and low-energy physics.

NON-INTEGRABLE QUANTUM FIELD THEORIES AS PERTURBATIONS OF CERTAIN INTEGRABLE MODELS [PDF]
, 1996 We approach the study of non-integrable models of two-dimensional quantum field theory as perturbations of the integrable ones. By exploiting the knowledge of the exact S -matrix and form factors of the integrable field theories we obtain the first-order

Applying the variational principle to (1+1)-dimensional quantum field theories. [PDF]
Physical Review Letters, 2010 We extend the recently introduced continuous matrix product state variational class to the setting of (1+1)-dimensional relativistic quantum field theories. This allows one to overcome the difficulties highlighted by Feynman concerning the application of

Renormalization of quantum field theories on noncommutative Bbb Rd, 1. Scalars [PDF]
, 1999 A non-commutative Feynman graph is a ribbon graph and can be drawn on a genus g 2-surface with a boundary. We formulate a general convergence theorem for the non-commutative Feynman graphs in topological terms and prove it for some classes of diagrams in

Dual PT-symmetric quantum field theories [PDF]
, 2005 Some quantum field theories described by non-Hermitian Hamiltonians are investigated. It is shown that for the case of a free fermion field theory with a γ 5 mass term the Hamiltonian is PT -symmetric. Depending on the mass parameter this symmetry may be

Pilot-wave theory and quantum fields
, 2010 Pilot-wave theories provide possible solutions to the measurement problem. In such theories, quantum systems are not only described by the state vector, but also by some additional variables.

Purely transmitting integrable defects [PDF]
, 2006 Some aspects of integrable field theories possessing purely transmitting defects are described. The main example is the sine-Gordon model and several striking features of a classical field theory containing one or more defects are pointed out.
