The many-body physics at quantum phase transitions shows a subtle interplay between quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …
The deconfined quantum critical point (DQCP) is an example of phase transitions beyond the Landau symmetry-breaking paradigm that attracts wide interest. However, its nature has …
The deconfined quantum critical point (QCP), separating the Néel and valence bond solid phases in a 2D antiferromagnet, was proposed as an example of (2+ 1) D criticality …
The “symmetric mass generation”(SMG) quantum phase transition discovered in recent years has attracted great interest from both condensed matter and high energy theory …

These lecture notes introduce quantum spin systems and several computational methods for studying their ground‐state and finite‐temperature properties. Symmetry‐breaking and …
Presenting the physics of the most challenging problems in condensed matter using the conceptual framework of quantum field theory, this book is of great interest to physicists in …
We discuss physical properties of “integer” topological phases of bosons in D= 3+ 1 dimensions, protected by internal symmetries like time reversal and/or charge conservation …
The theory of deconfined quantum critical (DQC) points describes phase transitions at absolute temperature T= 0 outside the standard paradigm, predicting continuous …
Numerical studies of the transition between Néel and valence bond solid phases in two- dimensional quantum antiferromagnets give strong evidence for the remarkable scenario of …
