Supersymmetric quantum mechanics on the lattice: III. Simulations and algorithms

Nuclear Physics B, 2015
In the fermion loop formulation the contributions to the partition function naturally separate into topological equivalence classes with a definite sign.

Fermion parity resolution of entanglement

Journal of High Energy Physics
Entanglement is analyzed in the Majorana fermion conformal field theory (CFT) in the vacuum, in the fermion state, and in states built from conformal interfaces.

Holography for Sp(2N c ) gauge dynamics: from composite Higgs to technicolour

Journal of High Energy Physics
We study Sp(2N c ) gauge dynamics with two Dirac fermion flavours in the fundamental representation. These strongly coupled systems underlie some composite Higgs models with a global symmetry breaking pattern SU(4)→Sp(4), leading to a light quartet of ...

Untwisted moduli and internal fermions in free fermionic strings

Nuclear Physics B, 1995
We investigate the dependence of the number and type of untwisted moduli on the boundary condition vectors of relistic free fermionic strings. The number of moduli is given by six minus the number of complex internal world--sheet fermions and the type of moduli is determined by the details of the world--sheet left--right asymmetry of the boundary ...

A pseudo-fermion propagator approach to the fermion sign problem

The Journal of Chemical Physics
In this work, within the framework of path integral Monte Carlo, we construct a pseudo-fermion propagator by replacing the original fermionic determinant with its absolute value. This modified propagator defines an auxiliary system free from the fermion sign problem, enabling efficient simulations of fermionic systems.

Localization of matter fields on flat fermion brane

European Physical Journal C: Particles and Fields
In this paper, we investigate the localization of matter fields on a flat fermion thick brane. To localize scalar and fermion fields within a five-dimensional spacetime, we introduce the Yukawa coupling mechanism.
