A flat-band perspective on the boson peak in amorphous solids
Shivam Mahajan, Long-Zhou Huang, Cunyuan Jiang +4
The boson peak is a characteristic anomaly of amorphous solids broadly defined as a low-energy excess in the density of states and heat capacity compared to the textbook prediction…

Revealing the Geometrical and Vibrational Properties of the Defects Driving the Boson Peak
Shivam Mahajan, Darryl Seow Yang Han, Cunyuan Jiang +2
In amorphous solids, the vibrational density of states shows an excess of modes over the Debye model, known as the boson peak, whose origin remains unclear. Studies suggest a link…
