Phases of SU(2) gauge theory with multiple adjoint Higgs fields in 2+1 dimensions
Harley D. Scammell, Kartik Patekar, Mathias S. Scheurer +1
A recent work (arXiv:1811.04930) proposed a SU(2) gauge theory for optimal doping criticality in the cuprate superconductors. The theory contains Higgs fields transforming un…
Deconfined critical point in a doped random quantum Heisenberg magnet
Darshan G. Joshi, Chenyuan Li, Grigory Tarnopolsky +2
We describe the phase diagram of electrons on a fully connected lattice with random hopping, subject to a random Heisenberg spin exchange interactions between any pair of sites and…
Thermoelectric power of Sachdev-Ye-Kitaev islands: Probing Bekenstein-Hawking entropy in quantum matter experiments
Alexander Kruchkov, Aavishkar Patel, Philip Kim +1
The Sachdev-Ye-Kitaev (SYK) model describes electrons with random and all-to-all interactions, and realizes a many-body state without quasiparticle excitations, and a non-vanishing…
Complex density wave orders and quantum phase transitions in a model of square-lattice Rydberg atom arrays
Rhine Samajdar, Wen Wei Ho, Hannes Pichler +2
We describe the zero-temperature phase diagram of a model of a two-dimensional square-lattice array of neutral atoms, excited into Rydberg states and interacting via strong van der…
Theory of a Planckian metal
Aavishkar A. Patel, Subir Sachdev
We present a lattice model of fermions with flavors and random interactions which describes a Planckian metal at low temperatures, , in the solvable limit of l…
Fermi-surface reconstruction without symmetry breaking
Snir Gazit, Fakher F. Assaad, Subir Sachdev
We present a sign-problem free quantum Monte Carlo study of a model that exhibits quantum phase transitions without symmetry breaking and associated changes in the size of the Ferm…
