In search of diabolical critical points
Naren Manjunath, Dominic V. Else
A phase transition is an example of a ``topological defect'' in the space of parameters of a quantum or classical many-body systems. In this paper, we consider phase diagram topolo…
Anomalies of global symmetries on the lattice
Yi-Ting Tu, David M. Long, Dominic V. Else
't Hooft anomalies of global symmetries play a fundamental role in quantum many-body systems and quantum field theory (QFT). In this paper, we make a systematic analysis of lattice…
't Hooft anomalies in metals
Dominic V. Else
I review some recent results on understanding the physics of metals in an exact non-perturbative way through the powerful field-theoretic concepts of emergent symmetries and 't Hoo…
Anomalous continuous symmetries and quantum topology of Goldstone modes
Naren Manjunath, Dominic V. Else
We consider systems in which a continuous symmetry , which may be anomalous, is spontaneously broken to an anomaly-free subgroup such that the effective action for the Golds…
Topological Phases of Many-Body Localized Systems: Beyond Eigenstate Order
David M. Long, Dominic V. Else
Many-body localization (MBL) lends remarkable robustness to nonequilibrium phases of matter. Such phases can show topological and symmetry breaking order in their ground and excite…
Holographic models of non-Fermi liquid metals revisited: an effective field theory approach
Dominic V. Else
Accessing the physics of strongly coupled metals in a controlled way is a challenging problem in theoretical condensed matter physics. In this paper, we revisit the possibility of…
Collisionless dynamics of general non-Fermi liquids from hydrodynamics of emergent conserved quantities
Dominic V. Else
Given the considerable theoretical challenges in understanding strongly coupled metals and non-Fermi liquids, it is valuable to have a framework to understand properties of metals…
Loop current fluctuations and quantum critical transport
Zhengyan Darius Shi, Dominic V. Else, Hart Goldman +1
We study electrical transport at quantum critical points (QCPs) associated with loop current ordering in a metal, focusing specifically on models of the "Hertz-Millis" type. At the…
Gifts from anomalies: Exact results for Landau phase transitions in metals
Zhengyan Darius Shi, Hart Goldman, Dominic V. Else +1
Non-Fermi liquid phenomena arise naturally near critical points of Landau ordering transitions in metallic systems, where strong fluctuations of a bosonic order parameter destroy c…
Critical drag as a mechanism for resistivity
Dominic V. Else, T. Senthil
A quantum many-body system with a conserved electric charge can have a DC resistivity that is either exactly zero (implying it supports dissipationless current) or nonzero. Exactly…
Quantum many-body topology of quasicrystals
Dominic V. Else, Sheng-Jie Huang, Abhinav Prem +1
In this paper, we characterize quasicrystalline interacting topological phases of matter i.e., phases protected by some quasicrystalline structure. We show that the elasticity theo…
Topological Goldstone phases of matter
Dominic V. Else
We consider the possibility for phases of matter in which a continuous symmetry is spontaneously broken in a \emph{topologically non-trivial} way, which, roughly, means that the ac…
Strange metals as ersatz Fermi liquids
Dominic V. Else, T. Senthil
A long standing mystery of fundamental importance in correlated electron physics is to understand strange non-Fermi liquid metals that are seen in diverse quantum materials. A stri…
Non-Fermi liquids as ersatz Fermi liquids: general constraints on compressible metals
Dominic V. Else, Ryan Thorngren, T. Senthil
A system with charge conservation and lattice translation symmetry has a well-defined filling , which is a real number representing the average charge per unit cell. We show tha…
Long-lived interacting phases of matter protected by multiple time-translation symmetries in quasiperiodically-driven systems
Dominic V. Else, Wen Wei Ho, Philipp T. Dumitrescu
We show how a large family of interacting nonequilibrium phases of matter can arise from the presence of multiple time-translation symmetries, which occur by quasiperiodically driv…
Topological theory of Lieb-Schultz-Mattis theorems in quantum spin systems
Dominic V. Else, Ryan Thorngren
The Lieb-Schultz-Mattis (LSM) theorem states that a spin system with translation and spin rotation symmetry and half-integer spin per unit cell does not admit a gapped symmetric gr…
Discrete Time Crystals
Dominic V. Else, Christopher Monroe, Chetan Nayak +1
Experimental advances have allowed for the exploration of nearly isolated quantum many-body systems whose coupling to an external bath is very weak. A particularly interesting clas…
Crystalline topological phases as defect networks
Dominic V. Else, Ryan Thorngren
A crystalline topological phase is a topological phase with spatial symmetries. In this work, we give a very general physical picture of such phases: a topological phase with spati…
Fragile topological phases in interacting systems
Dominic V. Else, Hoi Chun Po, Haruki Watanabe
Topological phases of matter are defined by their nontrivial patterns of ground-state quantum entanglement, which is irremovable so long as the excitation gap and the protecting sy…
Cheshire charge in (3+1)-D topological phases
Dominic V. Else, Chetan Nayak
We show that (3+1)-dimensional topological phases of matter generically support loop excitations with topological degeneracy. The loops carry "Cheshire charge": topological charge…
Gauging spatial symmetries and the classification of topological crystalline phases
Ryan Thorngren, Dominic V. Else
We put the theory of interacting topological crystalline phases on a systematic footing. These are topological phases protected by space-group symmetries. Our central tool is an el…
Classification of topological phases in periodically driven interacting systems
Dominic V. Else, Chetan Nayak
We consider topological phases in periodically driven (Floquet) systems exhibiting many-body localization, protected by a symmetry . We argue for a general correspondence betwee…

Dominic V. Else, Stephen D. Bartlett, Andrew C. Doherty
We generalize the hidden symmetry-breaking picture of symmetry-protected topological (SPT) order developed by Kennedy and Tasaki in the context of the Haldane phase. Our generaliza…
