Journal of High Energy Physics, 2022 The phase diagram on the θ-T plane in four dimensional SU(3) Yang-Mills theory is explored. We revisit the θ dependence of the deconfinement transition temperature, T c (θ), on the lattice through the constraint effective potential for Polyakov loop. The

Frontiers in Energy Research, 2022 Porcelain insulators play a vital role for the safety and stability operations of electric systems. In a strong electric field, these insulators easily break down and become zero resistance insulators, which impacts the safety and stability operations of

Pion screening mass at finite chemical potential
Journal of High Energy Physics, 2023 We present a method to compute the responses of meson screening masses to the chemical potential by Taylor expanding the correlator using lattice QCD simulation. We start by comparing the free theory lattice results with the analytical expression.

Zero sound and higher-form symmetries in compressible holographic phases
Journal of High Energy Physics, 2023 Certain holographic states of matter with a global U(1) symmetry support a sound mode at zero temperature, caused neither by spontaneous symmetry breaking of the global U(1) nor by the emergence of a Fermi surface in the infrared.

Possible superconductivity from incoherent carriers in overdoped cuprates
SciPost Physics, 2021 The non-superconducting state of overdoped cuprates is conjectured to be a strange metal comprising two distinct charge sectors, one governed by coherent quasiparticle excitations, the other seemingly incoherent and characterized by non-quasiparticle ...

Color superconductivity on the lattice — analytic predictions from QCD in a small box
Journal of High Energy Physics, 2023 We investigate color superconductivity on the lattice using the gap equation for the Cooper pair condensate. The weak coupling analysis is justified by choosing the physical size of the lattice to be smaller than the QCD scale, while keeping the aspect ...

Equation of state in two-, three-, and four-color QCD at nonzero temperature and density
Physical Review D, 2015 We calculate the equation of state at non-zero temperature and density from first principles in two-, three- and four-color QCD with two fermion flavors in the fundamental and two-index, antisymmetric representation. By matching low-energy results (from a `hadron resonance gas') to high-energy results from (resummed) perturbative QCD, we obtain results

Dense QCD2 with matrix product states
Journal of High Energy PhysicsWe study one-flavor SU(2) and SU(3) lattice QCD in (1 + 1) dimensions at zero temperature and finite density using matrix product states and the density matrix renormalization group.

Superconducting Quantum Critical Phenomena [PDF]
Reports in Advances of Physical Sciences, 2018 When the superconducting transition temperature Tc sufficiently approaches zero, quantum fluctuations are expected to be overwhelmingly amplified around zero temperature so that the mean-field approximation may break down.
