This is a pedagogical review of the lattice study of finite density QCD. It is intended to
provide the minimum necessary content, so that it may be used as an introduction for …

Optical traps and lattices provide a new opportunity to study strongly correlated high spin
systems with cold atoms. In this article, we review the recent progress on the hidden …

A recent proposal is that dark matter could be a thermal relic of 3→ 2 scatterings in a
strongly coupled hidden sector. We present explicit classes of strongly coupled gauge …

We propose a new method to investigate the thermal properties of QCD with a small quark
chemical potential μ. Derivatives of quark and gluonic observables with respect to μ are …

Due to the sign problem, it is exponentially difficult to study QCD on the lattice at finite
chemical potential. We propose a method—an overlap improving multi-parameter …

Important progress in understanding the behavior of hadronic matter at high density has
been achieved recently, by adapting the techniques of condensed matter theory. At …

We discover a quantum Monte Carlo (QMC) method to solve the fermion sign problem in
interacting fermion models by employing a Majorana representation of complex fermions …

Spectral densities encode nonperturbative information that enters the calculation of a
plethora of physical observables in strongly coupled field theories. Phenomenological …

Quantum Monte Carlo (QMC) simulations involving fermions have a notorious sign problem.
Some well-known exceptions to the auxiliary field QMC algorithm rely on the factorizibility of …

We consider the S p (4) gauge theory coupled to N f= 2 fundamental and nf= 3 antisymmetric
flavors of Dirac fermions in four dimensions. This theory serves as the microscopic origin for …
